![Figure 4. Specific cell-surface binding of [125I]-rHuEpo was detected in 1 of 5 of the higher EpoR protein–producing cell lines. Specific binding of [125I]-rHuEpo to live intact cells (1 × 106 cells) is expressed as percentage of control UT-7/Epo cells and is the average of 2 to 3 experiments (N = 5 samples/cell for each experiment). The negative control was 769-P cells. Error bars represent SD. Note specific binding with NCI-H661 cells (P ≤ .001).](https://ash.silverchair-cdn.com/ash/content_public/journal/blood/115/21/10.1182_blood-2009-10-248674/5/zh89991050730004.jpeg?Expires=1735512743&Signature=xHdIQa8EVA9UrBPpqwwO35u776dPscM0PF6au-TkS4DrMALTL8hMiHPa3H5qMb-LRtUvi1W7B81pSn3Y-~KFN5-K4LiYwCY-v~Ga3k3edkOUpkmAb9MZpItKdIYTl8R-lOEOUawqhDVOODsbjazEMJF3cvHqYhnTuU1tGcFSbaAMi2MkXG2O90Vzr6GKcWMK-BGExVDiydx1CPel2ghJ~nlBu1Wn9zOoN4UaKZw59LaonmDS9yNLTZ4-89VW4Q2r5uCDrjc0EOiUJgWozh~VjSJzxZuI9qWzXNmezwmi8XQ6mBoUgtTw3mQQCZnAauHYTU8vYbrlepNTDdxc5~b00w__&Key-Pair-Id=APKAIE5G5CRDK6RD3PGA)
