Read moreThe anti MASP-1 monoclonal antibody clone 3/3 recognize the unique MASP-1 serine protease (SP) domain. Mannan-binding lectin serine protease 1 or mannose-associated serine protease 1 (MASP-1) is an enzyme that is encoded by the MASP1 gene. Three types of human MASP have been reported, MASP-1, MASP-2 and MASP-3. MASP-1 is a serine protease that functions as a component of the lectin pathway of the complement system. The lectin pathway can be activated by the pathogen recognition receptors (PRRs) collectins (such as MBL and collectin kidney 1 (CL-K1 or CL-11) or by ficolins (ficolin-1 or M-ficolin, ficolin-2 or L-ficolin, and ficolin-3 or H-ficolin). The PRRs recognize carbohydrate and acetylated residues on the surface of pathogens and altered cells. After binding, MASP-1 zymogen auto activates and trans activates MASP-2. MASP-2 further cleaves the C4 complement component, whereas both MASP-1 and MASP-2 cleave C2. This leads to the formation of the C3 convertase (C4bC2b). The C3 convertase cleaves C3 leading to complement terminal pathway activation and thus mediating the destruction of infectious agents.
- IA: HM2408 can be used as capture antibody.
- FS: C3 deposition was not inhibited with antibody HM2408 in an experiment with lectin pathway activation with c3 deposition measurement.

- Navigating the pitfalls in complement analysisOur 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 ELISAWe 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
