GroES protein is the co-chaperonin of GroES in E. coli and assists protein folding. GroEL mediated folding requires the co-chaperonin GroES which is essential for viability. GroES is composed of a single heptameric ring of 10kD subunits that binds to the ends of the GroEL cylinder. GroES gene was amplified by PCR from E. coli and cloned into an expression vector. This protein was overexpressed in E. coli and was purified by using conventional chromatography techniques.
Catalog #G8976-07
Recombinant GroES produced in E. coli is a single, non-glycosylated polypeptide chain containing 97 amino acids and having a molecular mass of 10.4kD.
Storage and StabilityMay be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add 0.1% HSA or BSA, aliquot and store at -20°C. Aliquots are stable for at least 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer..
