Phage Display TG1 Chemically Competent E. coli Cells

TG1 chemically competent cells can be used for phage display, antibody phage display library construction and screening, cloning, sub-cloning, and protein expression. lacI^q gene encoded on F’ episome allows tight regulation of expression vectors that contain an E. coli promoter under control of a lac operator sequence, like T5, tac, trc.

TG1 chemically competent cells are supplied as a pack of 10 convenient single use aliquots (100 µl /tube).

Electrocompetent TG1 E.coli cells are also available. 

Bulk quantities and custom packaging are available at very competitive prices for all Competent Cells.
