Abstract
125I-labeled TNF(LuKII) (tumor necrosis factor) binds specifically to human and mouse cell lines sensitive to the cytotoxic effect of TNF, but not to cells made resistant to TNF. TNF-sensitive cells have cell surface receptors with a high affinity for TNF(LuKII). Mouse TNF competes with TNF(LuKII) for receptor binding. Scatchard analysis of the binding data yielded linear plots and suggests that TNF(LuKII) binds to homogeneous receptor sites. The number of TNF(LuKII) receptors on two TNF-sensitive cell lines is 200-300 per cell and the affinity constant of the receptor for TNF(LuKII) is approximately 1 X 10(-10) M.Entities:
