Usage and Sectoring of Cell Culture Laboratory

A noteworthy element that recognizes tissue culture research laboratories from most different sorts of laboratories is the necessity to keep up the replication of a biologic culture under sterile conditions(monoseptic), especially guaranteeing the nonexistence of microscopic organisms and growths. The facilities that are required along these lines must fulfill this unordinary require in the idea of hardware and research laboratory outline(N. & J, n.d.) The perfect method to design a tissue culture research center is to begin nothing but a clear bit of paper. Reasonably, be that as it may, this is once in a while conceivable as budgetary imperatives as a rule force the need to change over existing facilities as opposed to work from new. This does not really imply that adjusted new facilities will be mediocre, in activity as well as wellbeing terms, to a reason outlined lab, provided specific rules are taken after(Morris, 1998)

Assigned working zones are an essential to giving a smooth running cell culture research center. By separating every action, contaminations and related dangers to both the administrator and materials are decreased to a base. Some key activities that must have a dedicated work area of its own are,

• preparation of sterile hardware and media
• gathering and culture of recently settled or approaching cells;
• culture of cells which have gotten in-house testing for microbial contamination
• storage cells requiring exceptional conditions to forestall contamination (ex. cells utilized as a part of the generation of diagnostic and therapeutic operators)
• cryopreservation and cell storage

Laboratories ought to be designed to be in sensitivity for the common stream of movement in a typical working day, while in the meantime limiting the likelihood of contamination of cells and of laborers by unessential organisms(fungi, virus, mycoplasmas and bacteria). It is imperative that waste and contaminated material ought not be permitted to accumulate, as mischances are possibly more perilous with bigger volumes of waste which will be clumsier for research facility staff to deal with. Proper task is all the more effortlessly accomplished by giving separate working regions assigned for particular functions. Before finishing the structure of these work regions it is basic to affirm that the proposed configuration is consistent with nearby or national rules and regulations. This will avoid all the time, energy and resources wastage (“PERSPECTIVE ON : A CELL CULTURE LAB STAYIN ’ ALIVE,” 2014)

When designing plans for a global support it might likewise be important to think about foreign and global administrative prerequisites for quality what's more, security. While all very much outlined cell culture research laboratories will have numerous fundamental highlights of outline and task in like manner, the particular highlights of each research laboratory will rely upon numerous elements. These incorporate not just the evident imperatives of existing offices and assets, yet in addition the transmit for the research laboratory's work, and administration strategy(Morris, 1998).

The laboratory might be required to do quite certain examination or examinations with obviously portrayed dangers. Then again the work may include general strategies(e.g.analytic work) consolidating a more extensive scope of less all around characterized dangers. Along these lines a general hazard appraisal of proposed work might be required. It is essential to recollect that, as an issue of administration arrangement, quality and wellbeing go as an inseparable unit and ought not be managed in confinement, especially at the lab outline and arranging stages(Archer et al., 1993)

Lab design

1. Culture room – Glassware washing machine & dryer
2. Refrigerator – Water bath
3. Freezer – Plastic ware/glassware and
4. Storage – Centrifuge
5. Biosafety cabinets – Transfer area

This is a design for a medium sized cell culture laboratory which can be utilized by 4-6 people. And consists of rooms, sections and equipments as follows.

Sectioning

Washing area

The washing zone ought to contain comparatively large sinks, some lead-lined to oppose acids and antacids, depleting sheets, and racks, and have access to demineralized water, distilled water, and double-distilled water. Space for drying broilers or racks, automated glassware washing machine, acid baths, pipette washers and driers, and storage cupboards ought to likewise be accessible in the washing area.(Area & Room, n.d.)

Media preparation area

The media preparation area ought to have plentiful storage space for the chemicals, culture vessels and terminations, and glassware required for media prepping and apportioning. Bench area is for microscopes, cell counters, hot plates/stirrers, pH meters, balances, water baths, and media dispensing hardware ought to be accessible(Connor, Driscoll, & Introduction, 2005)Other important equipments may incorporate air and vacuum sources, distilled and double-distilled water, Bunsen burners with a gas source, a microwave or a convection stove, and an autoclave or on the other hand residential pressure cooker for cleaning media, glassware, and instruments. This area also includes biosafety cabinets and sometimes incubators(Area & Room, n.d.)

Transfer area

Under clean and dry conditions and in small sized tissue culture laboratories tissue culture systems can be efficiently performed on an open bench area. In any case, it is fitting that a laminar stream hood or steriled room be used for making exchanges. All surfaces in the transfer area ought to be planned and developed in such a way, to the point that residue and microorganisms don't amass and the surfaces can be altogether cleaned and sanitized. Laminar floor hoods are kept in this area(N. & J, n.d.)

Culture room

A wide range of tissue cultures ought to be incubated under conditions of all around controlled temperature, dampness, air flow, and light quality and length. These ecological components may impact the development and separation process specifically amid culture or by implication by influencing their reaction in resulting ages. Protoplast societies, low-thickness cell suspension societies, and anther societies are especially delicate to ecological social condition(Morris, 1998)

Ordinarily, the way of life space for development of plant tissue societies ought to have a temperature in the vicinity of 15° and 30° C, with a temperature vacillation of under 0.5°C; notwithstanding, a more extensive run in temperature might be required for particular examinations. It is additionally prescribed that the room have an alert framework to demonstrate when the temperature has achieved preset high or low temperature limits, and also consistent temperature recorder to screen temperature vacillations. The temperature ought to be steady all through the whole culture room. The way of life room ought to have enough fluorescent lighting to achieve the 10,000 lux; the lighting ought to be movable as far as amount and photoperiod length. Both light and temperature ought to be programmable for a 24-hr period. The way of life room ought to have genuinely uniform constrained air ventilation, and a dampness scope of 20-98% controllable to 3 percent(Area & Room, n.d.)

