For custom biotinylation of proteins, Sigma offers kits for conjugation on two different scales. The biotin-avidin system has become popular when high sensitivity and specificity are desired.

BL21 is the most widely used host background and has the advantage of being deficient in both lon (1) and omp T proteases..

A common method for transformation of DNA plasmids into E. coli is the use of chemically competent cells.

The BL21(DE3) Electrocompetent Cells are the first to offer high efficiency cloning and high level protein expression in the same cell. Cloning efficiencies are increased 25-1,000 fold relative to other preparations of BL21 cells, which is
