For reliable transformation results in cloning or protein expression workflows, researchers need high-performance competent cells tailored to their needs. GoldBio features both chemically competent and electrocompetent E. coli strains optimized for cloning, expression, and specialized applications like phage display.

Options include common laboratory strains such as DH5α and DH10B, available under the GB5-alpha™ and GB10B™ labels, as well as expression-ready strains like BL21 (DE3) and DL39 (DE3). GoldBio also offers control plasmids and recovery media to complete your workflow and streamline transformation efficiency.
