BL21 (DE3) Chemically Competent E. coli Cells Size:10 x 50 μL The cocktail is EDTA freeGoldBios BL21 (DE3) Chemically Competent E. coli cells are are high efficiency cells, suitable for a wide variety of applications such as transformation and routine protein expression. BL21 (DE3) chemically competent cells feature a widely used host background, a T7 expression strain, and are deficient in both Ion (1) and ompT proteases. In addition, BL21 (DE3) cells are resistant to phage T1 (fhuA2) and are B strain. BL21 (DE3) chemically competent
