Abstract
The present invention provides a tag peptide comprising an amino acid sequence represented by the following formula (I): X1-Tyr-X2-Gly-Gln-X3 (I) (wherein X1, X2 and X3 are the same or different and each represent any amino acid residue) and an antibody against the tag peptide. By combined use of the tag peptide and antibody of the present invention, a system that enables proteins expressed from cloned genes to be highly purified in an inexpensive and easy manner can be established.
