Description

ECOS™ 21 (BL21) | FYE207-5VL/FYE207-40VL | AGTC

 

This strain provides high levels of protein expression. This strain carries the lambda DE3 lysogen, which expresses T7 RNA polymerase from the lacUV5 promoter by isopropyl-1-thio-ß-D-galactopyranoside (IPTG) induction. The transformation efficiency of BL-21 is usually low, so the 6 minute/ heat shock cold plating protocol is recommended if high efficiency is desired.
 
 
Features
  • lack of Lon and Omp proteases allows high-level protein expression and accumulation
  • Easy gene induction

Applications

  • IPTG induced gene expression in E. coli
  • Ideal for high-level expression of non-toxic recombinant protein expression using T7-based expression vectors
  • Subcloning
