Application

Potassium fluoride may be used in thermodynamic analysis of DNA-ligand binding and studies on the structural stability of proteins and peptides.
A versatile fluoride ion source used in a study of ion-specific swelling and de-swelling of ampholytic polymer gels, in the room temperature oxidation of noble metals in HF, and in the measurement of electronic polarizabilities of ions in polymers of alkali halides.

Other Notes

Inhibitor of pyrophosphatase, hence prevents loss of ATP by hydrolytic cleavage of the pyrophosphate bond in the assay of amidophosphoribosyltransferase; Strongly inhibits polypeptide chain initiation in the reticulocyte lysate cell-free system
