BL21 (DE3) Competent Cells
Cat# BB-X0052 (100 µl X 5 Vials)
Description: Highly efficient (106 – 107cfu per µg DNA) BL21 (DE3) competent cells are used to transform ligation mixture.
Be extremely gentle when working with competent cells. Competent cells are highly sensitive to changes in temperature or mechanical lysis caused by pipetting. Transformation should be started immediately following the thawing of the cells on ice.
Mix by swirling or tapping the tube gently, not by pipetting or vortexing.
Storage: -80oC (Recommended).
Exp. Date: 2 months upon receiving at proper storage condition as mentioned in datasheet.
