Potassio cloruro

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.


  • Molecular Biology Reagent Grade
  • Presentation: White Crystalline Powder
  • Soluble in water (1 g/3 mL - clear, colorless solution), boiling water (1 g/1.8 mL), glycerol (1 g/14 mL), or ethanol (1 g/250 mL); insoluble in ether or acetone; hydrochloric acid, sodium or magnesium chlorides diminish its solubility in water.
