Apolipoprotein H: a two-step isolation method

A new method for the purification of apolipoprotein H by affinity
chromatography followed by continuous-elution electrophoresis is described.
It is both simpler and less complicated than the chromatographic and
electrophoretic methods usually used. In addition, apolipoprotein H is
isolated in a pure, structurally uncleaved form. This is of importance, as
impairment has been detected in commercial preparations. The separation and
purification of apolipoprotein H is a necessary prelude to its quantitative
determination and phenotyping, and hence the clarification of its
physiopathological mechanisms in lipid metabolism.
