Specific for either the Igκ or Igλ light chains, or the heavy chain of ferret IgG (Igγ). In isolation, or in combination, these antibodies enable detection of ferret Ig using Western blot, ELISA, flow cytometry, ELISPOT and FluoroSpot techniques. Moreover, these antibodies can also be used for purification of ferret Ig via affinity chromatography.
