Phosphorus

Intended use
Biostep phosphorus reagent is intended for the invitro quantitative, diagnostic determination of phosphorus in human serum and urine on both automated and manual systems.
Background
In plasma or serum, most phosphate exist in the inorganic form (Pi): this fraction is present as the mono-and dihydrogen forms, the relative proportions varying with the PH. Intracellularly, phosphate occurs mainly as phospholipids and phosphoproteins; this fraction is termed organic phosphate.
