HI-Control BL21(DE3) Chemically Competent Cells (SOLOS)

Product Description

Induce high-level protein expression from T7 promoters with tight control over leaky expression, using this strain containing a LacI repressor.

The HI-Control BL21(DE3) cells are a derivative of BL21(DE3) with improved control over target gene expression. BL21(DE3) is the T7 host strain most commonly used for expression of cloned genes from the bacteriophage T7 promoter.
