CD66b / APC / REA306

Product Details

Description	Clone REA306 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 interleukin 5 (IL-5). Crosslinking of CD66b on peripheral blood neutrophils mediates the release of IL-8 from intracellular storage. \| Additional information: Clone REA306 displays negligible binding to Fc receptors. \|

About CD66b
Enables protein heterodimerization activity. Involved in heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules. Located in cell surface and extracellular space. Biomarker of severe acute respiratory syndrome. [provided by Alliance of Genome Resources, Apr 2022]

About APC
Allophycocyanin (APC) is a fluorescent protein derived from cyanobacteria and red algae and a potent donor fluorophore to create tandem dyes that can be excited off the 633-640 nm laser. APC has an excitation peak at 650 nm and a emission peak at 660 nm.
