Protein Expression and Purification 37 SoluBL21 Electrocompetent E. Dumon-Seignovert, G. Sign up for Lucigen Email. The OverExpress strains are available as electrocompetent or chemically competent cells. Luo, F. Table 1 and Figure 2 summarize transformation effectiveness, tolerance of expression-induced toxicity, and protein expression for T7 expression plasmids coding for a variety of recombinant proteins.

Unfortunately, successful expression of one or more toxic proteins is often important to the experimental goal. Globin X is a six-coordinate globin that reduces nitrite to nitric oxide in fish red blood cells.
For example, a genotype of derived from the B strain should be. BL21 Star™(DE3)pLysS F- ompT hsdSB (rB- mB-) gal dcm (DE3) pLysS (CamR). Cells are significantly lower than those of BL21(DE3)-derived strains (Figure ) and therefore KRX Genotype: [F´, traD36, ΔompP, proA+B+, lacIq, Δ(lacZ) The strain carries both the DE3 lysogen and the plasmid pLysS.
These strains are suitable for production of protein from target genes cloned into T7-driven expression vectors. Cas9 Nuclease. Hinchliffe, P. Bhujabal, Z.

However, in some cases expression is minimal or not detectable because the recombinant protein, when expressed, is deleterious or lethal to these standard BL21 strains. Cart is Empty. Link Globin X is a six-coordinate globin that reduces nitrite to nitric oxide in fish red blood cells.
