“The TG1 cells I ordered worked great, and I really appreciate your efforts in getting me the cells in such a short time period. The cells have a super-high transformation efficiency [...] and I achieved a much bigger library than I was expecting (great news for me)."
Wei, Pharmaceutical Researcher.

"I have recently tried a sample pack of your Electrocompetent Cells for Phage Display (TG1, ER2738 and SS320). They worked absolutely great! I was quite impressed with the transformation efficiency. No other cells I've tested have come close to this!"
Dr. Jason LeBlanc"

"Lucigen’s TGI cells are perfect for phage library construct for their high transformation efficiency."
