General description

The BL21(DE3) Chemically Competent strains contain the phage T7 RNA polymerase gene linked to the IPTG-inducible promoter, for use with any expression plasmid containing the T7 promoter.

Genotype

F – ompT hsdSB (rB- mB-) gal dcm (DE3)

Application

The E. coli strain BL21 (DE3) has been used:

  • to express tau 2N4R isoform (aa1–441) and the truncated tau (aa1–421) using pET19b as expression vector.
  • BL21(DE3)Chemically Competent Cells has been used for the transformation and expressionof protegrin-1 (PG1) peptides.
  • to express 6His-TEVsite-Hs ARF1 (17-181)-Q71L in pHis2 vector.

Features and Benefits

  • a transformation efficiency of >1 × 107 cfu/μg.
  • economical prices
  • offering superior value for everyday protein expression work.

Other Notes

  • BL21(DE3) chemically competent cells
  • pUC 19 transformation control DNA
  • recovery medium for expression

Physiological aggregation of a recombinant enzyme into enzymatically active inclusion bodies could be an excellent strategy to obtain immobilized enzymes for industrial biotransformation processes. However, it is not convenient to recycle "gelatinous masses" of protein inclusion bodies from one reaction
