Human IgD myeloma proteins are shown to have a high carbohydrate content (9-18%) and to exhibit the same heterogeneity in carbohydrate content and composition as myeloma protein of the other immunoglobulin classes. All IgD proteins studied contain N-acetylgalactosamine which is contained in a carbohydrate moiety attached within the "hinge" region of the heavy chain whilst the bulk of the carbohydrate is attached within the Fcdelta region of the molecule.
人IgD骨髓瘤蛋白显示具有高碳水化合物含量(9 - 18%),并且在碳水化合物含量和组成方面表现出与其他免疫球蛋白类别的骨髓瘤蛋白相同的异质性。所有研究的IgD蛋白都含有N - 乙酰半乳糖胺,其存在于连接在重链“铰链”区域内的碳水化合物部分中,而大部分碳水化合物连接在分子的Fcdelta区域内。
