CD66b Antibody, anti-human, PE

Detection of CD66b+ cellsClone REAL926 is an antibody fragment derived from the full CD66b 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 REAL926 recognizes the human CD66b antigen, a glycosylphosphatidylinositol (GPI) linked protein which is also known as Carcinoembryonic antigen-related cell adhesion molecule 8 (CEACAM8). CD66b is exclusively expressed on neutrophils and eosinophils and on leukocytes of chronic myeloid Leukemia patients and bone marrow. Under normal conditions, neutrophils have minimal expression of CD66b, but incubation in vitro with inflammatory agonists rapidly increases this expression. Furthermore, expression of CD66b in eosinophils is enhanced in vivo in patients with a helminth infection, specifically with Schistosoma mansoni. The eosinophil expression of CD66b is also enhanced in vitro by incubation with activated lymphocytes or by brief incubation with IL-5. Crosslinking of CD66b on peripheral blood neutrophils mediates the release of IL-8 from intracellular storage. | For removal of REAdye_lease fluorochromes for optional relabeling with different fluorochrome-conjugated REAdye_lease antibodies use the REAlease Support Kit (130-120-675). |
