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.[1]
BL21(DE3)Chemically Competent Cells has been used for the transformation and expressionof protegrin-1 (PG1) peptides.[2]
to express 6His-TEVsite-Hs ARF1 (17-181)-Q71L in pHis2 vector.[3][1]
Features and Benefits
a transformation efficiency of >1 × 107 cfu/μg.
economical prices
offering superior value for everyday protein expression work.
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
Citrate, α-ketoglutarate and succinate are TCA cycle intermediates that also play essential roles in metabolic signaling and cellular regulation. These di- and tricarboxylates are imported into the cell by the divalent anion sodium symporter (DASS) family of plasma membrane transporters

The development and feasibility of a novel nanocrystalline yttria-stabilized-zirconia (nc-YSZ) cranial implant has been recently established. The purpose of what we now call "window to the brain (WttB)" implant (or platform), is to improve patient care by providing a technique

The celH gene from Clostridium thermocellum encodes a protein containing 900 residues and three components, including Cel5E, Lic26a, and carbohydrate-binding domains. Cel5E is a member of the glycoside hydrolase-5 family and is a bifunctional xylanase/cellulase enzyme. We targeted a semi-hydrophobic
BL21 Chemically Competent Cells come in aliquots for easy transformation with heat shock method, facilitating molecular biology experiments.
