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. 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. It has been used in the formaldehyde agarose gel electrophoresis. 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.
