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.
