CELLS C41 12 RXNSEach OverExpress kit contains Electrocompetent Cells in SOLO packaging (1 transformation per tube), Expression Recovery Medium (lactose minus), pUC19 Positive Control Plasmid, pAVD10 Verification Plasmid, and complete protocols. E. coli BL21(DE3) strains, like E. cloni EXPRESS Competent Cells provide reliable expression of many genes cloned into T7 expression vectors (e. g.., pET or pSMART cDNA vectors). However, in some cases expression is minimal or
