Two monoclonal antibodies, HD 66 and CRIS-4, by which the new CD 76 B-cell-associated cluster was defined, bound to several gangliosides (sialic acid containing glycolipids) of different polarity. One of the gangliosides recognized by HD 66 could be identified as NeuAc alpha 2-6Gal beta 1-4GlcNAc beta 1-3Gal beta 1-4Glc-beta 1-1'Cer. This antigen was enzymatically synthesized. Sialidase treatment of the ganglioside antigens abolished binding of HD 66 and CRIS-4.
两种单克隆抗体HD 66和CRIS - 4定义了新的CD 76 B细胞相关簇，它们可与几种不同极性的神经节苷脂（含唾液酸的糖脂）结合。HD 66识别的一种神经节苷脂可鉴定为NeuAcα2 - 6Galβ1 - 4GlcNAcβ1 - 3Galβ1 - 4Glc - β1 - 1'Cer。该抗原是通过酶促合成的。对神经节苷脂抗原进行唾液酸酶处理后，HD 66和CRIS - 4的结合被消除。
