CD56 antibodies, human

CD56 antibodies, human

Clone: REA196 | Dilution: 1:11
Clone REA196 recognizes the human CD56 antigen, a glycoprotein of the Ig-superfamily, also known as neural cell adhesion molecule (NCAM), which is expressed in blood on practically all resting and activated NK cells and on a minor subset of CD3
T cells. CD56 is also expressed in brain (cerebellum and cortex) and at neuromuscular junctions. Certain large granular lymphocyte (LGL) leukemias, small-cell lung carcinomas, neuronal-derived tumors, myelomas, and myeloid leukemias also express CD56.
Additional information: Clone REA196 displays negligible binding to Fc receptors.

REAfinity clone is tested against different known clones, in a blocking experiment, to identify whether they recognize completely overlapping (++), partially overlapping (+), or completely different epitopes (-). In a blocking experiment, cells are incubated with an excess of purified unconjugated REAfinity clone followed by staining with conjugated form of the other known clones.
