<p>The present invention provides a process for isolating and purifying highly anionic target proteins, for example, sulfated proteins. Sulfated proteins have five or more, sulfations. In a preferred embodiment, the sulfated protein has six sulfations, e.g., six sulfations on N-terminal tyrosine residues, as embodied in PSGL-1 (P-selectin glycoprotein ligand).</p> |
