Comparison of different methods for LDL isolation and radioiodination on liver LDL receptor binding in vitro.


Lipoproteins were isolated either by immunoaffinity chromatography (LDL and VLDL) or ultracentrifugation (LDL). Purified lipoproteins were labeled with 123I using either Iodogen or iodine-monochloride (IC1) each followed by purification with gel-chromatography or dialysis (total of 4 combinations). Lipoprotein-concentrations of 0.1-6 micrograms protein/mL… (More)
