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-Mln
0 ImagesCat. No.: HY-D3127CAS No.: 455251-97-5DCA-Mln is a Fluorescent probe for ferric iron (Fe³⁺) detection. The probe works via an internal charge transfer (ICT) process from its diethylamino group to its dicyano group, which produces bright pink fluorescence in its unbound state; when Fe³⁺ is present, two molecules of DCA-Mln chelate with one Fe³⁺ ion, with one cyano group of each DCA-Mln participating in the complexation, and this binding triggers a photoinduced electron transfer (PET) process that provides a nonradiative deactivation pathway, resulting in fluorescence quenching; additionally, the probe exhibits a visible color change from purple to peach pink upon Fe³⁺ binding, enabling dual-channel detection. The probe has an excitation wavelength of 570 nm and an emission wavelength of 670 nm, and it shows a rapid response, with fluorescence stabilizing within 15 seconds of Fe³⁺ addition. DCA-Mln is cell-membrane-permeable, nontoxic at the imaging concentration of 10 μM, and can be used for Fe³⁺ detection in actual water samples, Fe³⁺ imaging in living cells, and as an anti-counterfeiting ink[1].

Spring red
0 ImagesCat. No.: HY-D3132CAS No.: 1616505-01-1Spring Red is a fluorescent probe for mitochondrial pH detection (Ex/Em = 530/680 nm) that can be taken up by live cells and mitochondria. The detection mechanism of Spring Red depends on pH changes and mitochondrial membrane potential. Fluorescence intensity increases with elevated pH, and a significant pH-dependent fluorescent response is observed in the pH range of 5.0‑8.0. Spring Red is suitable for long-term live-cell imaging and in vivo imaging, and can be used to monitor dynamic mitochondrial pH changes.

Evans Blue Staining Solution (0.5%)
0 ImagesCat. No.: HY-DY20240.5% Evans Blue Staining Solution is an azo dye solution that strongly binds to serum albumin to form a high-molecular-weight tracer complex. 0.5% Evans Blue Staining Solution can passively leak with albumin and produce color when the blood-brain barrier or vascular barrier is damaged in vivo, and it is used for permeability assessment. 0.5% Evans Blue Staining Solution is excluded by living cells but enters dead cells to stain them in vitro due to the loss of membrane integrity in dead cells. 0.5% Evans Blue Staining Solution can be used for studies related to the identification of dead/necrotic cells and blood-brain barrier (BBB) permeability.

CR-1
0 ImagesCat. No.: HY-D3080CR-1 is a ratiometric photoacoustic (PA) probe for in-situ real-time imaging of Zn2+ in deep living tissues. CR-1 is formed by coupling the near-infrared cyanine dye IR825 with the Zn2+ ligand tris (2-pyridylmethyl) amine (TMPA). Upon binding to Zn2+, the five N atoms on TMPA coordinate with Zn2+, leading to double bond rearrangement of IR825 and attenuation of its π-electron conjugated system. The absorption peak of CR-1 blue-shifts from 710 nm to 532 nm, enabling quantitative detection of Zn2+ via the PA532/PA710 ratio. Free CR-1 generates a strong PA signal at 710 nm, while CR-1 bound to Zn2+ produces a strong PA signal at 532 nm.
