General description
Formaldehyde is a molecular biology reagent that denaturates RNA during electrophoresis when incorporated in agarose gels.
It is an aliphatic aldehyde that is widely used in industrial applications for the synthesis of several chemicals such as melamine formaldehyde, urea-formaldehyde, phenol formaldehyde and industrial resins, paraformaldehyde, polyols, chelating agents, slow release fertilizers, 1,4-butanediol and hexamethylenetetramine.

Application
Formaldehyde solution is suitable for:
- denaturation and separation of RNA molecules
- anti-bacterial treatment
- fixation of cells
- in the fixation of human spermatogonial stem cell transplantation (SSCT).
- to crosslink T- cell acute lymphoblastic leukemia protein/DNA complex during chromatin immunoprecipitation.
- in fixing zebra fish larvae for neutrophil staining.
Biochem/physiol Actions
Formaldehyde disrupts the secondary structure of RNA and allows separation and identification of RNA species based on charge migration.
Disclaimer
may contain precipitate (paraformaldehyde)
