85-2057-85　GroEL, Recombinant (Chaperonin 60, cpn60, Heat Shock Protein 60, HSP60) 1mg　G8976-01A1

特徴

• 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.
