Conjugated Primary Antibodies

Primary antibodies with the reporter label already attached

A conjugated antibody is attached to a substrate such as an enzyme, toxin or inorganic compound. These are high-performance monoclonal or polyclonal antibodies coupled to a colorimetric or fluorescent label for use as reporter molecules in primary or secondary antibody immunoassays.

Product overview

What are conjugated primary antibodies?

Because the label is already attached to the primary antibody, conjugated antibodies remove the need for a separate secondary antibody step in an assay. Different fluorescent conjugates can be combined in the same experiment, which makes conjugated antibodies a common choice for flow cytometry panels and multi-target imaging. Our range covers thousands of conjugated primary antibodies across fluorescent, enzymatic and affinity tag labels.

Category benefits

Why use conjugated primary antibodies?

✓ Direct detection, no secondary needed
The label is already attached to the primary antibody, which removes the need for a separate secondary antibody step in an assay.
✓ Suited to multiplexing
Different fluorescent conjugates can be combined in the same experiment, making these antibodies a common choice for flow cytometry panels and multi-target imaging.
✓ A choice of monoclonal or polyclonal formats
The range includes 9,733 monoclonal and 2,949 polyclonal conjugated antibodies, giving a choice between single-epitope consistency and broader signal detection.
