Extra Details:: The CD19 antigen (95kD) is expressed from the earliest stage of B progenitor development, on all peripheral B cells including germinal centre B cells, and all B cell lines and B cell leukaemia tested. T cell and monocytic cell lines are negative and the antigen is lost on B cell maturation to plasma cells. The antigen is a type I integral membrane glycoprotein whose in vitro inhibition will influence B cell activation and proliferation. Applications: Immunofluorescence: 1:200-1:1000. Flow cytometry: 1:200-1:400. ELISA: Suggested dilution 1:10000. Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only.
