Select your secondary antibody

Using the knowledge from the “Experimental design – how-to reference guide” section and your desired application, follow the steps below to discover your ideal secondary antibody.


  1. Target species
  2. Host
  3. Class and chain (found in the specificity filter)
  4. Isotype
  5. Format
  6. Check before you select – does your antibody need to be cross-adsorbed?

Use the filters to systemically select your requirements and discover the best secondary antibody for your experiment, then download the results.

    Top tips

    • When using more than one secondary antibody ensure that they don’t cross react
    • When working with some immune tissues or cells that contain a lot of Fc receptors, it helps to choose a F(ab) or F(ab’)2 fragment to eliminate non-specific binding. Alternatively, block Fc receptors via an absorption step, using purified IgG from the host species of your secondary antibody or serum from target cells
