Species Cross Reactivity – Determined by Immunodiffusion

Each antibody listed has been tested for reactivity to the plasma of a variety of species. The double immunodiffusion (DID) technique used tests the ability of an antibody to precipitate an antigen in an agarose gel. The DID technique has limitations and a negative result should not necessarily be interpreted as non-recognition of an antigen. A number of antibodies may react with fewer recognition sites on the antigen of another species and be unable to form an insoluble immune complex (this is observed with many monoclonal antibodies). An antibody may demonstrate a greater spectrum of cross reactivity in applications such as immunoblotting and immunohistochemistry where antigen precipitation is not required. Below are examples of typical results seen in historical lots. See product insert for lot specific testing results.
