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.

Dnp-RPLALWRS
0 ImagesCat. No.: HY-P3123CAS No.: 172666-82-9Dnp-RPLALWRS is a fluorescent peptide substrate designed for human matrilysin (MMP-7). After enzymatic cleavage of Dnp-RPLALWRS at the alanine-leucine bond, the release of the Dnp group alleviates fluorescence quenching, thereby enabling real-time quantitative analysis of MMP-7 activity by increasing tryptophan emission. Dnp-RPLALWRS provides a sensitive and efficient detection method for kinetic studies and inhibitor screenin.

Acid blue 1 free acid
0 ImagesSynonyms: Xylene blue free acid; C.I. Acid blue 1 free acidAcid blue 1 free acid (Patent Blue V) is a novel biological dye that can be used as an intraocular dye for retinectomy. Retinectomy refers to the removal of the translucent inner limiting membrane (ILM). The application of appropriate dyes in vitreoretinal surgery can achieve the purpose of complete removal. Acid blue 1 free acid can be used to stain retinal premembranous structures. Spectral analysis shows that Acid blue 1 free acid has strong absorption below 450 nm and above 600 nm, showing a blue-green color. Acid blue 1 free acid is also used as a marker in lymphangiography for resection of neoplastic lymph nodes.
