Transformations in Shewie

About 250 ng of DNA added each time.

Poor transformation efficiency in the positive control suggests that there may be a problem with our cells. All samples, except for P102, were retransformed the following week with fresh cell cultures.

Second Set (with new cells) 8/27

Getting Thermoinducible and Lac Inducible GFP into pSC101

Digests of Inducible Systems and pSC101 8/27

P102 needs to be retransformed so it was not included in this set.

Gel of Digest 8/27

mtrB TOPO bands were cut (2.2 kB) but P124-5 did not cut properly, suggesting that there was an extra cut site that was cutting the insert into two pieces.

Single-cut Digest of P124-5 8/27

Getting mtrB onto thermo and lac inducible systems

Ligating mtrB TOPO with RBS

Grew up more mtrB TOPO for next week.

PCR of mtrB with RBS + mtrB primers

Scheduled for next week.
