Gold Biotechnology Inc DL39 DE3 Comp E coli Cells

GoldBio s 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
