METHOD FOR PRODUCING A PURIFIED IMMUNOLOGICALLY ACTIVE TRYPTIC PEPTIDE AND TRYPTIC PEPTIDES PREPARED THEREBY

摘要

A tryptic peptide is produced by partial tryptic digestion of purified, high molecular size colon-specific antigen-p (CSAp), to produce a lower molecular size antigen carrying the CSAp antigenic determinant. The tryptic peptide is used to produce monospecific anti-CSAp antibodies.
