General description

Potassium chloride (KCl) is useful in studies of ion transport and potassium channels.[1] KCl is known to be used in the crystallization of histone core octamers.[2]

Application

Potassium chloride has been used:
  • as a component of Danieau medium and also used in the preparation of phosphate buffer saline[3]
  • in the preparation of electrolyte solution for electrochemical impedance spectroscopy and cyclic voltammetry measurements[4]
  • as a component of HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid)-buffered Tyrode′s solution[5]

May be used for the preparation of phosphate buffered saline, and for the extraction and solubilization of proteins.
