Recombinant human HSP70/HSPA1A protein

Hsp70 is a human heat shock protein. Hsp70 is an important part of the cell's machinery for protein folding, and help to protect cells from stress. In most species, there are many proteins that belong to the hsp70 family. Some of these are only expressed under stress conditions, while some are present in cells under normal growth conditions and are not heat-inducible. They can be found in different cellular compartments (nuclear, cytosolic, mitochondrial, endoplasmic reticulum, etc...) . Recombinant human Hsp70, fused to His-tag at N-terminus, was expressed in E. coli and purified by using conventional chromatography techniques.
