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.

M-H2S
0 ImagesCat. No.: HY-D3003CAS No.: 2522921-17-9M-H2S is an endoplasmic reticulum-targeted ratio-type near-infrared fluorescent probe (Ex/Em : 480 nm/560 nm) specifically designed for the detection of hydrogen sulfide (H2S) in living cells and zebrafish. M-H2S exhibits detection limit for H2S of 39.1 nM, and the fluorescence intensity ratio (F₆₅₀/F₅₆₀) within the range of 0-40 μM shows a linear relationship with the H2S concentration. M-H2S responds best under pH = 7.2 (the normal physiological pH of the endoplasmic reticulum) conditions, making it suitable for the detection of the microenvironment of the endoplasmic reticulum. M-H2S can be used to study the role of H2S in endoplasmic reticulum function, stress response, and related diseases.

Coelenteramine 400a hydrochloride
0 ImagesCat. No.: HY-118462ACAS No.: 2320429-05-6Synonyms: Coelenterazine 400a hydrochloride; Bisdeoxycoelenterazine hydrochlorideCoelenteramine (Coelenterazine) 400a hydrochloride, a derivative of Coelenterazine, is a Renilla luciferase (RLuc) substrate. In the presence of Coelenteramine 400a hydrochloride, RLuc can emit blue light at 395 nm. Coelenteramine 400a hydrochloride will causes color change in the bioluminescence reaction of Rluc by replacing the sulfur and oxygen heteroatoms of the methylene bridge. Coelenteramine 400a hydrochloride provides higher signal resolution and can be used in the research of bioluminescence resonance energy transfer (BRET).
