The Immunology & 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 anti0drug antibodies (ADA) and neutralizing antibodies (Nab). Other assay types 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.
