The Immunology and Immunochemistry disciplines support large molecule drug development using ligand binding assays (LBA), such as enzyme-linked immunosorbent assay (ELISA), to measure large molecules and their immune responses. The main types of assays include Pharmacokinetic (PK) assays to measure drug and Immunogenicity assay to measure anti-drug antibodies (ADA) and neutralizing antibodies (NAb). Other assay types also performed are branched DNA (bDNA) and cell-based assays. An array of platforms are used to support these assays that include spectrophotometer, Meso Scale Discovery (MSD), Luminex and Gyrolab. Utilizing these platforms/assays, the teams are responsible for the method development, validation and routine sample analysis in both the regulated and non-regulated space of non-clinical and clinical studies.
