Heat shock protein (HSP) 27 is one of the small HSPs that are constitutively expressed at different levels in different cell types and tissues (this protein has also been referred to as the Estrogen-Regulated 24 kDa protein, hsp25 and hsp28). Like other small heat shock proteins, HSP27 is regulated at both the transcriptional and post-translational level. In response to stress, the expression level of HSP27 increases several-fold to confer cellular resistance to the adverse environmental change. The common functions of sHsps are chaperone activity, thermotolerance, inhibition of apoptosis, regulation of cell development, and cell differentiation. They also take part in signal transduction. The HSP27 gene has 3 exons. The mouse Hsp25 gene was mapped to chromosome 5 in a region homologous to 7q in the human. They also mapped the mouse Hsp105 gene to chromosome 5 but suggested that the human homolog is probably on 13q, not chromosome 7. HSP27 plays a major role in the increased thermal resistance acquired by cells after exposure to HSP inducers. The level of HSP27 phosphorylation is significantly elevated after exposure of cells to heat shock, sodium arsenite, IL-1 and TNF-a. MAPKAPK2 and MAPKAPK3 are both activated by these conditions and can phosphorylate HSP27 on serine residues Anti-HSP27 Antibody is ideal for investigators involved in Signaling Proteins, Cell Stress & Chaperone Proteins, Cancer, Cellular Stress, and p38 Pathway research.

This HSP27 monoclonal antibody was produced by repeated immunizations with a prokaryotic recombinant protein corresponding to the full length human hsp27 protein.

Application Note

This protein A purified monoclonal antibody against human Hsp27 has been tested for use in immunoblotting and ELISA and is suitable in immunoprecipitation, immunohistochemistry, and immunocytochemistry.  The antibody recognizes a 27 kDa band corresponding to hsp27 in cell lysates from breast carcinoma.    Both frozen sections and paraffin embedded material can be used for immunocytochemistry and immunohistochemistry.


This protein A purified mouse monoclonal antibody reacts specifically with HSP27 in human tissues and cell lines.  MCF-7 cells are recommended as a positive control.  Cross reactivity with hsp27 from other mammalian sources is likely.  No cross reactivity occurs with HSP70, HSP90 or HSP104.
