描述

Analysis Note

据报道,凝集活性以 μg/ml 表达,并且在 Ca2+ 和 Mn2+ 浓度为 1mg/ml、pH 6.8 的磷酸缓冲盐溶液中进行连续稀释测定。该活性是在 25°C 下孵育 1 小时的 2% 人红细胞悬浮液可以凝集的最低浓度。

Biochem/physiol Actions

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。

Preparation Note

Produced from whole Jack beans (J0250) using acetic acid by the method of Olson and Liener.1

Quality

Highly purified.
