Chromogenic reactive for determining the iron content and the iron-binding capacity of biological liquids.

摘要

The present invention relates to a chromogenic reactive for determining the iron content and the iron-binding capacity of serum, comprising chromazurol B, a buffer for keeping the pH at 4.5-5, a surface-active substance in a concentration of at least 500 mg/l, a salt suitable for imparting an ionic strength expressed in terms of NaCI concentration of at least 100 g/l and an aminoacid suitable for selectively binding the Cu2+ ions, in a concentration expressed in terms of glycine concentration ranging between 1 and 40 g/l.
