. After incubation with monoclonal antibodies for 15 min (min) at 4°C, erythrocytes were lysed with ammonium chloride (PharmLyse, BD Biosciences, San Diego, California) at room temperature for 10 min using a standard lyse/wash technique. Samples were acquired on FACSCanto II instruments (BD Biosciences). For the detection of cytoplasmic antigens, cells were fixed and permeabilized using 4% formaldehyde and 0.25% Saponin. CD30‐PE was purchased from Beckman Coulter and all other antibodies were purchased from BD Biosciences. |
). A total of 200,000 events were acquired for assessment of these investigated antibodies.
Data were analyzed using FCS Express software (De Novo Software, Los Angeles, California). Non‐viable cells, debris, and aggregates were excluded based on forward scatter‐height/forward scatter‐area (FSC‐H/FSC‐A). |

| 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 or appropriate isotype controls (all from BD Biosciences) incubated 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). The number of BFU-E or CFU-E cells in one million MNCs was quantitated. |

cells were transferred, centrifugation at 1500 g for 10 min and incubated with antibodies for 20 min at 37 °C. Annexin V was then added and stained for 15 min at room temperature. After incubation, BMMCs were washed, centrifuged, measured by a FACSCanto II (BD Biosciences) and resulting data were analysed using FlowJo software. |
