“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). Thanks, Wei, Pharmaceutical Researcher.

“Lucigen’s cells ROCK! Few, if any, companies or individual laboratories make cells with as high efficiencies.”
- Dr. Douglas Crawford, University of Miami, Miami, FL

"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! Sincerely, Dr Jason LeBlanc"
