Description

The HSP27 Antibody Kit provides an economical means to evaluate the activation status of the HSP27 protein. The kit contains enough primary antibody to perform two western blot experiments per primary antibody.

Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA, 50% glycerol and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

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).

    Western blot analysis of extracts from HeLa cells (lane 1) or HSP27 knock-out cells (lane 2) using HSP27 (G31) Mouse mAb #2402 (upper), and α-Actinin (D6F6) XP® Rabbit mAb #6487 (lower). The absence of signal in the HSP27 knock-out HeLa cells confirms specificity of the antibody for HSP27.
