PK and ADA Assay Development Services

Applying anti-ID antibodies as critical reagent in IND filing and clinical trials

Pharmacokinetics and Immunogenicity ELISA Kit Development Service

GenScript ProBio guarantees to deliver high-quality PK and ADA assay for measurement of free drugs, binding drugs, total drugs and anti-drug antibody in both discovery and clinical stages. We offer a complete PK kit for the of the drug discovery and development process.

Quality Consistency of Critical Reagents

For ligand binding assays (LBA), the critical reagents are the reagents/molecules (usually produced by biological processes) involved in binding and staining reactions, which can affect the assay results. Therefore, these reagents can affect the validity of the LBA assay.

As a critical reagent used in IND filing and clinical trials, the batch variation of anti-idiotype antibodies significantly affects the performance of following PK/ADA assay. Particularly in long-term clinical use, it is critical to ensure batch-to-batch consistency.

GenScript ProBio provides the best practice and compliance in anti-ID antibody manufacturing and PK/ADA kit development.
