title: The allergenic structure of allergen M from cod. I. Tryptic peptides of fragment TM 1.
abstract: In attempts to locate the allergenic active sites of fragment TM 1 of allergen M from cod, the allergenicity of the tryptic hydrolysis peptides was examined both in vivo and in vitro. A duodecapeptide (residues No. 33-44) was tentatively suggested to incorporate at least one allergenic determinant. All the tryptic peptides were less active than allergen M as shown by the in vivo titration experiments. The activity of the peptides was not due to contamination of intact allergens.
