Competent cells for transformation
LGC, Biosearch Technologies offers the best performance, value, and convenience in competent cells for cloning and expression. Our chemically competent cells offer an unmatched value for routine cloning, and our electrocompetent cells provide the highest possible efficiency for difficult cloning and library construction.
See our Custom Competent Cell Services page to learn how you can receive the high-quality cells in the exact format you need, when you need them. Custom dispensing is available in tubes or 96-well plates, for your strain or ours.
ISO 13485 Certified with 10+ years of manufacturing excellence
Our competent cells must pass strict QC specifications for transformation efficiency and antibiotic resistance.
Every lot of cells is tested to ensure the cells meet our guaranteed transformation efficiencies. Cells are also tested for resistance to a panel of antibiotics by plating mock-transformed cells on antibiotic plates. Common antibiotic panel includes: kanamycin, carbenicillin (ampicillin), streptomycin, tetracycline, gentamycin and chloramphenicol.
