Phage Display SS320 Chemically Competent E. coli Cells | Amid Biosciences
The E. coli strain SS320 is a non-amber suppressor strain (sometimes called MC1061F′) prepared as high transformation efficiency (≥ 1 × 109 cfu/μg) chemically competent cells for phage display library screening. The SS320 strain harbors an episome that contains the F′ pilus that is required for bacteriophage entry to allow amplification of phage libraries. This episome also contains the tetracycline resistance gene, so cells should be grown in the presence of tetracycline to maintain the F′ pilus.
SS320 chemically competent cells are supplied as a pack of 10 convenient 100 µl per tube aliquots (sufficient for 20 reactions).
