Specifications for CD40 Antibody, anti-human, REAdye_lease™


Clone REAL659 is an antibody fragment derived from the full CD40 antibody molecule. It displays no binding to Fc receptors. The recombinantly engineered antibody fragments are multimerized to form the REAdye_lease Complex to bind markers with high avidity.
Clone REAL659 recognizes the human CD40 antigen, a transmembrane receptor of the tumor necrosis factor gene superfamily. CD40 is a co-stimulatory protein constitutively expressed by antigen presenting cells, including dendritic cells, B cells, and macrophages and on endothelial, smooth muscle cells, and fibroblasts. The binding of CD40 to CD154 (CD40L) on T helper cells activates antigen presenting cells and enhances the expression of cytokines, chemokines, matrix metalloproteinases, growth factors, and adhesion molecules. CD40 has been shown to interact with members of the TRAF family.
For removal of REAdye_lease fluorochromes for optional relabeling with different fluorochrome-conjugated REAdye_lease antibodies use the REAlease Support Kit (130-120-675).
