Figure 2.
Cell yield and fraction analyses for MACS optimization trials of varying antibody and microbead concentrations. MACS cell yields of retained and flow-through fractions for pure ALPL+ optimization sorts when (a) microbead dilution was varied with a fixed (1:11) antibody dilution and (b) antibody dilution was varied with a fixed (1:5) microbead dilution. (c) Distributions of ALPL+ cells within retained and flow-through fractions of antibody-varied trials displayed in (b) were assessed via flow cytometry and confirmed a high false-negative rate in flow-through fractions. (APC fluorescence corresponds to APC dye on anti-ALPL antibody).
