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.

BG-PEG-NH2
0 ImagesSynonyms: SNAP-PEG-NH2BG-PEG-NH2 (SNAP-PEG-NH2) is an amino-terminal fluorescent probe building block and a precursor for site-specific labeling of SNAP-tag fusion proteins. BG-PEG-NH2 undergoes one-step coupling with activated carboxyl esters to form customized SNAP-tag substrates, which covalently bind to SNAP tags via a thioether bond formed at the Cys145 site. After coupling with a caged carboxyfluorescein, BG-PEG-NH2 forms a probe with Ex/Em = 500/524 nm following ultraviolet uncaging. Coupling of BG-PEG-NH2 with SeTau-647-NHS enables visualization of GPCR signal transduction. BG-PEG-NH2 is suitable for coupling reactions in aqueous phases or buffers, conjugation of labels, and labeling of intracellular or cell-surface proteins.
