32D cells transfected with either the full-length or truncated EpoR demonstrate equivalent growth at high Epo concentrations. Cells were grown in 2 U/mL Epo for 3 days and then assayed in triplicate for 3H-thymidine incorporation. 32D/neo cells do not proliferate in Epo because they lack Epo receptors. Standard error bars are indicated.
