The monoclonal antibody 4H2A9 reacts with the CCP1 domain, which is shared by MASP-1, MASP-3 and MAp-44. In total 5 MASP proteins have been identified (MASP-1, MASP-2, MASP-3, MAp19 and MAp44) which are encoded by 2 genes. The MASP-2 gene gives rise to MASP2 and MAp19 due to alternative splicing, whereas the MASP-1 gene encodes a primary transcript which can be spliced to three different mRNAs coding for MASP-1, MASP-3 and MAp44 having molecular weights of 88, 89 and 44kDa, respectively. On the protein level MASP-1 and MASP-2 are shown to be responsible for complement activation through proteolytic cleavage of C2 and C4, whereas MASP-3 has been suggested to inhibit the generation of the C3 convertase. So far the role of the truncated proteases MAp44 and Map19 remain unknown. The monoclonal antibody 4H2A9 is suitable for western blotting and immunoprecipitation experiments. Moreover, the antibody can be used in immunoassays detecting MASP-1, MASP-3 and/or MAp44.

Immuno assays

For immuno assay dilutions to be used depend on detection system applied. It is recommended that users test the reagent and determine their own optimal dilutions. The typical starting working dilution is 1:50.

  • New Human Complement Pathway Assays
    We are very proud of our newly developed human classical and alternative complement pathway assays. They are produced in response to a growing demand for quantitative investigation of complement inhibitors or regulators at lower sample dilutions. This development aims to address the issue of false negative results, enabling more accurate and reliable analysis of complement… Read more: New Human Complement Pathway Assays
  • Navigating the pitfalls in complement analysis
    Our colleague Erik Toonen shared his experience on how to analyze complement at the Complement-based Drug Development Summit in Boston in September 11-13th, 2023. He showed valuable insights on analyzing complements. For accurate complement analysis, it is important that not only the correct technique is used but also that pre-analytical sample handling is performed in… Read more: Navigating the pitfalls in complement analysis
  • NEW Human C3d ELISA
    We are happy to introduce our new ELISA (cat.# HK3017) designed to detect human C3d. What sets this assay apart is its utilization of a distinctive neo-epitope capture antibody that selectively targets a specific C3d region of the alpha chain, which is not available in other C3 variants. This way it specifically distinguishes C3d from native C3… Read more: NEW Human C3d ELISA
