Creative Biolabs offers a variety of fluorescent dyes 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 include experimental design, development of protocols for the preparation of conjugates to be used in various detection systems.

Introduction of Fluorescent Dyes Labeling

Fluorescent dyes can be conjugated directly to the primary or secondary antibody. In recent years, fluorescence-based assays have become crucial experimental tools for the measurement of protein interactions, enzymatic activity, conformation changes, and localization of proteins. Many biological experiments, such as fluorescent cell imaging, western blotting, and immunohistochemistry, have adopted fluorescent-dye conjugated antibodies as an important tool for identifying proteins. Most important, 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 brighter signal, multiplexing capabilities, and ease of use (many are available pre-conjugated to many different colors of dyes).

Fluorescent Dyes Labeling Services Provided by Creative Biolabs

With extensive experience and professional scientists, Creative Biolabs has the ability to conjugate your antibody or protein to numerous fluorescent dyes. In order to verify that the observed fluorescence is a result of staining rather than an unspecific artifact, our skilled staffs will work closely with you to help select the most suited dye and labeling site according to your specific requirements. Starting from customer supplied antibodies or Creative Biolabs generated custom antibodies, we deliver fluorescent dyes labeled antibodies in a relatively short duration. Furthermore, each labeled service is meticulously monitored by our quality assurance center. The fluorescent dyes we can offer are shown as below, which including but not limited to:
