Detection of Mouse MSP/MST1 by Western Blot. Western blot shows lysates of mouse liver tissue. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Mouse MSP/MST1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6244) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for MSP/MST1 at approximately 96 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Immunohistochemistry

MSP/MST1 in Mouse Liver. MSP/MST1 was detected in perfusion fixed frozen sections of mouse liver using Sheep Anti-Mouse MSP/MST1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6244) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue). Specific staining was localized to hepatocytes.

Background: MSP/MST1

MSP (Macrophage stimulating protein 1; also hepatocyte growth factor-like protein) is an 80-95 kDa member of the peptidase S1 family of proteins. Although it is expressed principally by hepatocytes, it can also be induced in cells such as renal tubular epithelium. MSP has multiple targets, and as such, has multiple effects. It stimulates macrophage motility and phagocytosis, promotes keratinocyte and renal tubular cell proliferation, and depresses myeloid progenitor cell replication. Mouse proMSP is 698 amino acids (aa) in length. It contains one PAN (carbohydrate-binding) site (aa 19-105), four consecutive kringle domains (110-457) and an inactive peptidase S1 region (aa 489-714). An intrachain disulfide bond exists between Cys477 and Cys593 that becomes an interchain bond following protease cleavage between Arg488 and Val489. This creates a mature heterodimer containing a 45-57 kDa alpha -chain, and a 30-35 kDa beta -chain. Mouse proMSP shares 80% and 93% aa identity with human and rat proMSP, respectively.
