Flow cytometry Anti-bodies Human - CD123/IL3-R

Flow cytometry is an immunophenotyping technique whereby sing cell suspensions are stained for either cell surface markers or intracellular proteins by fluorescently-labelled antibodies and analyzed with a flow cytometer, where fluorescently-labelled molecules are excited by the laser to emit light at varying wavelengths, which is then detected by the instrument. There are several key criteria which are required to be kept in mind while designing a flow experiment- 1. Antibody titration (optimal dilution of antibodies should be calculated in order to avoid over- or under- saturated signals for proper detection of surface and intracellular markers), 2. Precision (3 or more replicates of the sample should be used per experiment), 3. Specificity (proper isotype controls should be included in the experiment), 4. Day-to-day variability (experiments should be repeated 3 or more times to ensure consistency and avoid variability due to flow cytometer settings), 5. Antibody interaction (Fluorescence minus one or FMO should be used, which is the comparison of signals from panel minus one antibody vs. the full panel), and 6. Antibody stability (fluorescently-labelled antibodies should be stored at 4C).

PE-Cy™7 Mouse Anti-Human CD123

BD Biosciences

Upstream tips	Protocol tips	Downstream tips
To perform flow cytometry analysis and to sort BFU-E and CFU-E cells from primary human samples including BM, cord blood, and peripheral blood, we isolated CD45+ cells from mononuclear cells (MNC) derived by Ficoll density gradient separation, followed by positive selection using CD45 magnetic beads.	Ab incubation for 30 minutes in the dark. Cells were washed twice with 40 mL phosphate-buffered saline/0.5% bovine serum albumin, resuspended in 5 mL phosphate-buffered saline/0.5% bovine serum albumin, and stained with the viability marker 7-AAD on ice for 10 minutes in the dark.	The analysis was performed using BD FACSDiva. Sorting was performed using a MoFlo high-speed cell sorter (Beckman Coulter).

	Heparinized bone marrow (BM) and peripheral blood (PB) cells (106 leukocytes per tube) were incubated with various combinations of mAb (Supplementary Table S3) for 15 minutes. Then, erythrocytes were lysed in FACS-Lysing-Solution (BD Biosciences, San José, CA, USA). Washed cells were acquired on a FACSCalibur (BD Biosciences) and analyzed by FlowJo software (TreeStar, Ashland, OR, USA)

	Cells were stained with a fixable Live/Dead dye (ThermoFisher Scientific) concurrently with saturating concentrations of surface mAbs (Table S2) in a buffer containing 50%ABrilliant Violet Buffer (BD Bioscience) and 50%APBS for 30min at 4°C.	All samples were acquired in a 0.1% saponin buffer on an X20FortessaASORP (BD Biosciences) and analysed in FlowJo (TreeStar).
