BL21(DE3) ΔserC Chemically Competent E.coli Cells for Protein Phosphorylation

$ 600.00

Amid Biosciences’ BL21(λDE3) ΔserC is an engineered strain where serC gene was deleted to reduce the intracellular levels of phosphoserine. The abundance of phosphoserine in E.coli cells interferes with a site-specific incorporation of non-natural analogs of phosphoserine or phosphothreonine into recombinant proteins. In E. coli, phosphoserine is synthesized from 3-phosphohydroxypyruvate by phosphoserine aminotransferase encoded by serC gene.

BL21(λDE3) ΔserC chemically competent E.coli cells are supplied as a pack of 10 convenient 100 μl/tube aliquots.  The transformation efficiency is ≥ 1x106 cfu/μg pBR322 plasmid DNA.

E. coli genotype: fhuA2 [lon] ompT gal (λ DE3) [dcm] ∆hsdS ΔserC

[λ DE3 = λ sBamHIo ∆EcoRI-B int::(lacI::PlacUV5::T7 gene1) i21 ∆nin5]
