Title:
IgG-BINDING PEPTIDE AND METHOD FOR DETECTING AND PURIFYING IgG USING SAME
Document Type and Number:
WIPO Patent Application WO/2013/027796
Kind Code:
A1
Abstract:
Provided is a peptide capable of binding to human IgG specifically or selectively. A peptide characterized by comprising an amino acid sequence represented by formula (I): (X1-3)-C-(X2)-H-R-G-(Xaa1)-L-V-W-C-(X1-3) (wherein Xs independently represent an arbitrary amino acid residue other than a cysteine residue; C represents a cysteine residue; H represents a histidine residue; R represents an arginine residue; G represents a glycine residue; Xaa1 represents a glutamic acid residue or an asparagine residue; L represents a leucine residue; V represents a valine residue; and W represents a tryptophan residue) and composed of 13-17 amino acid residues, and also characterized by being capable of binding to human IgG.
