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 Escherichia coli.

•  Low growth temperatures enhance protein folding and solubility
•  Feature chaperonins Cpn60 and Cpn10 from psychrophilic bacterium Oleispira Antarctica
•  Correct for codon bias and enhance solubility at the same time
