2,3-Diaminonaphthalene is a fluorescent reagent used to detect selenium and nitric oxide (NO). 2,3-Diaminonaphthalene binds to selenium to form pyrazolene selenol, with excitation/emission maxima at 365 nm and 525 nm, respectively. 2,3-Diaminonaphthalene binds to NO2− to form the fluorescent product, 1-(H)-napthotriazole, with excitation/emission maxima at 360 nm and 440 nm, respectively.

Description

2,3-Diaminonaphthalene is a fluorescent reagent used to detect selenium and nitric oxide (NO). 2,3-Diaminonaphthalene binds to selenium to form pyrazolene selenol, with excitation/emission maxima at 365 nm and 525 nm, respectively. 2,3-Diaminonaphthalene binds to NO2− to form the fluorescent product, 1-(H)-napthotriazole, with excitation/emission maxima at 360 nm and 440 nm, respectively[1][2].

In Vitro

Poly(2,3-diaminonaphthalene) microspheres as a novel quencher for fluorescence-enhanced nucleic acid detection[1].
2,3-Diaminonaphthalene (DAN) is possibly a carcinogenic reagent[2].

[3]

Various concentrations of each drug are incubated for 60 min at 37°C in OS-mL reaction volumes containing PBS (pH 7.4), 200 μM 2,3-Diaminonaphthalene (DAN) and 40 μM Sp/NO. Spermine/NO will spontaneously decompose at pH7.4 to produce 2 mol of NO and 1 mol of spermine with a half-life of 39 min at 37°C. Following the incubation period, 2.5 mL of 10 mM NaOH is added to each tube to stop the reaction. The NO-dependent N-nitrosation of 2,3-Diaminonaphthalene to yield its highly fluorescent N-nitrosated derivative, 2,3-naphthotriazole, is quantified by measuring the fluorescence of each sample using an excitation wavelength of 375 nm and an emission wavelength of 450nm. The concentration of Triazole is determined using standards of the pure 2,3-naphthotriazole[3].

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.
