| 背景 | Meprins are multimeric proteases composed of alpha and beta subunits, which are members of the astacin family of zinc endopeptidases (1, 2). Both subunits form disulfide-linked homo- or heterooligomers, which are also referred to as Meprin A (composed of alpha subunits with or without beta subunits) and Merpin B (composed of beta subunits only) (3). Although the two subunits share 42% amino acid (aa) sequence identity, they differ significantly in their oligomeric structure, post-translational processing and subsequently cellular location, and substrate and peptide bond specificity (4). The 701 aa sequence of human Merpin beta subunit precursor consists of a signal peptide (aa 1 to 21), a pro region (aa 22 to 61), and a mature chain (aa 62 to 701) containing catalytic (aa 62 to 259), MAM (aa 260 to 429), MATH (aa 430 to 585), EGF-like (aa 604 to 644), transmembrane (aa 653 to 673), and cytoplasmic (aa 674 to 701) domains. |

Detection of Human and Mouse Meprin beta Subunit/ MEP1B by Western Blot. Western blot shows lysates of human intestine tissue and mouse intestine tissue. PVDF membrane was probed with 1 µg/mL of Rat Anti-Human/Mouse Meprin beta Subunit/MEP1B Monoclonal Antibody (Catalog # MAB28951) followed by HRP-conjugated Anti-Rat IgG Secondary Antibody (Catalog # HAF005). A specific band was detected for Meprin beta Subunit/MEP1B at approximately 97 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1. | |
Meprin beta Subunit/MEP1B in Human Intestine. Meprin beta Subunit/MEP1B was detected in immersion fixed paraffin-embedded sections of human intestine using Human/Mouse Meprin beta Subunit/MEP1B Monoclonal Antibody (Catalog # MAB28951) at 1 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Rat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS017) and counterstained with hemotoxylin (blue). Specific staining was localized to the Brush border of epithelial cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections. This application has not been tested in mouse samples |
