Abstract

Phosphorylated peptides are extracted from digests of biological liquids and other peptide mixtures by fractionation on ceramic hydroxyapatite. The ceramic hydroxyapatite is readily usable in a centrifuge, allowing for rapid fractionations of a large number of small volume samples, and accordingly high throughput.
