FAQ
E. coli cells prepared with ZymoBroth growth medium exhibit faster transformation kinetics and higher transformation efficiencies. This may be as high as several folds to a log increase in comparison to SOB. Compared to SOB, LB could reduce the transformation efficiency by 2-5 folds. ZymoBroth increases transformation efficiency, typically on the order of 5 to 100-folds for most labs strains.
The ZymoBroth is fine to use. The precipitation is due to salts coming out of solution. Warm the ZymoBroth at 37°C to re-dissolve.
