Light-up your research with our fluorescent and enzyme primary antibody conjugates!

Conjugated primary antibodies are an excellent alternative to using a secondary antibody for detection of your target protein. A conjugated primary antibody is created by pre-attaching (conjugating) a tag of your choice (fluorophore, enzyme, or protein), to a primary antibody, allowing for visualization of your target protein without the need to purchase a costly secondary antibody.

Conjugated primary antibodies can easily replace your previous primary/secondary antibody pairs in the following applications*:

  • Western blot (WB), Immunohistochemistry (IHC), Immunofluorescence (IF), Immunocytochemistry (ICC), Flow Cytometry (FCM), Fluorescence-activated cell sorting (FACS), Enzyme-Linked Immunosorbent Assay (ELISA), Förster Resonance Energy Transfer (FRET)
