甲醛溶液，中性缓冲，10%，19L，HT501640-19L，Sigma

General description

10%福尔马林中性缓冲液通常用作已被用作光学显微镜的固定剂。它需要相对较短的固定时间。它适用于长期储存组织。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。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。福尔马林通过让蛋白质分子交联形成凝胶而固定，使细胞保持生活状态时的形态结构。

Application

10%中性福尔马林溶液是备受欢迎的通用组织学固定剂。通过防止组织腐败、维持其分子结构来保存组织样本。
常用的通用组织学固定剂。

Biochem/physiol Actions

Formaldehyde is both a non-coagulant and an additive fixative. Formalin fixation is thought to form cross links between the aldehydes and the proteins, creating a gel, thus retaining cellular constituents in their in vivo relationship. Formaldehyde is known to penetrate tissue quickly, but the fixation process may take a long time to form the various cross links with tissue proteins.

Features and Benefits

• 10% NBF is well-suited for large throughput laboratories.
• It requires a relatively short period of fixation.
• It can be used for the long-term storage of tissue.

Packaging
