Anti-idiotypic binders validated in regulatory bioanalysis assay by Covance

Affinity_and_specificity_cropped-1

Antibodies have long represented the ‘gold standard’ for regulatory bioanalysis of therapeutic proteins. Yet, they are associated with a number of limitations, including development time, manufacturing complexity and lack of batch reproducibility. 

Our new application note details Covance’s validation to regulatory standards of an anti-idiotypic Affimer binder to Trastuzumab as part of a bioanalytical assay. Here Covance demonstrated the validity of Affimer binders as alternative or complimentary reagents to traditional antibodies within regulated PK assays, showing:

  • Accurate and sensitive quantification of the target therapeutic within disease state matrix
  • Improved dynamic range compared to current antibody-based assays
  • Excellent lot-to-lot reproducibility, reducing assay standardisation
  • Full development of the Affimer binder within 3 months
