HSP-70 Cofactor (HSP24) E.Coli (Recombinant)

Synonyms

HSP24, HSPB25.3, HSP-70 Cofactor, Protein grpE, Heat shock protein B25.3, grpE, b2614, JW2594.

GrpE , co-chaperone of E. coli, participates actively in the response to hyperosomotic and heat shock by preventing the aggregation of stress-denatured proteins in association with DnaK. This protein is the nucleotide exchange factor for DnaK and may function as a thermosensor. Several rounds of ATP-dependent interactions between DnaJ, DnaK and GrpE are required for fully efficient folding.

Description

GrpE Recombinant produced in E. coli is a single, non-glycosylated polypeptide chain containing 197 amino acids and having a molecular mass of 21.8 kDa. The GrpE is purified by proprietary chromatographic techniques.

Source

Escherichia coli

Physical Appearance

Sterile Filtered colorless solution.

Formulation

The HSP24 protein solution contains 20mM Tris-HCl pH-8 and 0.1M NaCl.

Stability

GrpE although stable 4°C for 4 weeks, should be stored desiccated below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
