General description

Sodium phosphate monobasic acts as an acidulant in laxatives and effervescent powders. It is used in beverages, cheese and soft drink formulations.

Application

Sodium phosphate monobasic has been used:
  • as a reagent for virus transfection and fiber implantation in mouse
  • in phosphate buffer for immunocytochemistry and to detect individual catalase activity by PAGE (polyacrylamide gel electrophoresis)
  • as a buffer for cycling assay
  • in automated DNA extraction method
  • as a chemical in artificial cerebro-spinal fluid (aCSF) solution for the preparation of brainstem-spinal cord from rats
