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.

    MTT Formazan
    		99.67%
    MTT Formazan is a purple water-insoluble product formed by the reduction of yellow soluble MTT by succinate dehydrogenase in the mitochondria of viable cells. The amount of MTT Formazan produced is proportional to cellular metabolic activity, and it can serve as an indicator for evaluating cell viability and proliferation. MTT Formazan exhibits solvent-dependent solubility properties, and its absorbance value can be measured by spectrophotometry to reflect cellular status. MTT Formazan also supports the assessment of cell viability in bacterial MTT assays. MTT Formazan can be used in photoacoustic microscopy to enhance the imaging effect of viable cells, especially in applications in the fields of three-dimensional cell culture and tissue engineering.
