Fluorescent reagents of many types continue to be developed to stain or chemically label proteins, nucleic acids and other biomolecules. When specific antibodies or other purified biomolecules are chemically labeled with fluorescent dyes, they become fluorescent probes for detection of target antigens or interaction partners in applications such as cell imaging, high-content analysis, flow cytometry, western blotting and ELISA.
Our broad portfolio of fluorescent reagents includes Invitrogen Alexa Fluor Dyes, as well as various traditional and specialty fluors associated with our Invitrogen and Thermo Scientific Pierce product lines.
Whether your needs are for already-labeled, ready-to-use fluorescent secondary antibodies or for specific reagents and kits to chemically label and prepare your own probes, we almost certainly offer the product you are looking for.
Featured fluorescent protein labeling reagent categories
Microscale Protein Labeling Kits conveniently label small amounts (20–100 μg) of purified protein or antibodies with a bright, photostable Alexa Fluor dye or biotin-XX.
Fluorescent-dye conjugated secondary antibodies provide a much needed tool for identifying proteins in many applications including fluorescent cell imaging, western blotting, immunohistochemistry and more.
Streptavidin-based amplification techniques are widely used in flow cytometry, fluorescent imaging, western blotting, and microplate-based detection for increased signal output and greater sensitivity.
