FAQs About Fluorescent Reagents
What are fluorescent probes?
Fluorescent probes are molecular tools capable of specifically recognizing target molecules and emitting fluorescence signals. They are widely used in biological imaging, molecular detection, and analytical fields. Typically composed of a fluorescent group and a recognition moiety, they can bind to specific targets such as DNA, RNA, proteins, or ions. Upon binding, their fluorescence properties change, enabling visual tracking and quantitative analysis of the target. Fluorescent probes are crucial in areas like cell biology, disease diagnostics, and drug screening.
How do fluorescent probes work?
The working principle of fluorescent probes lies in their selective binding to target molecules and corresponding fluorescence signal response. When the probe binds to the target molecule, changes such as fluorescence enhancement, quenching, or wavelength shift occur. These changes are captured by detection instruments and used for qualitative or quantitative target analysis. Fluorescent probes emit light of specific wavelengths through their fluorophores, enabling real-time monitoring of spatial positioning or dynamic changes of biomolecules such as cells, proteins, and nucleic acids. Their high sensitivity and selectivity make them essential tools in life science research and clinical diagnostics.
What are fluorescent dyes?
Fluorescent dyes are organic or inorganic compounds capable of emitting fluorescence upon excitation by light at specific wavelengths. They are commonly used to label and detect specific structures or molecules in biological samples. These dyes are widely applied in techniques such as cell imaging, immunoassays, DNA sequencing, and flow cytometry. Depending on their emission wavelengths, fluorescent dyes can cover a wide range from UV to near-infrared, and offer advantages such as high brightness, good photostability, and structural diversity. They provide reliable technical support for multiplex detection and high-resolution imaging.
How do fluorescent dyes work?
Fluorescent dyes absorb excitation light of a specific wavelength, transitioning from the ground state to an excited state. When returning to the ground state, they release energy as fluorescence at a characteristic wavelength. This emission can be captured by fluorescence microscopes, flow cytometers, or spectrometers, enabling visualization and quantitative analysis of samples. Different dyes have distinct excitation/emission characteristics and can be selected according to experimental needs. Dyes can be covalently or non-covalently labeled to nucleic acids, proteins, or organelles, supporting a wide range of bioanalytical and imaging studies.
