Beschreibung

Application

Eine vielseitige Fluoridionenquelle für Studien ionenspezifischer Quellung und Entquellung ampholytischer Polymergele , Raumtemperatur Oxidation von Edelmetallen in HF und bei der Messung der elektronischen Polarisierbarkeit von Ionen in Polymeren von Alkalimetallhalogeniden.

Potassium fluoride may be used in thermodynamic analysis of DNA-ligand binding and studies on the structural stability of proteins and peptides.

Other Notes

Inhibitor of pyrophosphatase, hence prevents loss of ATP by hydrolytic cleavage of the pyrophosphate bond in the assay of amidophosphoribosyltransferase[1]; Strongly inhibits polypeptide chain initiation in the reticulocyte lysate cell-free system[2]
