Application
来自洋刀豆（洋刀豆）的伴刀豆球蛋白 A，用于开发两性离子固定化分子印迹聚合物（ziMIPs），用于蛋白质结晶。它还用于制备载有蛋白质的微凝胶，以防止微凝胶的酶促降解，通过共聚焦激光扫描显微镜（CLSM）进行监测。
Analysis Note
凝集活动：根据 1mg/mL 溶液的连续稀释液测定（该活性是在 25℃，温育 1 小时后，凝集 2％ 人红细胞悬浮液的最低浓度）。 需要 A 型人血。
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
通过特异性亲和层析高度纯化。

The Saccharomyces cerevisiae cell surface is endowed with some relevant technological properties, notably antimicrobial and biosorption activities. For these purposes, yeasts are usually processed and packaged in an 'autolysed/dried' formula, which may have some impacts on cell surface properties. In
