The FITC conjugated monoclonal antibody BV16 recognizes the human junction adhesion molecule (JAM)-A. Together with JAM-C (JAM-2) and JAM-B (VE-JAM or JAM-3), JAM-A belongs to a family of adhesion proteins with a V-C2 immunoglobulin domain organization and their molecular weight is about 30-40 kDa. JAMs are important for a variety of cellular processes, including tight junction assembly, leukocyte transmigration, platelet activation, angiogenesis and virus binding. JAM-A is expressed by endothelial and epithelial cells, platelets, neutrophils, monocytes, lymphocytes and erythrocytes. Like all other JAMs, JAM-A plays an important role in tight junctions where it is involved in cell-to-cell adhesion through homophilic interaction. It codistributes with other tight junction components as ZO-1, 7H6 antigen, cingulin and occludin. JAM-A also plays an important role in leukocyte transmigration. Leukocyte transmigration can be blocked by antibodies and by soluble JAM-A/Fc fusion proteins. Homophilic JAM-A interactions between leukocytes and the endothelium but also heterophilic interactions of JAM-A with the beta 2-integrin leukocyte function-associated antigen-1 (LFA-1) are considered to actively guide leukocytes during transmigration. Several studies imply a role for JAM-A in the initiation of atherosclerosis, since JAM-A is upregulated on early atherosclerotic endothelium. Adhesion of the activated platelets on activated endothelium is mediated by homophilic interactions of JAM-A.

    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
