The MEM-78 monoclonal antibody specifically recognizes CD10. CD10 is a 100 kDa type II transmembrane, glycosylated, zinc-containing metalloprotease. The CD10 antigen is also known as common acute lymphoblastic leukemia antigen (CALLA), neutral endopeptidase (NEP), gp100, and enkephalinase. The CD10 antigen is found on lymphocytes from samples with acute B-lymphoid leukemia. The CD10 antigen is also present on a wide variety of normal and neoplastic cell types including renal epithelia, fibroblasts, granulocytes, germinal center B lymphocytes, neutrophils, some T-cell leukemias, and some lymphoma, melanoma, and glioma cell lines. The CD10 antigen cleaves a number of biologically active peptides, including fMLP, and may modulate the chemotactic activity of fMLP towards neutrophils. Inhibition of the CD10 antigen promotes B-cell maturation, suggesting that it plays a role in B-cell development.
The antibody was conjugated to BD Horizon™ BB700, which is part of the BD Horizon Brilliant™ Blue family of dyes. It is a polymer-based tandem dye developed exclusively by BD Biosciences. With an excitation max of 485 nm and an emission max of 693 nm, BD Horizon BB700 can be excited by the 488 nm laser and detected in a standard PerCP-Cy™5.5 set (eg, 695/40-nm filter). This dye provides a much brighter alternative to PerCP-Cy5.5 with less cross laser excitation off the 405 nm and 355 nm lasers.
