Preparation and rapid resolution of Xenopus phosvitins and phosvettes by high-performance liquid chromatography.

The presence of acidic phosivitins phosvettes in Xenopus laevis yolk platelets and their purification by (NH4)2SO4 precipitation of associated lipovitellin were documented by polyacrylamide gel electrophoresis followed by staining with Stains-all. Procedures were further developed to resolve the various entities present in the crude phosvitin/phosvette fraction by size-exclusion, anion-exchange, and hydrophobic interaction chromatography, using a Pharmacia FPLC system, and their resolution was documented by both electrophoresis and two-dimensional chromatography. Four major entities (phosvitins 1 and 2; phosvettes 1 and 2) were observed, but microheterogeneity was also apparent, particularly by hydrophobic interaction chromatography. The new separation procedures require min/h rather than h days.
