GroEL protein is the major heat shock protein of E.coli and belongs to the chaperonin(HSP60) family. GroEL protein prevents misfolding of proteins and promotes the refolding and proper assembly of unfolded polypeptiedes generated under stress condition. GroEL 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. Recombinant GroEL produced in E. coli is a single,non-glycosylated polypeptide chain conjtaining 548 amino acids and having a molecular mass of 57.3kD.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage, add 0.1% HSA or BSA, aliquot and store at -20C. Aliquots are stable for at least 6 months at -20C. 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.
