Takara, 636766, Stellar™ Competent Cells

Stellar Competent Cells are anE. coliHST08 strain that provides high transformation efficiency. These cells can be used in a wide variety of applications-from preparation of cDNA and genomic libraries, to construction of longer-length genomic libraries, to subcloning, and even methylated DNA cloning. Stellar Competent Cells lack the gene cluster for cutting foreign methylated DNA (mrr-hsdRMS-mcrBCandmcrA), and are therefore useful for cloning methylated DNA. The cells can also be used for blue/white screening (i.e., α-complementation) when transformed with vectors containing thelacZαgene. This package includes 50 tubes of competent cells (100 μl/tube), SOC Medium and a pUC19 vector.
