RapidTrans are high-efficiency competent E. coli supplied in either 20 vials or a 96-tube tray. This convenient format gives you the freedom to perform from 1 to 96 transformations at a time, without thawing more tubes of cells than needed. Thus, RapidTrans eliminates the reduced efficiencies that occur as a result of repeated freezing and thawing and makes possible high-throughput transformation. The cells are provided complete with SOC media, supercoiled pUC19 DNA control; the 96-well plate formats include sterile reservoirs for use with multi-channel pipettors.
