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.[16]

Application

Potassium chloride has been used:
  • to prepare phosphate buffer saline for phosphate calcium transfection
[63]
  • as a component of lysis buffer used for the isolation of cytosolic and nuclear proteins
  • [70]
  • to prepare phosphate buffer saline used for protein isolation from gram-positive bacteria
  • [46]
    May be used for the preparation of phosphate buffered saline, and for the extraction and solubilization of proteins.
