Abstract
A process is disclosed for the baseline separation of the &agr; and &bgr; variants of antithrombin III AT-III. The process involves subjecting a sample comprising AT III to cyclodextrin-modified micellar electrokinetic chromatography (CD-MEKC). The CD-MEKC is performed with a buffer comprising boric acid, an anionic tensid, &bgr;-cyclodextrin, and an aliphatic diamine at a basic pH. The CD-MEKC results in the separation of the AT III into AT III &agr; and ATIII &bgr;. The anionic tensid can be sodium dodecyl sulfate and the aliphatic diamine can be 1, 5-diaminopentane.
