To Do

 * make more 1161 + tet plates
 * make more 1161 medium
 * make LB Tet and LB Amp plates

Transformation results

 * pUC19 10 pg/ul control transformation, plating 0.1 fraction is about 300 colonies
 * efficiency is 300*10(fraction)*1e7(10 pg to 1 ug) or 3e10 cfu/ug
 * Transposon insertion was 6 colonies, plating 0.1 fraction
 * efficiency 60 colonies per 25 ng DNA, or 60*40 cfu/ug = 2.4e3 cfu/ug
 * This is 40x below transformation efficiency test of Epicentre
 * presumably this is due to the DNA used. Let's try a higher DNA concentration
 * After six more hours, 9 colonies showed up. This is 3.6e3 cfu/ug
 * 11x less than previous attempt, but 3x less than previous not outgrown 2 hours
 * 27x less than Epicentre transformation efficiency QC test

Web finds
