Competent Cells

The ABLE K strain help solve issues associated with toxic clones. The ABLE K strain reduces the copy number of these plasmids approximately 10-fold. This decreases the level of cloned protein product, increasing cell viability when protei... Read more...

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 strai... Read more...
