Description

Application

Sodium fluoride has been used:

  • as a source of fluoride ions, to analyse its impact on spermatogenesis and capacitation in vitro
  • as an additive in the extraction buffer for the isolation of nuclei, cytoplasmic and nuclear proteins
  • as a component of lysis buffer for the lysis of human ovarian adenocarcinoma OVCAR3 cells

Biochem/physiol Actions

Sodium fluoride (NaF) prevents dental caries, by catalysing the diffusion of calcium and phosphate and remineralizes the lesions. Fluoride affects spermatogenesis and capacitation process in the female reproductive tract. Fluoride induces oxidative stress, DNA damage in ovary ultimately affects the development of oocytes. Fluoride supplementation enhances bone mineral density. 18F-NaF is a radiotracer used in positron emission tomography (PET) to identify atherosclerotic lesions and other cardiac plaques.
