title: Simple one-step procedure for the separation of apolipoproteins A1 and A2 by high-performance liquid chromatography.
abstract: A simple assay method for apolipoproteins apo A1 and apo A2 by HPLC is introduced. The simple one-step method is based on fractionation of apo A1 and apo A2 from other serum proteins which are precipitated at 100 degrees C and removed by centrifugation. The apo A1 and apo A2 which remain in solution can be recovered and resolved by size-exclusion chromatography without ultracentrifugation and delipidation by an organic solvent. This makes sample preparation easier. The recoveries of apo A1 and apo A2 were 104.26% and 101.04%; the precision (C.V.%) of apo A1 and apo A2 was 0.88 and 1.63 respectively.
