Results of Competent Cells Testing

 * The DH5α A and B stocks and DB3.1 cells all had red colonies that were too numerous to count
 * All cells are competent, the few cell count on previous testing was likely due to the pUC19 plasmid
 * Glycerol stocks of A and B stocks DH5α cells were made by:
 * Adding 0.618mL 100% glycerol to 3.8mL competent cells to make a 14% glycerol solution
 * Store in -80°C freezer

Transformation of pBADwt+RFP and pBADweak+RFP into BW27783

 * As pBADwt+RFP and pBADweak+RFP are currently just in DH5α glycerol stocks, need to transfer them to BW27783 cells which will have homogenous induction in the population upon stimulation with arabinose
 * The plasmids were transformed using the iGEM:British Columbia Transfromation protocol with 3μL of miniprepped pBADwt+RFP and pBADweak+RFP
 * A control transformation performed under the same conditions except for 1μL of 5ng/μL J23100 miniprepped plasmid was used
 * J23100 cells were plated on Amp
 * pBADwt+RFP were plated on Chlor
 * pBADweak+RFP was plated on Amp-Tet