Storage room

Storage area is used to store cell samples and other materials. More incubators, refrigerators, freezers, cryostorage units are placed inside. Part of the storage area consists of liquid nitrogen store. It is best located on an outer wall with ventilation to the outside and easy access for deliveries. If the freezer store is adjacent, freezers may be filled directly from an overhead supply line and flexible hose. Doors are left open for ventilation during filling, and a wall-mounted oxygen alarm with a low-mounted detector sounds if the oxygen level falls below a safe level(Connor et al., 2005)

Quarantine area

This area is used to prevent the contamination of exogenous microorganisms in the laboratory. Scientists get quarantined and minimize the encounter of other microorganisms and pathogens.

Instrumentation

Because of the idea of a cell culture lab, the hardware is composed and organized to enhance work process while disapproving of potential physical bottlenecks. The cell culture lab contains biosafety cabinets, incubators, microscopes, cell counters, centrifuges, water baths, refrigerators, freezers, cryostorage units and numerous pipettors and pipette aids.

Bench

Since the above design is for a small/medium sized laboratory which can be utilized by 4-6 people a large bench area is used for preparation of specimens instead of a separate room. In the bench area an ample area is dedicated to keep all the chemicals, glassware and all the consumables that will be necessary for the procedure along with the water bath. And in the rest of the space, four microscopes, two cell counters, an autoclave and all the necessary equipments like hot plates/stirrers, pH meters, balances are placed for ergonomic reasons.

Microbiological safety cabinets

A microbiological security cabinet is likely the most imperative bit of hardware for cell culture since, when worked accurately, it will give a spotless workplace to the item, while shielding the administrator from mist concentrates. In these cupboards administrator or potentially item insurance is given using HEPA(high proficiency particulate air)channels. The level of control gave shifts as per the class of cabinet utilized(Class & Class, n.d.)Cupboards might be ducted to environment or re-flowed during a time HEPA channel before going to atmosphere. Environmental observing with Tryptose Soya Broth agar settle plates inside the cupboard for at least four hours is a decent marker of how clean a cupboard is(Cabinet & Guidelines, 2009)There ought to be no development of microorganisms or organisms on such plates. By and large a class 2 cabinet is sufficient for animal cell culture. Nonetheless, each investigation must be evaluated for its peril hazard and it is conceivable that extra factors, for example, a known infection contamination or a questionable provenance may require a more elevated amount of control(Class & Class, n.d.) These cabinets are placed near to the media preparation area for easy access

Centrifuge

Centrifuges are utilized routinely in tissue culture as a component of the subculture routine for most cell lines and for the arrangement of cells for cryopreservation. By their extremely nature centrifuges create mist concentrates and therefore it is important to limit this hazard. This can be accomplished by acquiring models that have fixed cans(Vibration, n.d.)Centrifuge ought to have a cover so the state of the heap can be seen without opening the top. This will lessen the danger of the administrator being presented to perilous material if a centrifuge tube has broken amid centrifugation. Care ought to dependably be taken not to over fill the tubes and to adjust them. These straightforward advances will diminish the danger of pressurized canned products being created. The centrifuge ought to be arranged where it can be effortlessly gotten to for cleaning and support. They ought to be checked much of the time for indications of consumption. A little seat top rotator with controlled braking is sufficient for generally purposes. Higher gravitational powers may cause harm and advance agglutination of the cell pellet(Connor et al., 2005)

For ergonomic reasons, the unit ought to be situated close to the biosafety cabinet and at a fitting height. All centrifuges will vibrate to some extent, and measures ought to be taken to guarantee that such vibrations can't harm other lab equipments, cause superfluous commotion, or enable the centrifuge to conceivably fall(Ultracentrifuge, Ultracentrifuge, Ultracentrifuge, & Angle, 2012) So it’s best not to place the centrifuge on the bench area where the preparation takes place but it must be close to the preparation area.

Incubators

Cell cultures require an entirely controlled condition in which to develop. Expert incubators are utilized routinely to give the right development conditions, for example, temperature, level of stickiness and CO2 levels in a controlled and stable way. By and large, they can be set to keep running at temperatures in the scope of 28°C(for bug cell lines)to 37°C(for mammalian cell lines) and set to give CO2 at the required level(e.g. 5-10%)A few incubators additionally have the office to control the O2 levels(Innovation & Platform, n.d.)Copper-covered hatcheries are likewise now accessible. These are accounted for to lessen the danger of microbial contamination inside the incubator because of the microbial inhibitory movement of copper. The incorporation of a bactericidal specialist in the incubator water plate will likewise decrease the danger of bacterial and contagious development. Nonetheless, there is not a viable replacement for consistent cleaning(Area & Room, n.d.)General cell culture incubators require the surrounding temperature to be normally 5–10°C colder than the objective temperature. On the off chance that the encompassing temperature is excessively near the objective temperature, standard units can overheat, influencing temperature to control in the room fundamentally essential for dependable task(“Incubation and Embryology For Teachers and 4-H,” n.d.)So in this plan the incubator is placed near to the laminar floor hood to decrease temperature changes, which could make an impact cultured cells. And also the incubator is ideal to be kept on a standing height so the requirement for constant bending is not needed(Area & Room, n.d.)
