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.

    BP Fluor 405 picolyl azide
    BP Fluor 405 Picolyl Azide is an advanced fluorescent probe that incorporatess a copper-chelating motif to raise the effective concentration of Cu(I) at the reaction site. The rate of the CuAAC reaction depends on the concentrations of all reagents, including copper, therefore raising the effective copper concentration at the reaction site dramatically increases the rate of CuAAC reaction without increasing the concentrations of azide reagent or copper. In addition, the use of picolyl azide instead of conventional azides allows for at least a tenfold reduction in the concentration of the copper catalyst without sacrificing the efficiency of labeling. In summary, the introduction of a picolyl moiety into an azide probe leads to a substantial increase in the sensitivity of alkyne detection. This is of special value for the detection of low abundance targets or where significant increase in signal intensity is desired.
