Protocol Available protocols: Western Blotting, Immunohistochemistry (Paraffin), Immunofluorescence (Immunocytochemistry) Specificity / Sensitivity HSP27 (G31) Mouse Monoclonal Antibody detects endogenous levels of total HSP27 protein. This antibody does not cross-react with other heat shock proteins. Non-specific staining was observed in red blood cells of few tissues by immunohistochemistry. Species Reactivity: Human, Monkey Source / Purification Monoclonal antibody is produced by immunizing animals with full length HSP27 protein. Background Heat shock protein (HSP) 27 is one of the small HSPs that are constitutively expressed at different levels in various cell types and tissues. Like other small HSPs, HSP27 is regulated at both the transcriptional and posttranslational levels (1). In response to stress, the HSP27 expression increases several-fold to confer cellular resistance to the adverse environmental change. HSP27 is phosphorylated at Ser15, Ser78, and Ser82 by MAPKAPK-2 as a result of the activation of the p38 MAP kinase pathway (2,3). Phosphorylation of HSP27 causes a change in its tertiary structure, which shifts from large homotypic multimers to dimers and monomers (4). It has been shown that phosphorylation and increased concentration of HSP27 modulates actin polymerization and reorganization (5,6).
