The mouse monoclonal antibody 7C9 recognizes an extracellular epitope of SIGLEC8, an eosinophil marker, expressed e.g. in lymph nodes and spleen.
Purification
Purified antibody is conjugated with R-phycoerythrin (PE) under optimum conditions. Unconjugated antibody and free fluorochrome are removed by size-exclusion chromatography.
Immunogen
Extracellular domain of human SIGLEC8 fused with Fc fragment of human IgG1
Flow cytometry: The reagent is designed for analysis of human blood cells using 10 μL reagent / 100 μL of whole blood or 106 cells in a suspension. The content of a vial (1 ml) is sufficient for 100 tests.
Sialic acid binding Ig like lectin 8,SIGLEC8 is a sialic acid binding lectin similar to CD33. In its cytoplasmic comain it contains an immunoreceptor tyrosine-based inhibitory motif (ITIM), and a motive similar to a binding site for SLAM-associated protein. SIGLEC8 is expressed e.g. in lymph nodes and spleen. It is an eosinophil marker, although it can be found also on the surface of mast cells. Crosslinking of SIGLEC8 leads to apoptosis. Soluble form of SIGLEC8 can be foud in human serum, especially in case of eosinophil-associated diseases.,SAF2
