May 25/2010
(in the lab:JV, HB, AV)
Objective: Transform the following ligated parts:
- pLacI-sRBS (single cut from May 18,2010)
- pLacI-sRBS (double cut from May 18,2010)
- pLacI-sRBS-lumazine synthase-dt (from May 18, 2010)
Method:
Used Competent Cell Transformation to prepare plasmid DNA.
Results:
No colonies grew. No colonies on positive control plate. Something amiss here.
NOTE (June 1/2010; AS): Likely that the problem here was the method used to heat shock the cells. Cells were heat shocked in a heat plate, with incomplete contact of the heating surface, causing inefficient transfer of heat to cells for shock and movement of DNA into competent cells.
