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.

Palladium meso-tetra(pentafluorophenyl)porphyrin
0 ImagesCat. No.: HY-W112090CAS No.: 72076-09-6Synonyms: PdTFPP; 5,10,15,20-Tetrakis(pentafluorophenyl)-21H,23H-porphine palladium(II)Palladium meso-tetra(pentafluorophenyl)porphyrin (PdTFPP) derives from palladium(II), acting as a fluorescence-quenched optical probe and high-performance oxygen concentration sensor with outstanding photostability and antioxidant capacity. Palladium meso-tetra(pentafluorophenyl)porphyrin exhibits reduced luminescence intensity as dissolved oxygen concentration rises. Palladium meso-tetra(pentafluorophenyl)porphyrin can be applied for real-time monitoring of live-cell respiration, hypoxic tissue imaging, and nanofibrous organic semiconductors in photodetectors for ambient oxygen detection.

BP Fluor 555 azide
0 ImagesCat. No.: HY-W800702CAS No.: 2770422-53-0BP Fluor 555 Azide is a water-soluble, bright orange-fluorescent dye with excitation ideally suited for the 532 nm or 555 nm laser lines and visualized with TRITC (tetramethylrhodamine) filter sets. BP Fluor 555 conjugates of antibodies, peptides, and proteins are pH insensitive from pH 4 to pH 10. AF 555 conjugates ideally suited for detection of low abundance targets. BP Fluor 555 Azide can be reacted with terminal alkynes via a copper-catalyzed click reaction (CuAAC). It also reacts with strained cyclooctyne via a copper-free “click chemistry” reaction to form a stable triazole and does not require Cu-catalyst or elevated temperatures. The brightness and photostability of this dye are best suited to direct imaging of low-abundance targets.
