The temperature used for standard tissue processing historically has been room temperature. Temperature can affect the rate of fixation, and modern tissue processors may use elevated temperatures to reduce processing time without adverse effects on tissue morphology. Cold fixation is common in electron microscopy when using glutaraldehyde as a fixative.

一般說明
甲醛（HCOH）是最熟悉和有效的固定剂之一。甲醛固定几乎适用于所有类型的组织学组织，以及钙化沉积物、骨、软骨、神经系统标本。人或动物来源的组织学标本材料的固定通常在4％或10％甲醛溶液中进行。化学上，4%甲醛溶液等于10%福尔马林溶液。这种甲醛溶液4%是一种即用型工作溶液，用磷酸盐缓冲液稳定以保护组织结构。甲酸的发展将得到有效的预防。它是IVD注册和CE认证的产品，可用于诊断目的。有关详细信息，请参阅使用说明 （IFU）。IFU 可以从本网页下载。

The hijacking of cellular function through expression of proteins that interfere with the activity of cellular enzymes and regulatory complexes is a common strategy used by viruses to remodel the cell environment in favor of their own replication and spread.

Do 4% formaldehyde or 10% formalin solutions contain traces of methanol?
1 answer-
Product 1004960700 and all other formaldehyde or formalin solutions contain methanol to prevent the formaldehyde from reforming as a polymer or escaping as a gas. If a methanol-free solution is required, paraformaldehyde powders or crystals can be purchased and prepared into methanol-free solutions, although these solutions are unstable and should be prepared fresh daily or kept for only short periods of time.
