Product overview

What are conjugated primary antibodies?

St John's Laboratory lists thousands of conjugated primary antibodies, covering a wide range of fluorescent, enzymatic and affinity tag labels.

  • Direct detection, no secondary needed Because the label is already attached to the primary antibody, conjugated antibodies remove the need for a separate secondary antibody step in an assay.
  • Suited to multiplexing 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.
  • Monoclonal and polyclonal options St John's Laboratory offers 9,733 monoclonal and 2,949 polyclonal conjugated antibodies, giving a choice between single-epitope consistency and broader signal detection.
