Analysis Note

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。

Application

用于荧光检测含有 α−-D-甘露糖或 α−-D-葡萄糖的糖蛋白

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。

Fisher's fundamental theorem of natural selection predicts no additive variance of fitness in a natural population. Consistently, studies in a variety of wild populations show virtually no narrow-sense heritability (h2) for traits important to fitness. However, counterexamples are occasionally reported
