Secondary Antibodies

Affinity-purified secondary antibodies for accurate signal detection across every assay format

Secondary antibodies carry the detection label into the assay when your primary antibody is unconjugated. Most are affinity-purified, giving low background and high sensitivity across western blot, ELISA, IHC, and immunofluorescence formats. Label options include HRP for chemiluminescent western blot, biotin for amplified detection systems, and fluorophores for immunofluorescence, flow cytometry, and multiplexed imaging, with species-specific and isotype-specific formats available to reduce cross-reactivity in multi-labelling experiments. Pre-matched antibody bundles combine validated primary and secondary pairs for defined target panels such as exosome marker profiling, removing the validation step when you already know the targets you need.
