Recombinant E.coli DnaK Chaperone Hsp70, Co-chaperone with DnaJ (508-638)

Cat. No.: DnaK-316
Product Overview: Recombinant DNAK was overexpressed in E. coli and purified to apparent homogeneity by using conventional column chromatography techniques (132 aa, 14.6 kDa). Additional amino acid(Met) is attached at N- terminus.
Description: DnaK, originally identified for its DNA replication by bacteriophage l in E. coli is the bacterial hsp70 chaperone. This protein is involved in the folding and assembly of newly synthesized polypeptide chains and in preventing the aggregation of stress-denatured proteins. Dnak(residues 508-638) of the substrate binding domain is a-helical and appears to act as a lid covering the substrate binding cleft.
Source: E.coli.
Formulation: Liquid. In 25 mM Tris-HCl buffer (pH 7.5) containing 100 mM NaCl, 1 mM DTT, 10% glycerol.
Molecular Weight: 14.6 kDa (132aa).
Purity: > 95% by SDS – PAGE.
Concentration: 1 mg/ml (determined by Bradford assay).
