Genetic modification
We're interested in doing genetic modification on micro-organisms at the London Hackspace. Ideas for stuff to do:
- The standard GFP experiment
- Get some ideas from iGem teams
Needed for GFP experiment (that we don't already have):
Fridge? Incubator. Build or buy. Cleaning: Bleach, gloves, paper towels, hand cleaning gel. Bunsen burner + fuel. Glassware, pipettes, tools. Ethanol. Lots.
To apply for a license we will probably first need: Written protocols for stuff, especially cleaning up.
Disposal. Chemical. Sterilisation. Do we need incineration? Find a waste disposal company that will take biohazard material?
Restriction enzymes. At least two. Pricey? GFP plasmid. Antibiotics. Ampicillin. Initial e. coli culture. Growth medium/ broth. LB. Plates. Standard 10cm plates. Agarose. Ice. 40C bath.
Proper storage.
Centrifuge - bigger : hold
Miniprep kit
Maxiprep kit
Growing competent E. coli
Here is the protocol we used with UCL to grow competent cells during the making of the public biobrick. So we need to get E. coli (cannot find how to buy this yet), LB - £66, 0.1M CaCl2 - £32.50, M9 salts - £57.60, MgSO4 - £20, bacteriological agar solution - £42.90, thiamine - ~£20, D glucose - ~£20, and plates. All links are only the first ones I found, maybe cheaper options available.
Self-cloning
Here's a protocol to do a 'self-cloning' transformation, which we would not need a licence for, and so could do now to practise.
Kit:
- Kit has enough materials "for 16 students, working in pairs" - so 8.
Timescale:
- Day 1 - prepare bacterial culture plates, incubate at room temperature in the dark
- Before session - make agar plates and refrigerate
- Day 5 - Class
- Incubate plates overnight
- Day 6 - Examine results
Requirements:
- We'll need a fridge to store E. coli culture on arrival, LB plates once made, and culture plates if there's a delay between incubation and visualisation.
- Need an incubator (that is dark inside)
Storage when materials arrive:
- Some reagents must be stored at -20. E. coli should be refrigerated.
- Once E. coli pack is opened needs to be used in a few days.
- Shipped first class post mon - thurs
Legal
There are a number of things we have to do in order to set up a GM lab.
The relevant regulations are The Genetically Modified Organisms (Contained Use) Regulations 2000 (PDF)
Here is a summary of those regulations: GMO Regulations 2000 summary
New lab
Financial feasibility
Income:
- Current membership fee is £8 a month.
- At the moment I would say maximum paying members we could get is 10.
- So we'd make £80 a month from membership fees. We could increase membership fees for people who are very active.
Costs:
- Rent, lets say £500 a month
- Other space costs. Utility bills, business rates/council tax.
- Reagents. We should work out cost per reaction, assuming an extraction, PCR and electrophoresis. I estimate this will be between £1 and £5 per reaction.
So we have a big funding shortfall.
Options for new space
- Talk to Russ/Jonty/another trustee about accomodating us in the new hackspace. Ie. a bigger room that we could apply for a licence for. (We have no idea when the move will happen)
- Investigate funding from other sources as cannot fund an independent space ourselves.
Funding sources:
- Wellcome trust public engagement fund
- Arts catalyst
- Synthetic aesthetic
- UCL. Imperial.
- Workshops
- Kickstarter
- Businesses to get free kit from
- BBC for new publicity.
- NESTA
- NCBE
Requirements for lab
- Tiling / washable surfaces
- Sink
- Lockable
- Enough room for 10-15 people to work
