Description

General description

Potassium chloride (KCl) is useful in studies of ion transport and potassium channels.[53] KCl is known to be used in the crystallization of histone core octamers.[29]

Application

Potassium chloride has been used:

• as a component of Danieau medium and also used in the preparation of phosphate buffer saline

[39]

in the preparation of electrolyte solution for electrochemical impedance spectroscopy and cyclic voltammetry measurements

[31]

as a component of HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid)-buffered Tyrode′s solution

[32]

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