Description
Description: The ISA-3 monoclonal antibody reacts with human ICOS (Inducible COStimulatory molecule), also known as H4, CRP-1 and AILIM. ICOS is a T cell specific activation molecule and a third member of the CD28/CTLA-4 family. Human ICOS has a relative molecular mass of 55-60 kDa, composed of 27 kDa and 29 kDa chains. Human ICOS on activated T cells has potent costimulatory activity for T cell activation and is required for humoral immune responses, in particular for memory B cell and plasma cell generation. ICOS binds to its ligand, B7h/B7RP-1 expressed on activated APCs (antigen presenting cells) and on a number of inflamed peripheral tissues. Plate-bound ISA-3 is costimulatory for T cells and induces production of IL-4, IL-5, IL-10 and other cytokines, but not IL-2. ISA-3 has the same reactivity pattern and characteristics as F44. ISA-3 was generated against the human ICOS antigen. C398.4A, anti-mouse ICOS/H4 (catalog No. 14-9949-82), was shown to cross-react with human ICOS but binds to an epitope different from ISA-3. C398.4A stains activated cells brighter than ISA-3; however, it also exhibits higher staining of non-activated human peripheral blood or isolated PBMC. To achieve the brightest staining of ICOS on activated human T cells, please use 13-9948-82 or 12-9948-42 rather than 11-9948-42. Applications Reported: This ISA-3 antibody has been reported for use in flow cytometric analysis.
ICOS (CD278) encodes a protein that is a member of the CD28 and CTLA-4 cell-surface receptor family. It functions as a homodimer and has a crucial role in cell-cell signaling, immune responses, and the regulation of cell proliferation. ICOS has been linked to various disorders, including Immunodeficiency, Common Variable, 1 and Common Variable Immunodeficiency.
