E. coli BL21
It is an exemplary host for the expression of recombinant proteins. As an E. coli B strain, it further lacks the major protease, encoded by the lon gene, catalyzing the endoproteolytic cleavage of damaged and recombinant proteins in the cell
大肠杆菌 BL21
| 订购信息 | E. coli BL21: E. coli B F-, ompT, hsdS (rB-, mB-), gal, dcm. |
| 应用 | Bacterial strain for the expression of GST fusion protein |
| 基因型 | The BL21 strain is derived from E. coli B. The genotype is F-, ompT, hsdS (rB -, mB -), gal, dcm |
| 生长条件 | Resuspend lyophilized cultures in 1 ml of LB medium*. Grow overnight at 37°C before plating onto LB agar plates |
| 储存条件 | -20°C, Mix equal volumes of stationary phase culture (grown in LB medium) and glycerol. Store at -70°C. Revive frozen glycerol stocks of BL21 by streaking onto LB agar plates |
| 用途 | The protease-minus nature of BL21 makes it useful as an expression host. Since BL21 does not transform well, use an alternate strain for cloning and maintenance of the vector |

It is an exemplary host for the expression of recombinant proteins. As an E. coli B strain, it further lacks the major protease, encoded by the lon gene, catalyzing the endoproteolytic cleavage of damaged and recombinant proteins in the cell
- A protease-deficient E. coli host strain for optimal expression of recombinant proteins
- High-level expression of a variety of recombinant proteins
- Defective in E. coli strain B, and wild-type restriction systems to permit high efficiency transformation with unmodified plasmid DNA
- Verified by RAPD fingerprint analysis using Ready-To-Go RAPD Analysis Kit
- Provided in lyophilized form
Well suited for use with the GST Gene Fusion System, E. coli BL21 is an exemplary host for the expression of recombinant proteins (1). As an E. coli B strain, it further lacks the major protease, encoded by the lon gene, catalyzing the endoproteolytic cleavage of damaged and recombinant proteins in the cell (2).
