The pregnancy-specific beta 1-globulin (SBG) reacts with 10 out of 11 lectins which have affinity to monosaccharides (glucose, mannose, galactose and fucose) and acetylamino sugars. The affinity to ConA and PHA-P was the most pronounced while this protein did not react with the pea lectin. The SBG reactions are specific for every lectin (even with the identical carbohydrate specificity). Peculiarities of the SBG reactions with lectins made it possible to reveal a few forms of this protein which differ in the carbohydrate composition and conformation of carbohydrate radicals.
妊娠特异性β1-球蛋白（SBG）与11种对单糖（葡萄糖、甘露糖、半乳糖和岩藻糖）及乙酰氨基糖具有亲和力的凝集素中的10种发生反应。对刀豆球蛋白A（ConA）和植物血凝素-P（PHA-P）的亲和力最为显著，而该蛋白不与豌豆凝集素发生反应。SBG与每种凝集素的反应都是特异性的（即使具有相同的碳水化合物特异性）。SBG与凝集素反应的特性使得有可能揭示该蛋白的几种形式，它们在碳水化合物组成和碳水化合物基团的构象上有所不同。
