Rabbit Monoclonal Antibody to Human HSP27 / HSPB1
Heat shock proteins (HSPs) are a group of highly conserved stress response proteins which primarily function as molecular chaperones, and are involved in a variety of biological processes including thermotolerance, inhibition of apoptosis, regulation of cell development and cell differentiation, as well as signal transduction. As a member of the chaperones, HSP27 appears in many cell types, especially all types of muscle cells, and is suggested to play an essential role in the differentiation of tissues. HSP27 has a characteristic and highly conserved amino acid sequence at the C-terminus, the so-called α-crystallin-domain which is important for the formation of stable dimers, and it is demonstrated that the oligomerization status is connected with the chaperone activity. HSP27 is also identified as an anti-apoptotic molecule. It interacts with the outer mitochondrial membranes and interferes with the activation of cytochrome c/Apaf-1/dATP complex and therefore inhibits the activation of procaspase-9 and procaspase-3. Furthermore, HSP27 also exerts functions in protecting actin filaments from fragmentation and the activation of the certain proteasome.
Human HSP27 / HSPB1. No cross-reactivity with human cell lysate ( 293 cell line ) in WB and ELISA.
Recombinant human HSP27 protein
Western blot: This antibody can be used at 1 - 2 μg/mL with the appropriate secondary reagents to detect human HSP27 in WB. Using a DAB detection system, the detection limit for human HSP27 is approximately 0.25 ng/lane under non-reducing conditions and 0.125 ng/lane under reducing conditionsELISA: This antibody can be used at 0.1 - 0.2 μg/mL with the appropriate secondary reagents to detect human HSP27. The detection limit for human HSP27 is approximately 0.00245 ng/well
This antibody was obtained from a rabbit immunized with purified, human cell-derived, recombinant human HSP27.
