Introduction
Escherichia coli Hsp31 (HchA) is a homodimeric member of the ThiI/DJ-1/PfpI superfamily which combines molecular chaperone and aminopeptidase activities. HchA uses temperature-induced exposure of structured hydrophobic domains to capture and stabilize early unfolding protein intermediates under severe thermal stress.
Description
hchA produced in E.Coli is a single, non-glycosylated polypeptide chain containing 303 amino acids (1-283 a.a.) and having a molecular mass of 33.3kDa.
hchA is fused to a 20 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile filtered colorless solution.
Formulation
The hchA contains (1mg/ml) 20mM Tris-HCl buffer (pH8.0), 20% glycerol 0.1M NaCl and 1mM DTT.
Stability
hchA E.Coli Recombinant although stable at 4°C for 1 week, should be stored below -18°C.
Please prevent freeze thaw cycles.
Purity
Greater than 95.0% as determined by SDS-PAGE.
