Phalloidin is a mushroom-derived toxin which can be used to label F-actin of the cytoskeleton with fluorochrome (λex=495 nm, λem=520 nm). Phalloidin staining will not work with methanol-fixed cells, probably because of the disruption of actin filament integrity, but it will work with cells fixed in 0.2% glutaraldehyde in PBS. For fluorescein isothiocyanate (FITC)-Phalloidin (or rhodamine isothiocyanate [RITC]-Phalloidin), the excitation wavelength maximum will be near 495 nm (or 550 nm) and the emission wavelength maximum will be ~520 nm based on H2O at pH 8.0 as the solvent (575 nm with methanol as the solvent). The emission spectrum of fluorescein can depend on the environmental pH and/or ionic strength.

| Copper probe CF4
Copper probe CF4 (Copper fluor CF4) is a Cu+-specific fluorescent probe based on a rhodol dye scaffold. Copper probe CF4 (Copper fluor CF4) has high copper selectivity with a Kd value of 2.9×10-13 M, particularly over zinc and iron, as well as abundant cellular alkali and alkaline earth metals. Copper probe CF4 (Copper fluor CF4) is stable in a physiologically relevant pH regime between 6 and 8 (wavelengths of 415 nm for excitation and 660 nm for emission). Copper probe CF4 (Copper fluor CF4) can be used to study colon cancer. |
| Phalloidin-Fluor 647 Conjugate
Phalloidin-Fluor 647 Conjugate selectively binds to F-actins. Used at nanomolar concentrations, phalloidin derivatives are convenient probes for labeling, identifying and quantitating F-actins in formaldehyde-fixed and permeabilized tissue sections, cell cultures or cell-free experiments. |
| HBC530
HBC530 is a GFP fluorophore-like synthetic dye, with a structurally rigid electron acceptor and a strong electron donor. HBC is nonfluorescent in solution, and when combined with Pepper (RNA aptamer), HBC forms a tight complex and activates and emits bright fluorescence (Kd of ~3.5 nM). HBC emission peaks vary in different complexes and covers the spectrum from cyan to red. HBC can be used in the live cell imaging of RNA (Em/Ex = 530/485 nm). |
| 2',7'-dichlorodihydrofluorescein
2,7-Dichlorodihydrofluorescein (DCFH2) is a non-fluorescent reactive oxygen species (ROS) probe with an excitation wavelength of 485-500 nm and an emission wavelength of 515-530 nm. 2,7-Dichlorodihydrofluorescein is first hydrolyzed by intracellular esterases and then oxidized by ROS to generate non-biomembrane-permeable, highly fluorescent 2,7-dichlorofluorescein (DCF). 2,7-Dichlorodihydrofluorescein can undergo oxidation reactions with a variety of ROS (such as ·OH, H2O2, ONOO-, etc.) and is used to quantitatively detect the level of oxidative stress inside and outside cells. The fluorescence intensity of DCF is positively correlated with the ROS concentration. |
| 4-MUNANA
4-MUNANA is a substrate of influenza virus neuraminidase (NA) with high selectivity and irreversible reaction. In the enzymatic reaction, 4-MUNANA is hydrolyzed by NA to generate fluorescent 4-methylumbelliferone (4-MU). By detecting the fluorescence intensity of 4-MU, quantitative analysis of NA activity can be achieved. |
