Description

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.[90][92] A gel concentration of 2.2M formaldehyde is typically used. The formaldehyde concentration as supplied is approximately 13.3M.

Application

Formaldehyde solution has been used for fixing of cells and tissue sections.[94][40] It has been used in the formaldehyde agarose gel electrophoresis.[95] Formaldehyde is used as a denaturant in formaldehyde-agarose gel electrophoresis of RNA.

Packaging

25, 500 mL in poly bottle

Analysis Note

Tested for use in formaldehyde-agarose gel electrophoresis of RNA.
