Chlorophosphonazo III is a sensitive reagent for both calcium and magnesium. It is possible to determine calcium alone at pH 2.2 and calcium and magnesium at pH 7.0. Chlorophosphonazo III can also be used for the spectrophotometric determination of titanium, zirconium, thorium, and scandium, quinquevalent actinide elements, and protactinium.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
