名称 | 聚乳酸-羟基乙酸共聚物，聚丙交酯-乙交酯，PLGA |
英文名 | poly(lactic-co-glycolic acid)，Poly(ctide-co-glycolide) |
同用名 | 聚丙交酯-乙交酯, 聚乳酸－聚羟基乙酸，丙交酯-乙交酯共聚物，聚乳酸-羟基乙酸共聚物，poly(lactic-co-glycolic acid)，Poly(ctide-co-glycolide)，PLGA |
基本描述 | 聚乳酸-羟基乙酸共聚物（poly(lactic-co-glycolic acid)，PLGA）是一种降解速率可调的可降解高分子有机化合物，是聚乳酸（PLA）和聚羟基乙酸（PGA）的无规共聚物，化学式为[C3H4O2]m[C2H2O2]n，由一定比例的乙交酯（LA）和丙交酯（GA）两种单体通过开环聚合而成。PLGA具有良好的生物降解性、生物相容性、无毒、良好的成囊和成膜的性能，被广泛应用于制药、医用工程材料和现代化工业领域。由于LA和GA的降解速率存在明显区别，因此可以通过调节LA与GA的投料比而获得不同降解时间的共聚物。商品化PLGA医用产品包括可吸收手术缝合线、药物载体、骨钉骨板、血管支架等。PLGA的良好力学性能、易加工性能及支持细胞粘附和生长作用，使它具有潜在的组织工程和再生医学应用性，可用于组织或器官的3D支架。而其体内可降解性和降解速率可调的特性，使其普遍适用于人体不同组织、器官的再生与修复需要。因此，PLGA也是一种理想的再生医学材料。

三、使用方法：
（一）玻片涂膜（用于细胞培养）
1、取一定量聚合物溶于氯仿，制成0.1%聚合物溶液。为获得均质薄膜，溶解过程中需搅拌子搅拌或超声处理20－30min，以确保聚合物完全溶解。
2、取10－30ul聚合物溶液，滴加在硅化玻片表面，快速推片或拉片涂膜，常温下自然干燥30min，真空干燥6－12h。
3、置于多孔板中，紫外照射10－15分钟，或臭氧熏蒸30分钟后用于细胞培养。
4、根据研究目的不同，还可对玻片表面的聚合物薄膜进行表面修饰处理。不同组别可设置3－5个平行样，以便进行定量分析。
5、其它研究方法可参照文献进行。
