The monoclonal antibody 755 recognizes an epitope located in the C-terminal 360 amino acids-on the alpha chain of C3, thereby recognizing C3b and full C3. The complement system is an important factor in innate immunity. The third complement component, C3, is central to the classical, alternative and lectin pathways of complement activation. The synthesis of C3 is tissue-specific and is modulated in response to a variety of stimulatory agents. C3 is the most abundant protein of the complement system with serum protein levels of about 1.3 mg/ml. An inherited deficiency of C3 predisposes a person to frequent bacterial infections. C3 fragments are deposited in tissues at sites of antibody-mediated immunopathology. In ulcerative colitis and idiopathic chronic inflammatory bowel disease, the deposition of C3 in the diseased mucosa has been reported. After activation of the complement system, certain enzymes become active, resulting in the cleavage of C3 into C3b and the anaphylatoxin C3a. C3b becomes attached to immune complexes and is further cleaved into iC3b, C3c, C3dg and C3f. Within the alternative pathway of complement, C3b plays a critical role in the amplification loop initiated by spontaneous hydrolysis of C3.

  • 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
