Hello, I am trying to come up with a good staining combination for flow cytometry of plasma cells from both bone marrow and PBMCS, and I was wondering what kind of a CD19 expression pattern I can expect to see in plasma cells in these two compartments? I know that terminally differentiated cells do not express CD19, but when exactly do they lose this marker, and where? Thanks.
