Mouse monoclonal antibody raised against native CD19.
Native purified CD19 from SKLY 18 lymphoma cells.
CD19 antigen is a single chain, type I integral membrane glycoprotein with a molecular weight of 95KDa. Clone J4.119 cross-reacts with B cells from Macaca fascicularis, Macaca mulatta and Papio cynocephalus . It reacts weakly with B cells from Rhesus monkey. The clone J4.119 was assigned to the CD19 cluster for differentiation at the 4th International Workshop on human Leucocyte Differentiation Antigens (HDLA) in Vienna, Austria (1989).
Flow Cytometry (2ug per 5x105 cells/test or 100ul blood sample) The optimal working dilution should be determined by the end user.
