Description

Application

Sodium chloride has been used:
• as a component of buffer solution to prepare the pH solutions for open-circuit potential and cyclic voltammetry
• in the preparation of Bold’s basal medium (BBM)
• as a component of transcription and annealing buffer

Biochem/physiol Actions

Sodium chloride helps to stimulate the stable induction of T-helper cell 17 (TH17) cells.
