TTR interacts with IGF-IR. Binding of ¹²⁵I-TTR to sIGF-IR immobilized in microtiter wells (5 μg/well). a ¹²⁵I-TTR was added to each well in the presence or absence of the indicated molar excess of cold TTR. b Binding of ¹²⁵I-sIGF-IR to TTR immobilized in microtiter wells (5 μg/well) in the presence or absence of the indicated molar excess of TTR, cold sIGF-IR , anti-TTR IgG (α-TTR), anti-IGF-IR IgG (α-IGF-IR), or non-immune IgG (NI IgG)
