WebCells containing pLysS produce a small amount of T7 lysozyme. These strains are used to suppress basal expression of T7 RNA polymerase prior to induction, thus stabilizing recombinants encoding particularly toxic proteins. Genotype F – ompT hsdSB (rB- mB-) gal dcm (DE3) pLysS (CmR) Packaging 40 μL Features and Benefits WebC41(DE3), C43(DE3), C41(DE)pLysS, and C43(DE3) pLysS, as chemically competent cells, as indicated. Expression Recovery Medium is also available separately. 24-reaction kits are multiples of the 12 reaction kit, 2 × 12 reactions. Which OverExpress cell strain should I use? It is di˜ cult to predict which of the four OverExpress will work
