Based on the comprehensive and high-efficient platform, Creative Biolabs is professional in discovery potential immunogenicity of biological drugs. Our years of experience, vast expertise and advanced platform in immunogenicity evaluation make us confident in offering the best quality ADA screening assays for global customers.

Introduction of ADA Screening Assays

In accordance with regulatory guideline requirements, bioanalytical testing for ADAs should be conducted in a tiered testing format. Among these tiered testing methods, screening assays are the first step in any immunogenicity evaluation. The aim of the assays is to detect antibodies in patient samples which are unique to each patient and differ in characteristics (isotype and affinities etc.) between patients and also within the same patient following multiple administrations of the product. This is because different subjects may produce either one or more antibodies to a drug, each having different binding affinities and/or specificities, therefore making it impossible to compare the response to a reference standard and thus provide an accurate quantitative value.

ADA Screening Assays Provided by Creative Biolabs

With years of experience, Creative Biolabs is able to provide multiple ADA screening assay formats with high reliability and sensitivity for the quasi-quantitative or qualitative of potential antibodies. Generally, assay formats vary between different proteins and likely to depend on the therapeutic protein class. Our professional scientists will help you select an appropriate assay format to detect antibodies with desired specificities (IgM, IgG subclasses etc.) against test drugs. The common methods we offer for ADA screening are listed as follow:

  • Direct/Indirect ELISA
  • Bridging ELISA
  • Electrochemiluminescence (ECL)
  • Radioimmunoprecipitation assay (RIPA)
  • Surface plasmon resonance (SPR)
