Enhanced and conventional indirect immunofluorescence analysis of cell surface SLC expression by B lineage cells.

(A) CD19⁺ cells in human bone marrow and (B) B220⁺ cells in mouse bone marrow were examined with digoxigenin-labeled anti-VpreB and anti-λ5 mAbs and antidigoxigenin-coated fluorochrome-loaded liposomes as a second-step reagent or with biotinylated anti-VpreB mAb and streptavidin-PE.
