The ABLE C strain and the ABLE K strain help solve issues associated with toxic clones. The ABLE C strain reduces the copy number of ColE1-derived plasmids, e.g. pUC and pBluescript, by approximately 4-fold (compared to the XL1-Blue strain) and the ABLE K strain reduces the copy number of these plasmids approximately 10-fold.

The AdEasy system saves you a month of work over traditional methods by producing the recombinant adenoviral plasmid by homologous recombination in E. coli. 

ArcticExpress Competent Cells are engineered to address the common bacterial gene expression hurdle of protein insolubility. These cells are derived from the high-performance Stratagene BL21-Gold competent cells, enabling efficient high-level expression of heterologous proteins in E. coli.

In addition to enhancing protein solubility, we have combined our cold-adapted technology with our premiere BL21-CodonPlus competent cells to further increase your chances of protein expression success.

The AdEasy system saves you a month of work over traditional methods by producing the recombinant adenoviral plasmid by homologous recombination in E. coli. The AdEasy XL system includes BJ5183 cells pre-transformed with the pAdEasy-1 plasmid, this feature dramatically decreases background caused by the non-recombinant shuttle plasmid.

BL21-CodonPlus strains are engineered to contain extra copies of genes that encode the tRNAs that most frequently limit translation of heterologous proteins in E. coli. They are ideal for difficult protein expression, especially when codon bias is a problem.
