FIG. 2.
Schematic representation of the SNAP procedure. The primers used for the PCR step are indicated (●, DIG or FITC label), as is the SNAP oligonucleotide (■, biotin labeled) used for capture of the specific product onto the streptavidin (S)-coated ELISA plate. Final detection is in a standard ELISA format using peroxidase-labeled (POD) antibody.
