Protective and nonprotective epitopes of chemically synthesized peptides of the NH2-terminal region of type 6 streptococcal M protein.

The paper refers to amino acid positions of the mature protein as opposed to the precursor. One of three antisera to this peptide was minimally reactive to a purified M protein pepsin fragment from heterotypic serotype 24.

本文所提及的氨基酸位点均针对成熟蛋白，而非其前体蛋白。针对该肽段的三份抗血清中，有一份与取自异型血清型24的纯化M蛋白胃蛋白酶片段仅表现出极弱的反应性。
