生物活性

Pyranine (HPTS; Solvent Green 7) is a pH-sensitive fluorescent indicator. Pyranine acts as a class of fluorescent chemosensor for the Cu+ ion(λex=450 nm, λem=510 nm)[1][2][3].

体外研究
(In Vitro)

Pyranine is capable of discriminating ranges of cations from the Cu+ ion, even in competing environment. Pyranine displays a rapid fluorescence response (t1/2=1.66 min) towards the Cu+ ion, and the micromolar detection limit enables the detection of the ion in environmental samples. The observed stoichiometry of complexation between Pyranine and Cu+ is 2:1[1].
The pH-sensitive fluorescent indicator Pyranine is studied to determine its usefulness as probes for the living cornea and anterior chamber. Adequate concentrations are reached in the cornea and anterior chamber after topical administration; measurements can be made by fluorophotometry for many hours. The pH is calculated by measuring the ratio of fluorescent intensity at two excitation wavelengths, I463/I404, a measurement which is dependent on pH but independent of the concentration of the fluorophore and other variables which can alter the intensity. In the rabbit eye, Pyranine in the cornea and anterior chamber is observed to undergo easily measurable changes in fluorescent ratios associated with lid closure and contact lens wear, indicating its sensitivity to mild changes in pH[2].

[3]

PAAm-κC composite gels are prepared by free-radical copolymerization using 0.71 g of AAm, 0.01 g of BIS (N, N’-methylenebisacrylamide), 0.008 g of APS (ammonium persulfate) and 2 µl of TEMED (tetramethylethylenediamine) are dissolved in 5 mL of distilled water (pH 6.5) by heating. The heated mixture solution is held at 80°C. Then different amounts of κ-carrageenan (0.5, 1, 1.5, 2, 2.5 and 3 (w/v) % κC) are added. Pyranine (Py) is used in the PAAm–κC composites as a fluorescence probe, which is a derivative of pyrene possessing three SO3- groups, which can form bonds with positive charges on the gel. Pyranine (Py) concentration is kept constant at 4×10-4 M, for all experiments. The solution is stirred (200 rpm) for 15 min to achieve a homogenous sample solution. All samples are deoxygenated by bubbling nitrogen for 10 min just before the polymerization process. The drying and swelling experiments of disc-shaped PAAm–κC composite gels prepared are performed in air and in water, respectively, at various temperatures (30, 40, 50, and 60°C). A model LS-50 spectrometer equipped with a temperature controller is used for fluorescence intensity measurements, which are made at a 90° position and spectral bandwidths are kept at 5 nm. Disc-shaped gel samples are placed on the wall of a 1-cm path-length square quartz cell filled with air and/or water for the drying and swelling experiments[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.
