General description

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


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
