NoC1 binding to TSG-6. ¹²⁵I-NoC1 binding to different amount of TSG-6Q (A) or Link_TSG6 (B) coated onto wells of a microtiter plate was tested by the solid phase assay. The assays were performed at 37°C in the presence of Ca²⁺, Mg²⁺ (solid lines) or in the presence of 5 mM EDTA, (dotted lines). Background values are subtracted from each data point (593 ±43). Results (mean cpm ± S.E.M.) shown are representative of two independent experiments performed in triplicate.
