一般描述

凝集素是糖类结合蛋白，广泛存在于真菌、植物和动物中。凝集素的二级结构富含 β-链，表面具有糖类结合位点。

应用

用于纯化含有（D-N-乙酰氨基葡萄糖）2或N-乙酰神经氨酸的糖蛋白。

生化/生理作用

凝集素可用于鉴定、成像和靶向糖缀合物。与寡糖、糖蛋白和糖脂发生特异性相互作用。因此，凝集素用于微阵列测定，可实现有效的糖组谱分析。在植物和真菌内部，凝集素可抵御病原体或寄生物（feeder）侵袭。还参与宿主识别和组织粘附。
WGA 不具有血型特异性，但具有与 N-乙酰基-β-D-葡糖胺残基和 N-乙酰基-β-D-葡糖胺低聚物的亲和性。WGA 不含蛋白结合糖。

外形

悬浮于含15 mM叠氮化钠的1.0 M NaCl溶液中

制备说明

由亲和纯化凝集素制备偶联物。

Stem cells undergo cytokine-driven differentiation, but this process often takes longer than several weeks to complete. A novel mechanism for somatic stem cell differentiation via phagocytosing 'model cells' (apoptotic differentiated cells) was found to require only a short time frame.
