Description générale

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
Formaldehydesolution has been used:
  • 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.

Attention

may contain precipitate (paraformaldehyde)

Principe

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

Interferon-induced transmembrane (IFITM) proteins inhibit the entry of a large number of viruses. Not surprisingly, many viruses are refractory to this inhibition. In this study, we report that different strains of HIV and SIV are inhibited by human IFITM proteins

Epstein-Barr virus (EBV) causes human lymphoid malignancies, and the EBV product latent membrane protein 1 (LMP1) has been identified as an oncogene in epithelial carcinomas such as nasopharyngeal carcinoma (NPC). EBV can epigenetically reprogram lymphocyte-specific processes and induce cell immortalization.

The production of ribosomes is ubiquitous and fundamental to life. As such, it is surprising that defects in ribosome biogenesis underlie a growing number of symptomatically distinct inherited disorders, collectively called ribosomopathies. We previously determined that the nucleolar protein, NOL11
