Chromogenic double staining for CD19 (DAB) and CD3e (RED) visualized T-cell and B-cell populations in the mouse spleen


CD19 (Cluster of Differentiation 19) is a B cell-restricted signal-transduction molecule that plays an important role in the regulation of development, activation, and differentiation of B-lymphocytes. CD19 is considered as a biomarker for B-cells because of its continued expression from very early B cell development stages. It is evident already on pro-B cells and on all later B cell stages, until plasma cell terminal differentiation, when its expression is lost. In complex with CD21, CD81 and CD225, CD19 functions as a dominant signaling receptor on the surface of mature B cells. CD19-deficient mice show defects in initial B-cell activation by T-cell-dependent antigens and in the maturation and/or selection of the activated cells into the memory compartment.
