HSP27 Antibody - BSA Free

Knockout Validated: HSP27 Antibody [NBP1-75477] - Western blot shows 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 # NBP1-75477) 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.

Background

Heat shock protein 27 is a molecular chaperone involved in protection of cells during cellular stress events. The activity of HSP27 protects from apoptotic events caused by heat shock and other distress. Immunohistochemical detection of HSP27 has been suggested as a qualitative biomarker for colorectal cancer. It is also highly expressed in lung cancer, cerebral inflammation, ischemia-reperfusion injury, and glaucoma. Interestingly, HSP27 overexpression can counteract the activity of multi-drug resistance proteins in breast cancer. Polyphenols downregulate the expression of HSP27, as well as many antioxidant enzymes, resulting in susceptibility to stress and damage.
