Description

Potassium chloride is a salt commonly used in the preparation of phosphate buffered saline and for the extraction and solubilization of proteins. It is a good potassium source. Also used in the hypotonic KCl-propidium iodide protocol for univariate analysis of metaphase chromosomes ; dissociation of eukaryotic ribosomes into subunits by high concentrations of potassium (0.3-1.0 M); preparation of mitochondria, provides an ionic osmotic support for those tissues that assume a gelatinous consistency upon homogenization.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
