Conjugated primary antibodies

Primary conjugated antibodies allow for direct detection of a target antigen without a secondary antibody, which can bind non-specifically. Using directly labeled primary antibodies can save you a significant amount of time and simplify your experimental protocol.

Fluorescent conjugated primary antibodies are ideal tools for multicolor experiments. Our range of recombinant primary conjugated antibodies to Alexa Fluor^® Dyes, FITC, PE, PerCP, APC, and tandem dyes is extensively validated in flow cytometry and imaging applications, including IHC and ICC/IF. Use our fluorochrome chart to choose the right dyes to build your panel.

Conjugating antibodies to fluorophores is quick and easy with our range of Lightning-Link^® conjugation kits for over 45 labels, including fluorescent proteins, tandem dyes, enzymes, oligonucleotides, and gold nanoparticles. If you cannot find the right combination of antibody and label in our catalog, choose a conjugation-ready carrier-free format of your clone of interest, and conjugate your antibody in three simple steps.
