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.

Sulfo-Cy7.5 carboxylic acid
0 ImagesCat. No.: HY-D1866CAS No.: 2760599-02-6Sulfo-Cy7.5 carboxylic acid is a dye derivative of Cyanine 7.5 (Cy7.5) (HY-D0926) with carboxylic acid and sulfonate ion (sulfonate) functional groups. The sulfonate ion increases the water solubility of the compound, making it suitable for use in aqueous solutions. Cy7.5 is a near-infrared fluorescent dye commonly used in biomedical research areas such as biomarkers and cell imaging. Sulfo-Cy7.5 carboxylic acid can be covalently bound to some biomolecules (especially antibodies, proteins, etc.) to track their location and dynamic changes in biological samples.

DDAO phosphate diTEA
0 ImagesCat. No.: HY-D1739DDAO phosphate diTEA is an amphoteric surfactant derived from DDAO (dimethyldodecylamine oxide). The head group of DDAO in DDAO phosphate diTEA exists in a non-ionic state at pH > 7 and in a cationic state at pH < 5 due to protonation of the oxygen atom. When combined with the anionic surfactant SDS, DDAO can incorporate into mixed micelles, reducing the net micellar charge and attenuating electrostatic repulsion between SDS head groups. DDAO can be used to formulate the ONOO⁻-targeting probe DDAO-PN, which generates significant near-infrared fluorescence at 657 nm.
