背景 | HTRA1 is a member of the mammalian HTRA (high temperature requirement A) serine protease family. The E. coli HTRA homolog functions as a chaperone-protease and is essential for bacterial survival at temperatures above 42 °C (1). Among the four mammalian HTRA proteins, HTRA1, -3 and -4 are secreted while HTRA2 is localized in mitochondria. HTRA1 contains an N-terminal insulin-like growth factor binding protein (IGFBP) domain, a Kazal-type trypsin inhibitor motif, and C-terminal trypsin-like protease and PDZ domains (2). It is involved in several pathologies including Alzheimer’s disease (3), rheumatoid arthritis (4), osteoarthritis (5) and age‑related macular degeneration (6), although the mechanisms by which HTRA1 exerts its effects are not clear. HTRA1 also has properties of a tumor suppressor protein, which makes it a target for cancer therapy (7). In addition HTRA1 is known to regulate the TGF-beta signaling pathway and bone mineralization (8, 9). rhHTRA1 lacks the N-terminal IGFBP and Kazal-like domains, but retains the serine protease and PDZ domains. |

Detection of Human HTRA1/PRSS11 by Western Blot. Western blot shows lysates of JAR human choriocarcinoma cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human HTRA1/PRSS11 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2916) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for HTRA1/PRSS11 at approximately 50 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1. | |
Detection of Human HTRA1/PRSS11 by Simple WesternTM. Simple Western lane view shows lysates of JAR human choriocarcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for HTRA1/PRSS11 at approximately 54 kDa (as indicated) using 10 µg/mL of Sheep Anti-Human HTRA1/PRSS11 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2916) followed by 1:50 dilution of HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system. |
