Miltenyi, 130-102-030, CD275 (B7-H2) Antibody, anti-mouse, Biotin

Overview
Clone HK5.3 recognises murine CD275, which is also known as B7-H2 and ICOSL. CD275 is a type I membrane protein and belongs to the Ig superfamily, B7 family of costimulatory molecules. Expression of CD275 is found on antigen presenting cells such as B cells, dendritic cells, and monocytes. CD275 costimulates T cells upon binding to ICOS, which is expressed on activated T cells. In mouse, CD275 binds only ICOS, whereas in humans it can interact with other T cell costimulatory molecules, CD28 and CTLA-4. To appropriately regulate the activation of immune response, the ICOS-CD275 interaction can also lead to downregulation of CD275 expression which allows prevention of hyperreaction of T cells.
