Fluorescent Dye
Fluorescence is a phenomenon of photoluminescence in luminescence. When an atom is irradiated by light, some electrons around the nucleus jump from their original orbitals to higher energy orbitals under the influence of light energy, i.e., from the ground state to the first or second excited single-line state, etc. Due to the instability of the first or second excited singlet state, the electron returns from the excited singlet state to the ground state accompanied by released energy, resulting in fluorescence.
Fluorescent dyes can be covalently bound or physically adsorbed in the structure of the substance. The fluorescence properties allow for the characterization, localization and quantitative analysis of the labeled object. Fluorescent dyes have shown great potential for the detection of proteins, nucleic acids, cells, and immunoassays, attributed to the advantages in non-radioactive contamination, simple experimental operation and easy observation.
Fluorescent dyes have penetrated many fields such as pharmacology, physiology, environmental science, and information science, as well as functional studies of proteins and drug screening.

DCA
0 ImagesCat. No.: HY-D3105DCA is a Fluorescent probe for visualization of phase behavior in ER membranes. DCA is an ER-targeting, polarity-responsive NIR ratiometric probe, with its p-toluenesulfonamide group responsible for ER localization; its sensitivity to polarity relies on its donor-π-acceptor (D-π-A) structure, where aniline acts as the donor and dicyanomethylene acts as the acceptor, driving an intramolecular charge transfer (ICT) process upon excitation. In environments with low polarity, such as the closely packed, low water content ERₒ phase of ER membranes, DCA emits at a shorter wavelength, while in high polarity environments like the loosely packed, higher water content ERd phase, ICT leads to a red-shifted emission, allowing discrimination of the two phases via dual NIR emission colors and ratiometric imaging. Ex/Em = 488/570–620 nm and 488/665–735 nm; additional excitation/emission pairs include Ex/Em = 488/631 nm in low polarity 1,4-dioxane and Ex/Em = 488/677 nm in 1,4-dioxane with 30% water, the higher polarity condition. It shows a large Stokes shift of ~170 nm, and pH, viscosity, and biologically relevant species including Cys, GSH, H₂O₂, and metal ions do not exert marked interference on its fluorescence spectra[1].
