Abstract
Peptide ligands which bind to von Willebrand Factor (vWF) are disclosed. These peptides are selected from the group consisting of RLHSFY, RLKSFY, RLNSFY, RLQSFY, RFRSFY, RIRSFY, RVRSFY, RYRSFY, RLRSFY, HLRSFY, and KLRSFY. The preferred peptide ligand has the sequence RVRSFY. A method of using the disclosed peptides to purify vWF comprises binding the peptides to a support, then passing a solution containing vWF over the supports under condition such that the vWF will selectively bind to the peptides, and then eluting the vWF.
Claims2
A composition comprising a defined sequence of six consecutive amino acid residues, wherein the defined sequence is selected from the group consisting of RLHSFY, RLKSFY, RLNSFY, RLQSFY, RFRSFY, RIRSFY, RVRSFY, RYRSFY, RLRSFY, HLRSFY, and KLRSFY.
A method of purifying von Willebrand factor comprising contacting a solution containing von Willebrand factor with a substrate comprising an amino acid sequence selected from the group consisting of RLHSFY, RLKSFY, RLNSFY, RLQSFY, RFRSFY, RIRSFY, RVRSFY, RYRSFY, RLRSFY, HLRSFY, and KLRSFY under conditions sufficient to bind von Willebrand factor to the substrate .
