Scientific Data Images for HSP27 Antibody

Knockout Validated: HSP27 Antibody [NBP2-24533]

Knockout Validated: HSP27 Antibody [NBP2-24533]

Knockout Validated: HSP27 Antibody [NBP2-24533] - Lysates of HeLa human cervical epithelial carcinoma parental cell line and HSP27 knockout (KO) HeLa cell line. PVDF membrane was probed with 2 ug/mL of Rabbit Anti-Human HSP27 Polyclonal Antibody (Catalog # NBP2-24533) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (catalog number HAF008). Specific band was detected for HSP27 at approximately 27 kDa (as indicated) in the parental HeLa cell line, but is not detectable in the knockout HeLa cell line. This experiment was conducted under reducing conditions.
Western Blot: HSP27 Antibody [NBP2-24533]

Western Blot: HSP27 Antibody [NBP2-24533]

Western Blot: HSP27 Antibody [NBP2-24533] - Analysis of HSP27 in human skeletal muscle lysate using 1) preimmune sera at 1:5000 and 2) peptide affinity purified HSP27 antibody at 2.0 ug/mL. Goat anti-rabbit Ig HRP secondary antibody and PicoTect ECL substrate solution were used for this test.
Immunohistochemistry-Paraffin: HSP27 Antibody [NBP2-24533]

Immunohistochemistry-Paraffin: HSP27 Antibody [NBP2-24533]

Background: HSP27

Hsp25 is the mouse homologue of the human Hsp27 protein, a member of the small heat shock protein family comprised of a diverse group of proteins from approx. 15 to >30kDa(1). The basic structure of most sHsps is a homologous and highly conserved amino acid sequence, with an alpha-crystallin-domain at the C-terminus and the WD/EPF domain at the less conserved N-terminus. This N-terminus is essential for the development of high molecular oligomers (2, 3). Hsp27-oligomers consist of stable dimers formed by as many as 8-40 Hsp27 protein monomers (4). The oligomerization status is connected with the chaperone activity: aggregates of large oligomers have high chaperone activity, whereas dimers have no chaperone activity (5). HSP27 is localized to the cytoplasm of unstressed cells but can redistribute to the nucleus in response to stress, where it may function to stabilize DNA and/or the nuclear membrane. It can be rapidly phosphorylated in response to physiological stimuli relevant to the cell type examined. Thus, hsp27 has been suggested to be an important intermediate in second messenger mediated signaling pathways (6). Other functions include chaperone activity (as mentioned above), thermotolerance in vivo, inhibition of apoptosis, and signal transduction. Specifically, in vitro, it acts as an ATP-independent chaperone by inhibiting protein aggregation and by stabilizing partially denatured proteins, which ensures refolding of the HSP70 complex. Hsp27 is also involved in the apoptotic signaling pathway because it interferes with the activation of cytochrome c/Apaf-1/dATP complex, thereby inhibiting the activation of procaspase-9. It is also hypothesized that hsp27 may serve some role in cross-bridge formation between actin and myosin (7). And finally, Hsp27 is also thought to be involved in the process of cell differentiation. The up-regulation of Hsp27 correlates with the rate of phosphorylation and with an increase of large oligomers. It is possible that Hsp27 may play a crucial role in termination of growth (8).
