General description
10%中性缓冲的甲醛（NBF）是全世界范围内用于光学显微镜最常使用的固定剂，并且也是一种较为宽容的固定剂。10% NBF很适合于高通量的实验室，并只需要一段相对短的固定时间，但也可用于组织的长期储存。甲醛固定被视为在醛和蛋白之间形成的，并生成凝胶，从而在它们的体内关系上保留细胞性组成。一旦被正确固定后，组织应该可以承受后续的组织处理或染色阶段。
Application
10%甲醛中性缓冲溶液已用于3T3-L1前脂肪细胞系及小鼠胚胎成纤维细胞分化至脂肪细胞的油红-o染色。它已用于兔眼及糖尿病大鼠肠的组织学分析。
10%甲醛中性缓冲溶液已被用作一种常用的通用组织固定剂用于对组织进行固定。
