Original text. Later amendments are not shown.

Several ELISA techniques using specific monoclonal antibodies have been developed, which are based on two formats: competitive or blocking ELISA and non-competitive ELISA.

The competitive or blocking ELISA is usually based on monoclonal antibodies. If the serum sample contains antibodies to classical virus, the binding of a selected peroxidase-conjugated monoclonal antibody to virus antigen will be inhibited resulting in a reduced signal.

In non-competitive ELISA the binding of serum antibodies to antigen is measured directly using peroxidase-conjugated anti-pig antibodies.
