DL39 (DE3) Chemically Competent E. coli Cells M354 Transformation efficiency should be ≥8GoldBios DL39 (DE3) Chemically Competent E. coli cells are engineered with a T7 expression system to transform and express proteins in order to label residues such as phenylalanine or leucine. DL39 (DE3) Chemically Competent E. coli cells are deficient in the aromatic (TyrB), branched chain (JIvE), and aspartate (AspC) transaminases and are auxotrophic for aspartic acid, isoleucine, leucine, phenylananine, tyrosine, and valine residues.
