Wetlab work
Checked transformants from yesterday

| Construct
| Colony forming units

| I14032 (plac) + B0030 (rbs)
| 3

| pnir + B003 (rbs)
| 0
|
| E0040 (GFP) + B0015 (tt)
| 1

| GFPf + B0015 (tt)
| 2 + 2 clusters of colonies

- Colony PCR'd transformants
- 30 cycles, anneal at 62C, extend for 1 min.
- Ran on EtBr stained 2.0% agarose gel at 95V for 1 hour
- None of the transformations were successful :o(
Determined DNA concentrations of purified RE'd PCR products from 8/4

Prepared PCR'd nir and J33207 (from yesterday) for transformation/ligation
- Grace
- Ran PCR products on EtBr stained 2.0% agarose gel at 60V for 100 min.
- nir band at 330bp confirmed
- J33207 = 4 bands (1.5kb, 2.5kb, 3.2kb, 10kb), none of which are correct
- [http://www.partsregistry.org partsregistry] says J33207 DNA is inconsistent
- Extracted nir and 1.5kb J33207 band from gel
- RE digested in 50 μl rxns with EcoRI and SpeI in NEBuffer 2
- Larger rxn volume may improve digest efficiency
- Incubated at 37C for 2.5 hours
- RE digested 10 μl J33207 plasmid prep with EcoRI and SpeI in NEBuffer 2
- To confirm plasmid prep; if good, will use for ligation rxn
- Incubated at 37C for 2 hours
- Ran RE digests on EtBr stained 2.0% agarose gel at 72V for 100 min.
Made LB+amp100 plates
