Weitere Details:: The heat-shock proteins (HSPs) belong to a larger group of polypeptides, the stress proteins, that are induced in various combinations in response to environmental challenges and developmental transitions. Synthesis of the small (27kD) HSP has been shown to be correlated with the acquisition of thermotolerance. The deduced 199aa HSP27 protein shows sequence similarity to mammalian alpha-crystallins. Approximately 20% of its residues are susceptible to phosphorylation. The HSP27 gene, which is mapped to 7q11.23 and has 3 exons, produced a 2.2kb transcript in an in vitro transcription assay. Decreasing ROS in cells expressing mutant huntingtin, HSP27 protects cells against oxidative stress. In other words, HSP27 is a suppressor of polyglutamine (polyQ)-mediated cell death. Furthermore, MAPKAPK5 is a major stress-activated kinase that can phosphorylate HSP27 in vitro. Applications: Suitable for use in Western Blot and Immunohistochemistry. Other applications not tested. Recommended Dilution: Western Blot:1ug/ml Immunohistochemistry (paraffin):1-2ug/ml Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for at least 12 months.
