生物活性

N-Aminofluorescein is a fluorescein hydrazide with spiro form, a highly selective and sensitive fluorescence probe for Cu2+. N-Aminofluorescein has no selective fluorescence response to other common metal ions, can be used for direct detection of Cu2+ in biological systems with λex/em=495/516 nm[1][2].

Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
N-Aminofluorescein consists of a fluorescein moiety and a hydrazide group to recognize and bind Cu2+, can promote the hydrolysis of amide[1].
N-Aminofluorescein (FG) shows selectivity on Cu2+ and shows the absorption and emission bands at 632 nm and 515 nm in 70% aqueous HEPES buffered solution (pH 7.4) containing Cu2+[2].
Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
General procedure for Cu2+ determination[1]:
1.Prepare the 1.0 mM stock solution of spiro form fluorescein hydrazide in ethanol;
2.Conduct the fluorescence-on reaction in 0.01 M Tris-HCl buffer (pH 7.2), with 10 μM N-Aminofluorescein;
3.Add an appropriate volume of sample solution with a final Cu2+ concentration of not more than 10 μM, and adjust the final volume 10 mL with 0.01 M Tris-HCl buffer (pH 7.2);
4.After 2 h, transfer a 3-mL portion of the solution to a 1-cm quartz cell, and measure the fluorescence intensity/spectrum at room temperature with λex/em = 495/516 nm and both excitation and emission slit widths of 5 nm;?
5.In the meantime, prepare a blank solution containing no Cu2+ and measure with the same conditions for comparison.

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.
