Fluorescent Dyes Labeling Services

Creative Biolabs offers a variety of fluorescent dye labeling services for worldwide customers for both research and commercial use. Based on years of conjugation experience, our custom fluorescent antibody and protein labeling service includes experimental design and development of protocols for the preparation of conjugates to be used in various detection systems.

Introduction of Fluorescent Dyes Labeling

Fluorescent dye labeling, often known as fluorescent tag or fluorescent probe, is the use of chemically bound molecules to detect biomolecules such as proteins, antibodies, amino acids, or nucleic acids. Most importantly, the assays can be performed in real-time, in solution, with high-time resolution and sensitivity down to single molecules. Moreover, the advantages of using a fluorescently labeled antibody include harmlessness to target molecule folding and function, brighter signal, multiplexing capabilities, and ease of use (many are available pre-conjugated to many different colors of dyes).

Applications of Fluorescent Dyes Labeling

• Bioimaging
  Fluorescent dyes are extensively used for fluorescent labeling of various biomolecules, such as peptides, proteins, antibodies, and nucleic acids, to visualize cellular structures and processes. They make it possible for scientists to investigate cellular mechanisms, protein mobility and localization within cells, protein-protein interactions, gene expression, and the localization of specific molecules within cells.
• Flow cytometry
  Fluorescent dyes are used in flow cytometry to label and analyze cells based on their physical and chemical properties. Different dyes can be used simultaneously to identify and quantify specific cell populations, measure cell viability, and assess cell cycle progression. This strategy is frequently used in medical laboratories to diagnose disorders and assess the efficacy of therapies.
• Immunohistochemistry
  Fluorescent dyes are employed in immunohistochemistry techniques to label specific antigens within tissue sections. This allows for the visualization and localization of proteins or other biomarkers of interest within the tissue, aiding in disease diagnosis, understanding cellular function, and studying tissue development.
• Molecular biology research
  Fluorescent dyes are widely used in molecular biology research to label DNA, RNA, and other molecules. They can be used for techniques such as fluorescence in situ hybridization (FISH), polymerase chain reaction (PCR), and DNA sequencing. These techniques enable the detection and analysis of specific DNA or RNA sequences, gene expression profiling, and genetic mapping.
• Drug discovery and development
  Fluorescent dyes are utilized in drug discovery and development processes to study drug-target interactions, evaluate drug efficacy, and assess cellular uptake and distribution of potential therapeutics. They play a vital role in high-throughput screening assays and drug delivery system development.
