Clone REAL339 is an antibody fragment derived from the full CD86 antibody molecule. It displays no binding to Fc receptors. The recombinantly engineered antibody fragments are multimerized to form the REAlease Complex to bind markers with high avidity.
CD86, also known as B7-2 or B70, is an 80 kDa molecule and a member of the immunoglobulin superfamily. Together with CD80 (B7-1) it belongs to the B7 family of co-stimulatory molecules. CD86 is expressed on activated B and T cells, dendritic cells, and monocytes/macrophages. The interaction of CD86 with its ligands CD28 and CD152 (CTLA- 4) plays a critical role in induction and regulation of immune responses, e.g., cross-talk between T and B cells, T cell costimulation, or immunoglobulin class-switching. Binding of CD86 to CD28 on T cells results in transduction of costimulatory signals for activation or proliferation of T cells, or cytokine production.
The REAlease Kits consist of the respective fluorochrome-conjugated REAlease Complexes and the REAlease Support Kit for removal of the REAlease Complexes and optional relabeling with different fluorochrome-conjugated REAlease Complexes.
