一般說明

凝集素是植物来源的蛋白质,具有与某些神经元表面糖蛋白和糖脂结合的能力。它们的这种能力帮助它们被用作神经解剖示踪剂,因为它们以逆行或顺行的方式摄取和运输。

應用

来自 兵豆的凝集素用于使用 ANA 进行基于大小或电荷的蛋白质分离。(各向异性纳米过滤器阵列:ANA)。

生化/生理作用

LcH 不具有血型特异性。对末端 α-D-甘露糖基和 α-D-葡萄糖基残基有亲和力。LcH 由两种异构体组成,LcH-A(分子量 49,000)和 LcH-B(分子量 49,000)。LcH-A 具有促有丝分裂活性。结合物由纯化的凝集素制备。

品質

含有电泳上相应的于同工凝集素 LcH-A 和 LcH-B 的两条主带。

準備報告

通过亲和层析高度纯化。

分析報告

凝集活性以 μ 表示g/mL,通过在 pH 6.8 磷酸盐缓冲盐水中连续稀释 1 mg/mL 溶液测定。该活性是在 25°C 下孵育 1 h 后凝集 2% 人红细胞悬液的最低浓度。
