For added convenience, TSS-treated competent cells can be prepared in advance and stored at –70°C for later use with little or no loss in transformation efficiency. For example, TSS-treated competent E. coli JM109 cells showed no significant loss of... We have modified the preparation of competent cells from the heat-shock procedure and combined it with transformation by electroporation to yield a condensed protocol that works consistently with auxotrophic markers or antibiotic selection.
