Anti-human B Cell antibodies for use in flow cytometry. These single-color reagents are of value to the study of functionally mature B cells and related lymphoproliferative disorders.This antibody targets the 105 kDa FMC7 antigen, which is present on a subpopulation of functionally mature B cells. It is present in similar quantities in normal (resting) B cells and in rapidly dividing cell lines. FMC7 antigen may be a conformational epitope of CD20. Anti-B Cell, FMC7, reacts with a subset of B cells that also expresses surface membrane immunoglobulin (SmIg). The antibody does not stain B cells without SmIg, T cells and monocytes.Further information and references to relevant literature are available in the product’s Instructions For Use.
