How to Manage a Biotech Lab Ellyn Daugherty SM Biotech Career Pathway www.SMBiotech.com www.BiotechEd.com www.emcschool.com/biotechnology www.sargentwelch.com/biotech Ellyn@BiotechEd.com 650-400-9424 Setting up and Managing a Biotech Lab Things to Consider: • • • • • • • • • • • Lay-out/Workflow/Storage Lab Stations Common Work Areas Chemicals/Chemical Storage Refrigerator/Freezer Storage Student Sample Storage Waste Disposal Other Safety Issues Inventory/Ordering Managing Time Other Issues Facility Lay-out/Workflow/Storage • Consider student movement, bottlenecks, & time constraints • Set up at individual lab stations vs. common work areas, or vice versa • Replicate work areas - avoid long waits and “long distance” • Strategically placed tables, carts, deionized water, sinks • Gas/Bunsen burner placement (needed only in hoods) • Storage areas - immediate, shortterm, and long-term Lab Stations • Students work at lab station in pairs (lab partners) • 2 pairs at a lab station (lab table) • A minimum on the lab table > 1 hot plate stirrer/lab station > 1 spectrophotometer/lab station > a trash bucket/lab station > 1 (serological) pipet rack/table > 1 micropipet stand/table > a box of gloves/table • Strategic use of drawers and cabinets > Small instrument drawer (pipet pumps, micropipet tips, pen, tape, scissors, goggles, etc.) > Student storage drawer > Small equipment & reagent cabinet (gel boxes, power supplies, large volumes of buffer, etc.) Common Work Areas • In strategic locations – common work stations > electronic & analytical weighing stations > pH meter/pH adjustment station > centrifuge station, UV spec station > refrigerators and freezers (mini-?) > gel staining and visualization station > incubation ovens, water baths, heat blocks, microwaves > deionized water (dH20) > autoclaves and drying ovens > supply tables/supply carts • Hoods > Laminar flow hoods vs. bio-safety cabinets (for sterile work, protect user and samples) > Chemical fume hoods (for dispensing organics, caustics, flammables, noxious) Chemicals & Chemical Storage • Chemicals must be stored probably to protect user and reagents • Most districts have specific policies for chemical storage (find out about yours) • Chemical storeroom/chemical cabinet for “general safe” chemicals = green labels • Flammables cabinet for alcohols, etc = red labels • Oxidizers/ cabinet for bases, acids, peroxides = yellow and labels • Toxics cabinet (locked) for EtBr = blue labels • Chemical fume hood (built in vs portable) • Gloves (latex vs. nitrile vs. others) and goggles See www.scholarchemistry.com for much more information on chemical safety Refrigerator/Freezer Storage • Most samples are labeled with storage temp • Virtually all protein, DNA, and cell samples must be stored at 4°C (refrig) or at -20°C (lab freezer) > Store lyophilized (powdered) protein or DNA samples at -20°C, unless otherwise labeled > Store protein samples alphabetically > Record the date on reagents upon arrival, then record when the sample is first opened > Certain cell lines must be stored at -70°C or below or lose competence or viability • Do not use defrosting (cycling) refrigerator/freezers • Repeated freezing/thawing compromises most samples (aliquot samples on receipt into more usable volumes) • If possible, have designated refrigerators and Student Sample Storage • Room Temp Storage > chemicals, many buffers • Refrigerator/Cooler (4°C) Storage > most protein or DNA student samples • Freezer (-20°C) Storage > some protein or DNA student samples > glycerol stock/cell samples for IR (?) (some required -80°) • The more you can separate student samples the more time is saved > Consider separate lab refrigerators and freezers (4.0 cu ft models) or different shelves in large volume coolers or freezers Waste Disposal • Most districts have specific policies for waste disposal (find out about yours) • Most hazardous waste must be collected and disposed of by professionals • Need biohazard bags for biological hazards = plates (no sharp items), fill only ½ full • Autoclave bio-contaminated items 15-20 mins @15-20 psi before trash • Bio-contaminated loops and tubes can be soaked in 10% bleach for 30 min before regular trash • Many chemicals may not go down drain (see district rules), ie. CuSO4, silver nitrate, EtBr?, etc • Label waste with type/concentration/date Other Safety Issues • Gloves and goggles at every lab station and workstation, for all chem work • No gloves for work with Bunsen burner or microwave (burn hazard). Explore silicon gloves. • Use hot hand protectors or lab mitts for hot bottles/beakers • Disinfectants at each hood (1x Lysol® or Amphyl®), where bacteria is used • Use of 10% bleach or 70% EtOH, where plant tissues are used • Use of lid-locks for 1.7 mL tubes and hot heat blocks • Safety shower, eyewash • Broken glass cartons, fire extinguisher at several places Inventory/Ordering • Keep a record (Excel® spreadsheet with vendor, manufacturer, description, package size, part number, etc.) of all materials used and received. • Use inventory sheets to help keep areas clean and organized • Assign student groups the responsibility to maintain/inventory a particular area > Chem Stockroom A-G > “Darwin” Refrigerator > Weigh Stations > “Watson”, “Crick” Freezers • Have inventory sheets at each lab station and require inventory sign-off at the beginning and end of class (Biotech Live Ch 3) • Have a place that students can record when a “last bottle” is ½ full (use to amend orders) • Make time for inventory and lab station/workplace maintenance Managing Time • Decide what is really important for YOU to do > what things should you really grade and how should you grade them > what task others can do for you (students, administrators, committee members) > how many jobs do you actually have (teaching, coaching, dept chair, etc.) • Start learning some of the faster, better, cheaper ways of doing some of the lab techniques. > faster agarose gels (LB buffer system) > faster protein PAGE gels (UV-gel system) > DNA visualization dye in the loading dye > faster restriction digestion enzymes > using high-efficiency competent cells for transformation • Start thinking like a CEO (of your biotech company) Other Issues • Computers – keep them away from chemicals and water • Not enough space – portable items? • Alphabetized small items drawers or containers • Cable-lock down balances, computers • Designated hand-washing sinks? • Lots of paper towels used • Crushed ice needed/preferred • Post emergency numbers • Biotech teacher “in charge” of facility • Keep getting professional development • Network with other biotech educators and ask them questions (especially about new methods, techniques, equipment) Other Issues – Getting the Support You Need • Financial – Books, Lab Manuals, CDs, etc. – Equipment/Supplies (Grants, Donations, Giveaways, Bio-Link Depot, BABEC, Partnerships, etc.) – Computers – Release Time • Curriculum/Professional Development – Books, Lab Manuals, CDs, etc. – Workshops and Conferences • Moral – Reasonable expectations from Admin – From Counseling, Clerical, and Admin – Designated Classroom – Reasonable amount of Preps – Reasonable amount of Students – Reasonable Budget Get even more help!
