Heterogeneity of rat plasma albumin and drug binding.
Rat plasma albumin fractionated by Sephadex G-75 (superfine) gel filtration from freshly prepared rat plasma was further separated into three major fractions by chromatofocusing column chromatography. All the fractionated albumins had high binding affinity for the fluorescent probe 8-anilino-1-naphthalenesulfonic acid, as the model compound for acidic drugs, and were found to be immunologically identical.
