Descripciòn

NBD-Cl is a nonfluorescent reagent which becomes highly fluorescent after reaction with thiol or amino groups[1].

In Vitro

NBD-Cl (NBD chloride) forms highly fluorescent derivatives for detection of all the protein amino acids. In addition, NBD-Cl provides a simple and sensitive method for determination of N-terminal amino acids. The differences in intensity and color of fluorescence can be used to advantage to identify prolyl peptides[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (12.53 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Fluorescence Measurements[1]
Fluorescence spectra are recorded on a Hitachi MPF-24 Fluorescence Spectrophotometer. The emission spectrum is determined at the optimal wavelength of 464 nm. Thin-layer chromatography is carried out on Brinkmann glass supported analytical silica G thin-layer plates without fluorescent indicator. The NBD derivatives are visualized on thin-layer plates either by examination under an ultraviolet lamp with a long wavelength filter or by using the same lamp with a 2×2-in. Corning 5-57 filter and viewing the spots through a 2×2-in. Corning 3-68 filter. The former method produces a more intense fluorescence, but the latter produces a much greater contrast appearing as white spots against a dark background. NBD-Cl (NBD chloride) is allowed to react with amino acids and peptides under the conditions. Into 3 mL Pyrex test tubes are pipette the following: (1) 2.0 mL of ethanol, (2) 0.1 mL NBD-Cl solution in ethanol 1.41 pg/mL, (3) 0.1 mL ethanol saturated with sodium acetate, (4) 0.1 mL of amino acid solution 400-600μg/mL, and the mixture incubated at 75°C for 20 min. For reaction with peptides, 1.5 mL of ethanol, 0.1 mL ethanolic sodium acetate, 0.4 mL ethanolic NBD-Cl, 1.41 μg/mL, are added to 0.4 ml of the peptide and incubated under the same conditions.

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.
