Some tandem dyes including PE/Dazzle™ 594, APC/Fire™ 750, PE/Cy7, PE/Cy5, PerCP/Cy5.5 and especially APC/Cy7, can be bound non-specifically by monocytes and macrophages. In flow cytometry assays, this can create confounding results that are difficult to interpret. To counter this, BioLegend has formulated a new and effective blocking reagent, True-Stain Monocyte Blocker™. This non-antibody based blocking solution reduces non-specific monocyte binding to fluorophores without affecting desired staining of monocytes. Now you can immuno-label monocytes with confidence, fully trusting your true staining results. |
PBMCs were stained with 5 μl/test of antibody in 100 μl of cells at 1x106 cells/ml. Fig. A-C are CD3 APC/Cy7 co-stained with CD14 BV421™ with no blocking solution (A), TruStain FcX™ blocker alone (B) or the True-Stain Monoctye Blocker™ alone (C). Fig 1D-F are CD56 PE/Cy5 co-stained with CD14 BV421™ with no blocking solution (D), TruStain FcX™ blocker alone (E) or the True-Stain Monoctye Blocker™ alone (F). Fig. 1G-I are CD19 PE/Dazzle™ 594 co-stained with CD14 BV421™ with no blocking solution (G), TruStain FcX™ blocker alone (H) or the True-Stain Monoctye Blocker™ alone (I). |
