LGC Biosearch Technologies E. cloni EXPRESS BL21(DE3) Electrocompetent Cells, 12 RxnsGet better colony counts for routine protein expression with any E. coli T7 expression vector, with this high-efficiency BL21(DE3) strain.
Supplier: LGC Biosearch Technologies 603001
LucigensE. cloniEXPRESS BL21(DE3) Electrocompetent Cells are the first to offer high efficiency cloning and high level protein expression in the same cell. Cloning efficiencies are increased 25-1,000 fold relative to competitors preparations of BL21 cells, which is essential for construction of complex expression libraries. The unprecedented transformation efficiency ofE. cloniEXPRESS Electrocompetent Cells (>5 10^9cfu/g) eliminates the need for plasmid transfer from the cloning strain to the expression strain, saving days of work in a typical cloning and expression experiment. E. cloni EXPRESS cells are also available as chemically competent cells. With a transformation efficiency of >1 10^7 cfu/g and very economical prices, EXPRESS Chemically Competent Cells offer superior value for everyday protein expression work.
