Development of novel measurement assay for calcium in serum by the chlorophosphonazo-III vanadate method.


Chlorophosphonazo-III (2,7-bis[4-chloro-2-phosphonophenylazo]-1,8-dihydroxy-3,6-naphthalenedisulphonic acid, disodium salt; CPZ-III) reacts with calcium and magnesium in a sample under acidic to neutral conditions. However, the specific method of measuring calcium in serum using CPZ-III has not been established because of the difficulty of avoiding the interaction between CPZ-III and albumin.
