Overlay histogram showing K562 cells stained with EPOR (green line). The cells were fixed with 2% paraformaldehyde (10 min) and then permeabilized with 90% methanol for 10min. The cells were then icubated in 2% bovine serum albumin to block non-specific protein-protein interactions followed by the antibody (EPOR, 1:25 dilution) for 60min at 37ºC. The secondary antibody used was Goat-Anti-Rabbit IgG, DyLight 488 Conjugated Highly Cross-Adsorbed (OH191631) at 1/200 dilution for 40min at 37ºC. Isotype control antibody (blue line) was rabbit IgG1 (1ug/1x10^6 cells) used under the same conditions. Acquisition of >10, 000 events was performed.
