General description
凝集素存在于数种植物和某些动物中。它是由相同亚单位组成的一种四聚体。
Application
凝集素已被用于差异化铺板，以从分离的细胞群体中分离出塞尔托利氏细胞。它还可被用于精原干细胞的差异化铺板。
Biochem/physiol Actions
凝集素可识别并结合延伸自糖脂和糖蛋白的碳水化合物复合体。它还可结合自由浮动的聚糖，如单糖。
DSL 不是血型特异性的，但对 N-乙酰基葡萄糖胺和 N-乙酰基乳糖胺的低聚物具有亲和力。凝集素是一种糖蛋白，含有约 35％ 的碳水化合物。
Preparation Note
通过亲和层析纯化
Analysis Note
凝集活性以 μg/ml 表示，由 1 mg/ml 在磷酸盐缓冲盐水（pH 6.8）中的系列稀释液而测得。该活性是指 25℃ 孵育 1 小时后使 2％ 人红细胞悬浮液凝集的最低浓度。
高度纯化。

Sertoli cells are somatic cells in testis essential for spermatogenesis, that support the development, maturation, and differentiation of germ cells. Sertoli cells are metabolically highly active and physiologically regulated by external signals, particularly factors in the blood stream. In disease
