Product datasheet Anti-MASP2 antibody ab65895 1 Image Overview Product name Anti-MASP2 antibody Description Rabbit polyclonal to MASP2 Specificity ab65895 recognizes full-length MASP2 and the Map19 form, but not MASP1 or MASP3. We have a range of domain specific antibodies for this target. For a full list please see all MASP2 antibodies. Tested applications WB Species reactivity Reacts with: Human Immunogen A synthetic peptide based on the end of the first CUB domain, beginning of the EGF-like domain of human MASP2.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user. Application Abreviews Notes WB Application notes WB: 1/1000 when using colorimetric substrates such as BCIP/NBT, and 1/5000 for chemiluminescent substrates. Detects a band of approximately 76 kDa (predicted molecular weight: 76 kDa). 1 Not yet tested in other applications. Optimal dilutions/concentrations should be determined by the end user. Target Relevance MASP2, MBL associated serine protease 2, is a serum protease that plays an important role in the activation of the complement system via mannose-binding lectin (MBL). Binding of MBL to carbohydrate groups triggers MASP2 activation by auto-catalytic cleavage which leads to cleavage of C2 and C4, leading to their activation and to the formation of C3 convertase. MASP2 also binds to L-Ficolin and H-Ficolin, and when the complex binds pathogens the MASP is activated. Low MBL levels in serum are associated with increased susceptibility to infection, and an Asp105Gly mutation in MASP2 is associated with low MASP2 levels in serum. Reduced functional levels of MBL are also postulated to be associated with generation of autoantibodies in systemic lupus erythematosus, acting through a decreased clearance of apoptotic material. A truncated form of MASP2 that constitutes the amino 185 residues, Map19 is also a component of the MBL-MASP-1 complex.
