Monoclonal antibody M81 reacts with an epitope on human C protein activated C1s, a subcomponent of the first component of C (C1). Activated C1s is a glycosylated single-polypeptide zymogen, MW 85 kD. Activation of the proenzyme C1s occurs through cleavage by the active form of C1r. The activated protease, activated C1s, consists of a disulfide-linked H chain and a L chain. Activated C1s is a serine protease and its catalytic site is located in the L chain. Activation of the classical C pathway is triggered by activated C1s which cleaves C4 and C2 to form the C3 convertase, C4bC2a. The epitope recognised by the antibody M81 is domain IV and/or V of the gamma-domain of activated C1s. Monoclonal antibody M81 blocks C4 activation and C4 binding to activated C1s. The antibody reacts around the binding site of C1s and reacts with both active and inactive C1s.

Application
Flow cytometry, Frozen sections, Functional studies, Immuno assays, Immuno precipitation, Paraffin sections, Western blot

Use
For immunohistology, flow cytometry and Western blotting 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 1:10. For inhibition of C4 activation by C1s dilutions have to be made according to the amounts C1s to be inactivated.

  • 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
