Heat shock protein 70 (Hsp70) from bovine brain has been used as a protein standard in Western blotting to check levels of the Hsp70 family proteins in honey bees after heat exposure. It has been used as a standard for the quantification of HSP70, obtained from liver sections of rats, by ELISA (enzme-linked immunosorbent assay).

Biochem/physiol Actions

HSPs (heat shock proteins) are needed for protein folding, protein assembly, protein aggregation and protein transport. They help in maintaining cellular homeostasis and offer cytoprotective effects. Hsp70 is associated with the protective effects on rat myocardial cells in presence of heat stress. Similarly, it offers neuro-protection from oxygen-glucose deprivation injury.

Physical form

Contains Tris buffer salts.
