Anti-Mouse TER-119 (Erythroid Cells) - FITC (T652-GRP)

TER-119 recognizes a 52 kDa cell surface protein that strongly associates with glycophorin A on the erythrocyte membrane 1 . The antigen is not present on a number of tested cell lines, including T cell, B cell, macrophage, mast cell, fibroblast, epithelial, and murine erythroleukemia cultured lines. TER-119 is a mouse erythroid lineage-specific rat monoclonal antibody that reacts with 100% of mature erythrocytes and 80-90% of day 14 fetal liver cells, after which the percentage of TER-119+ fetal cells declines to 40-50% 2. Additionally, TER-119 stains 20-25% of adult mouse bone marrow cells and 2-3% of spleen cells, but not thymocytes or lymph node cells. TER-119 was produced in Wister rats immunized with BALB/c fetal liver cells 1 . Spleen cells were fused with X63.Ag8.653 myeloma cells to produce a hybridoma clone reactive against fetal liver cells. TER-119 recognizes a 7,9 di-O-acetyl sialic acid glyco-epitope 3 . Additionally, the epitope is sensitive to hemagglutinin esterase derived from bovine coronavirus (Mebus strain) but not influenza C.
