应用
用于纯化含甘露糖的糖蛋白。
生化/生理作用
刀豆素 A 无血型特异性，但对末端 α-D-甘露糖基和 α-D-葡糖基残基具有亲和力。需要 Ca2+ 和 Mn2+ 离子存在才能显示活性。刀豆素 A 在 pH 6.5 或更低的条件下解离为二聚体。pH 在 5.8 至 7.0 之间时，刀豆素 A 以四聚体形式存在；pH 高于 7.0 时，形成更高的聚合体。根据聚合程度不同，刀豆素 A 可能显示出具有促有丝分裂的活性。琥珀酰化可以生成一种能够在 pH 高于 5.6 时仍保持二聚体形式的活性二聚体。
外形
悬浮于0.1 M醋酸盐缓冲液中，pH 6.0，含有1 M NaCl以及 CaCl2、MgCl2和MnCl2各1 mM
分析说明
在报道中，凝集活性以μg/ml表示，并且是在含有1mg/mL Ca 2+和Mn 2+的磷酸盐缓冲盐水(pH 6.8)的系列稀释液中进行测定的。该活性是在25℃孵育1小时后，对2％人红细胞悬浮液进行凝集所需的最低浓度。

This study investigated the inhibitory effect of a glycoprotein isolated from Cudrania tricuspidata Bureau (CTB glycoprotein) on di(2-ethylhexyl) phthalate (DEHP)-induced mast cell degranulation and related signaling cascade in RBL-2H3 cells. This experiment evaluated the intracellular Ca(2+) level, and the activities
