There is disclosed a peptide possessing an ability to bind to the human antibody to the nicotinic acetylcholine receptor and represented by the formula:
wherein A stands for a peptide residue, one of X and Y stands for a single bond, an amino acid residue selected from the class consisting of Asp, Glu, Lys and a divalent group represented by the formula,
(wherein n stands for an integer in the range of 1 to 17), or a peptide residue formed by peptide linkage of two to ten amino acid residues of at least one species selected from the class mentioned above and the other of X and Y stands for an amino acid residue selected from the class consisting of Asp, Glu, Lys and a divalent group represented by the formula,
(wherein n stands for an integer in the range of 1 to 17), or a peptide residue formed by peptide linkage of two to ten amino acid residues of at least one species selected from the class mentioned above, and Z stands for a hydroxyl group or an amino group and an adsorbent having immobilized on a carrier the peptide mentioned above. A method for the production of the adsorbent and a method for the use of the adsorbent are also disclosed.
