应用
用于荧光检测含有 α−-D-甘露糖或 α−-D-葡萄糖的糖蛋白
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。

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。

Noninfectious (autoimmune and immune-mediated) uveitis is an ocular inflammatory disease which can lead to blindness in severe cases. Due to the potential side effects of first-line drugs for clinical uveitis, novel drugs and targets against uveitis are still urgently needed.

Cell-cell or cell-substrate interactions are lost when cells are dissociated in culture, or during pathophysiological breakdowns, therefore impairing their structure and polarity, and affecting their function. We show that single rat β-cells, cultured under non-adhesive conditions, form intracytoplasmic vacuoles increasing

The toll-like receptor 5 (TLR5) agonist, CBLB502/Entolimod, is a peptide derived from bacterial flagellin and has been shown to protect against radiation-induced tissue damage in animal models. Here we investigated the protective mechanism of CBLB502 in the liver using models
