cFluor® B532 Anti-Human CD19 (HIB19)
The HIB19 monoclonal antibody binds to human CD19, a 95-kDa type I transmembrane glycoprotein in the immunoglobulin superfamily. CD19 forms a signal transduction complex with the complement receptor 2 (CD21), a tetraspanin membrane protein, TAPA-1 (CD81), and Lue 13 to function as a dominant signaling component on the surface of B cells1,2. It is expressed in all phases of B cell development, maturation and differentiation except at the terminal stage of differentiation, lost in plasma cells3. It is also present on follicular dendritic cells and absent on T cells.
The antibody was conjugated to a fluorophore and puriﬁed by afﬁnity chromatography.

Each lot of this antibody is quality control tested using flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µL per 1 million cells in a staining volume of 100 µL. If whole blood is analyzed, then use 5 µL per 100 µL. It is recommended that users titrate the antibody to obtain the optimal result for their specific application.
