Perform plasmid rescue for transposition mutants created with the EZ-Tn5 Transposome Kits.
Clone and subclone with high efficiency, chemically competent DH5-alpha cells.
Create large phage display libraries with high efficiency cells recommended for peptide display.
Clone unstable and toxic sequences in standard plasmids, with high efficiency.
Clone and maintain unstable or repetitive sequences and lentiviral libraries with high efficiency. Ideal for GeCKO CRISPR library transformation.
Clone large inserts in standard plasmids, and control copy number of CopyControl vectors. EPI300 Electrocompetent cells are recommended for Gibson Assembly® reactions.
Clone and sub-clone with high-efficiency, recA, endA competent cells.
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.
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.
