生物活性

Hydroxy naphthol blue disodium, an azo dye, is a metal indicator for calcium and a colorimetric reagent for alkaline earth metal ions ( λmax = 650 nm). In the pH range between 12 and 13, the solution of the indicator is reddish pink in the presence of calcium ion and to deep blue in the presence of disodium EDTA[1].

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.
