First, prealbumin was isolated from several milliliters of plasma by a two-step procedure: affinity chromatog- raphy on a Blue Cellulofine (Seikagakukogyo) column and ion exchange chromatography on a Mono Q column (Pharmacia Fine Chemicals). Then separation of the prealbumin variant from normal ...
A Zorbax® SB-C18 high-performance liquid chromatography (HPLC) column (5 μm; 4.6 × 150 mm) for FLA analysis was purchased from Agilent Technologies (USA). HPLC-grade solvents methanol and acetonitrile were purchased from Sigma-Aldrich and Fisher Scientific (USA). All other solvents...
