Evaluation of binding ability. (a) Flow cytometry assessment of SSFH/Cas9 for CD123 binding specificities. FAM-labeled DNA sequences were incubated with CD123-positive cells Molm-13 and CD123-negative cells RCH-ACV. Fluorescence signal was assessed. (b) Competing assay. Molm-13 cells were incubated with FAM-labeled CD123 antibody and increasing concentrations of free SS30 or SSFH/Cas9. Cells were centrifuged, supernatant fluid were collected and analyzed by fluorometer. The mean fluorescence intensities (MFI) of FAM were analyzed. (c) Confocal microscope assessment of SSFH/Cas9 for CD123 binding specificities.
