Endura™ Competent Cells include Control DNA and Recovery Medium, and are packaged as SOLOs (1 transformation per tube) or DUOs (2 transformations per tube) as indicated. Endura Electrocompetent cells are provided in DUOs format only. Recovery Medium is also available separately. The specified transformation efficiencies are with pUC DNA, unless indicated otherwise.

PLEASE NOTE: Bulk quantities (10 times larger than the largest retail package size below) and/or custom packaging are available at very attractive prices for all Lucigen Competent Cells. Please contact Lucigen.

NOTE:  Transformation of Endura Electrocompetent Cells with GeCKO lentiviral libraries may require extra Recovery Medium.  The Zhang lab protocol (available from Addgene) recommends ~2 mL of Recovery Medium per transformation.  Lucigen Endura kits provide 1 mL of Recovery Medium per transformation.  Order extra Recovery Medium here!
