General description

Sodium phosphate monobasic serves as a source of phosphate ions. The use of sodium phosphate monobasic to correct severe hypophosphatemia conditions has been reviewed.

Application

Sodium phosphate monobasic solution has been used as a component of aCSF (artificial cerebrospinal fluid) stock solution for use in the patch-seq analysis of small interneurons. It has also been used as a supplement in the preparation of crude extract of cells for decentralizing cell-free RNA sensing.

Protocols

Enzymatic Assay of Alcohol Dehydrogenase (EC 1.1.1.1)

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

Enzymatic Assay of Hyaluronidase (3.2.1.35)

To measure hyaluronidase activity, a turbidimetric determination assay is used at 600 nm. One unit of hyaluronidase activity will cause a change in absorbance of 0.330 per minute at pH 5.35 at 37 °C.
