Descrição geral

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

Aplicação

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

Embalagem

250, 250 mL
1, 2.5 L

Atenção

may contain precipitate (paraformaldehyde)

Princípio

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