Description

Caution

may contain precipitate (paraformaldehyde)

Principle

Formaldehyde disrupts the secondary structure of RNA and allows separation and identification of RNA species based on charge migration.

Application

Suitable for
• denaturation and separation of RNA molecules
• anti-bacterial treatment
• fixation of cells

General description

Formaldehyde is a molecular biology reagent that denaturates RNA during electrophoresis when incorporated in agarose gels.
