Analysis Note

针对用于 RNA 的甲醛-琼脂糖凝胶电泳进行了测试。

包装

25, 500 mL in poly bottle

Application

Formaldehyde solution has been used for fixing of cells and tissue sections.^[3][4] It has been used in the formaldehyde agarose gel electrophoresis.^[5]

General description

Formaldehyde (formalin) is produced by oxidation of methanol. It is made of 37% formaldehyde and impurities such as methanol, small amounts of formic acid, aldehydes and ketones. It is used as a denaturant in formaldehyde-agarose gel electrophoresis of RNA.^[1][2] A gel concentration of 2.2M formaldehyde is typically used. The formaldehyde concentration as supplied is approximately 13.3M.
