Monoclonal Anti-Heat Shock Protein 70 antibody produced in mouse

A variety of environmental disruptions, such as a sudden increase in temperature, induce cells to rapidly synthesize a group of polypeptides known as heat shock (stress) proteins. Eukaryotic cells contain a multigene family that encodes several closely related 70 kD stress proteins (the HSP70 family) that differ in their intracellular location and regulation.These include four proteins: the constitutive (or cognate) HSP73, the stress-inducible HSP72 and the glucose regulated proteins grp78 (or BiP) and grp75.

Monoclonal Anti-Heat Shock Protein 70 (mouse IgG1 isotype) is derived from the BRM-22 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with purified bovine brain HSP70. Heat shock protein family A (Hsp70) member 1A (HSPA1A), is encoded by the gene mapped to human chromosome 6p21.33. It is widely expressed in all tissues. The encoded protein is characterized with an N-terminal ATPase domain of 45 kDa and a C-terminal substrate binding domain of 25 kDa.

By immunoblotting, the antibody localizes both the constitutive (HSP73) and inducible (HSP72) forms of HSP70. The antibody recognizes HSP70 from brain and other tissue. Immunofluorescent staining demonstrates a rapid and reversible accumulation of the HSP70 protein within the nucleus of heat-shocked (42 °C, 1 hour) human fibroblasts.

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Immunoprecipitation (1 paper)
Western Blotting (4 papers)

Monoclonal Anti-Heat Shock Protein 70 antibody produced in mouse has been used in:

• enzyme-linked immunosorbent assay (ELISA)
• immunoblot
• dot blot
• immunocytochemistry

The antibody titer of at least 1:5,000 was determined by immunoblotting using bovine brain extract.

Members of the HSP70 family play a major role in the folding, unfolding and translocation of polypeptides as well as in the assembly and disassembly of oligomeric protein complexes. In addition, several possible roles have been attributed to the HSP70 family of proteins, in the immune response. It has been shown that alcoholic liver disease is associated with intracytoplasmic accumulation of HSP70. HSP72 was found to increase dramatically in the brains of Alzheimer′s disease patient, and was localized exclusively in neuritic plaques and neurofibrillary tangles. HSP70 concentrates in nuclei during heat shock and returns to the cytoplasm when the shock is removed.
