Clone REAL463 is an antibody fragment derived from the full Integrin β5 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.

Clone REAL463 recognizes the human integrin β5 antigen, a 95 kDa glycoprotein single-pass type I membrane protein. Integrins are a family of transmembrane receptors that mediate adhesion of cells to extracellular matrices, as well as intercellular interactions. These interactions transduce signals that control complex cell functions such as proliferation, differentiation, and survival, and require the regulation of gene expression. Integrins are heterodimeric glycoprotein receptors and exist as non-covalently bound α and β subunits. The integrin αV/β5 heterodimer is found on many types of tissue cells, such as epithelial cells, endothelial cells, keratinocytes, and osteoblastic cells. It is a receptor for fibronectin and vitronectin and acts as a receptor for adenovirus type C.

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.
