Checked plates - growth on all 4 plates

new DH5alpha plates look contaminated. Staph? Not sure.

old competent cells look OK. Should we just go back to our old cell line? It seems the issue was a plasmid dilution issue rather than a competent cells issue.

re-plating with the following plasmid dilutions:

currently have 23ng/ul, to get to 10ng/ul mix 4.35ul plasmid and 5.65 ul dH2O

1 ng = 1ul of previous mix in 9ul of dH2O

.01 ng = 1ul of previous mix in 9ul of dH2O

after mixing each plasmid concentration, follow the Transformation Protocol.
