![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=1724250157&Signature=vh0--txAdLNAxJf52QLEB60Oy9y1dVpjmgLHbLqSmQ7Rxsw93aJ5TsdPAEWEr7BtqG5huodgTAl4Fe3sdDeG0iU4c0ZdUI19Yb33xLtwLz088aND9xBqL0K0ImBiAFFma6Rl3CwGrXcv1p4DksemSwEMjRwbPFRI-6zYZ9xWf8VlpuYZbRqQ2XUg9oE3xv9JyuVvf8jttR3FW5hWLy7VXhGQiXIi7WkZ1l6ZAmmBLOuleZkwm~FUiqonXN6JpsLzGoPQ62TvpUeSRgzE3o3-0cXuURk3LSmD-X~Fyg0m~NJilBdUsPaJZDkxGNVbTWFDVUwduha57ZXKPCrkZjmIWw__&Key-Pair-Id=APKAIE5G5CRDK6RD3PGA)
