Polyclonal vs. monoclonal ADA — which do I need?

Polyclonal ADA mimics patient immune responses and is used as a positive control in immunogenicity screening/confirmation assays. Monoclonal anti-idiotype pairs are used as capture/detection reagents in sandwich ELISA for PK drug quantification. Check each product page for recommended applications.
