PA3-013 detects heat shock protein 90 (HSP90) from human, monkey, mouse, sheep (adrenal) and rat tissues and cells. This antibody does not detect HSP84. PA3-013 has been successfully used in Western blot, immunofluorescence, immunohistochemistry (paraffin) and immunoprecipitation procedures. By Western blot, this antibody detects an ~86 kDa protein representing HSP86 from HeLa cell lysate. Immunofluorescence staining of HSP86 in HeLa cells with PA3-013 yields a pattern consistent with cytoplasmic staining. Immunoprecipitation experiments with this antibody suggest that HSP86 exists primarily as homodimers in HeLa cells. Furthermore, the antibody is capable of precipitating HSP86 that is complexed with other proteins such as the aryl hydrocarbon (Ah) receptor. The PA3-013 immunogen is a synthetic peptide corresponding to residues P(2) E E T Q T Q D Q P M(12) of mouse HSP86. The N-terminal regions of HSP84 and HSP86 show the largest difference in amino acid sequence.

Heat shock proteins (HSP) are expressed in response to various biological stresses, including heat. HSP90 is a 90 kDa protein that is induced under stress conditions, but is also one of the most abundant cellular proteins found under non-stress conditions. HSP90 has been found to be associated with a number of other intracellular proteins, including steroid receptors, actin, tubulin, Ah receptor, and some kinases. Studies have shown that murine HSP90 exists as two forms, HSP84 and HSP86, coded by related but separate genes, with 86% homologous amino acid sequences. These forms are analogous to the two forms of human HSP90, HSP89 beta and HSP89 alpha. In an unstressed mouse fibroblast, the basal level of HSP84 is found to be double that of HSP86. However, after heat shock, HSP86 shows a greater increase. Studies also suggest that upon cellular differentiation, the level of HSP86, but not HSP84, decreases. HSP84 and HSP86, which may be subject to estrogenic regulation, have been found as components of the non-DNA binding form of mouse glucocorticoid receptor, but dissociated from the transformed DNA-binding form.
