一般描述
太平洋牡蛎/Crassostrea gigas 是重要的海洋渔业资源。牡蛎干重的 20-40% 含有糖原。高水平的糖原有助于维持牡蛎的风味、品质和耐寒性。
糖原是一种葡萄糖多糖,是葡萄糖在体内的主要储存库,在真菌和动物中都是重要的能量储备。糖原具有多分支结构,与淀粉相似,是二级长期储能分子,与支链淀粉密切相关,在能量储存和释放中起关键作用,以颗粒形式存在于细胞质中。
研究中,糖原通常用于研究碳水化合物的储存、代谢和酶特性。作为惰性载体,可显著提高乙醇沉淀法提取DNA和RNA的效率。它的多用途性对于揭示葡萄糖循环的复杂细节方面很有价值,有助于推动生理、营养、生化和细胞生物学研究各领域的发展。

糖原是动物细胞合成的用于能量储存和释放的葡萄糖支链聚合物。其主要由α1→4糖苷键构成,通过α1→6糖苷键产生分支。
应用
来自牡蛎的糖原已用于:
- 用作丙烯酰胺平板凝胶成分,进行分支酶活性染色定量 ADP-葡萄糖焦磷酸化酶 (AGPase) 活性
- 用作无菌炎症剂,接种到小鼠体内以获得腹膜渗出细胞 (PEC) ,研究其对巨噬细胞代谢功能的影响
- 用作补充马来酸缓冲液的引物,用于淀粉蔗糖酶测定,测量谷胱甘肽 S-转移酶 (GST-AS) 淀粉蔗糖酶融合蛋白的活性和纯化组分
- 作为 PreScission 缓冲液的补充剂,进行聚合物合成反应
牡蛎糖原经腹腔注射后被用于诱导炎症 和促进动物模型粒细胞 和中性粒细胞 的外渗。糖原也可作为血管通透性探针。
特点和优势
- 非常适合生物学和生化研究
- 用途广泛,适用于各种实验室和研究应用。

A macrophage cell-surface antigen associated with pyran and Corynebacterium parvum-activated macrophages and P388D1 cells but not detectable on normal or glycogen and thioglycollate-elicited murine macrophages has been described. The antigen was demonstrated both by complement-mediated cytotoxicity and immunofluorescence, using an
