Application

Sodium phosphate dibasic solution has been used:
  • to supplement Dulbecco′s Modified Eagle Medium (DMEM) in calcifying medium to induce the calcification of vascular smooth muscle cells (VSMCs)
  • to prepare a stock solution of CaCl2 and MgCl2 to synthesize calcium phosphate (CPB) and magnesium phosphate bions (MPBs) respectively
  • to supplement 2xYT agar plates to culture BL21 DE3 star cells and BL21dLac Gold cells

Sodium phosphate dibasic solution may be used in the preparation of a wide variety of phosphate based biological buffers for use in cell and molecular biology application.

Protocols

To measure alcohol dehydrogenase activity, this assay uses β-nicotinamide adenine dinucleotide phosphate and a continuous spectrophotometric rate determination at 340 nm.

This procedure may be used for Hyaluronidase products.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
