- 18-Jun
- The bisulfite conversion was missing a negative control (bisulfite converted but unmethylated c0051) we'll need this to interperet results
- Miniprep c0078, c0079 + make glycerol stocks check same plasmid with our kit
- Order 13420 (second zfp)
- Design a way to make variable promoters more easily varied (for a biobrick so teams can use the reporter plasmid for their own nefarious reasons)
