The immunochemical relationship between CEA, NCA and NCA 2 was studied in guinea-pigs. Strong cross reactions were found between these antigens, either in delayed or anaphylactic reactions. Some specific determinants for each antigen could still be demonstrated. Delayed hypersensitivity is likely to be due to the protein moiety of the molecules while anaphylactic reactivity could probably be related to their glucidic parts. Consequently, CEA and NCA have common antigenic determinants on their glucidic and peptidic moieties, perhaps more on the latter ones.
在豚鼠中研究了癌胚抗原(CEA)、非癌胚抗原(NCA)和NCA 2之间的免疫化学关系。在迟发型或过敏反应中,这些抗原之间均发现强烈的交叉反应。每种抗原的一些特异性决定簇仍可被证实。迟发型超敏反应可能归因于分子的蛋白质部分,而过敏反应性可能与其糖部分有关。因此,CEA和NCA在其糖部分和肽部分具有共同的抗原决定簇,可能在后者上更多。
