Purification and characterization of bovine lipoproteins: resolution of high density and low density lipoproteins using heparin-Sepharose chromatography.

abstract：:We previously have shown that LDL-R354, a truncated low density lipoprotein (LDL) receptor, is a calcium binding protein. LDL-R354 is composed of the ligand binding domain and repeat A of the EGF precursor homology domain of the full-length human LDL receptor. We also found that Ca2+ was required for the interaction b...
