Clone REAL453 is an antibody fragment derived from the full Ly-49F 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 REA453 recognizes the mouse Ly-49F antigen (killer cell lectin-like receptor 6), a type II transmembrane natural killer (NK) cell receptor belonging to the Ly-49 family. Members of the Ly-49 family are homodimeric C-type lectin receptors, recognizing MHC class I molecules as ligands and include activating and inhibitory receptor molecules. The inhibitory receptor Ly-49F is expressed on subsets of NK cells, NK-T cells, and on a subpopulation of memory T cells in C57BL/6 mice, but not AKR/J, BALB/c, C3H/HeN, DBA/1, or SJL mice. IL-21 selectively down-regulates Ly-49F on mature NK cells.

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.
