摘要: The association of 125I-labelled rat high density lipoproteins (125I-HDL) to suspended hepatocytes was studied at 4°C. 125I-HDL associated isolated by two processes—one and one low affinity. cell-association 1251-HDL exhibited saturation kinetics inhibited varying degrees with both human such as VLDL, LDL HDL but not lipoprotein deficient serum or asialo-fetuin. did require divalent cations could be reduced pronase treatment the cells. binding site clearly different from receptor for in extrahepatic cells since heparin apolipoprotein E compete binding.
