| Application: | May be used for the preparation of phosphate buffered saline, and for the extraction and solubilization of proteins. |
| Application: | Potassium chloride has been used in the preparation of perfusion buffer stock solution (1X). It has been used in the preparation of the following buffers for small unilamellar vesicles (SUVs) preparation: • Escherichia coli supported lipid bilayer (SLB) buffer • extract buffer (XB) • high-salt extract buffer (HS-XB) |
| General description: | Potassium chloride (KCl) is an inorganic salt commonly used in fertilizer industry. Its generation via chlorination of microcline has been reported. The intrinsic and extrinsic conductivity of KCl crystals have been measured. The impact of KCl on the activity of mitochondrial membrane, cristae and matrix proteins has been investigated. It facilitates the preparation of isoxazolines in aqueous medium. |
