Enzyme-Linked Immunosorbent Assay for T-Cell Dependent Immunogenicity Assessment of Therapeutic Peptides.

Enzyme-Linked Immunosorbent Assay for T-Cell Dependent Immunogenicity Assessment of Therapeutic Peptides. Methods Mol Biol. 2019;1930:129-138 Authors: Chalasani MLS, Lakshminarayanan R, Verma NK Abstract Immunogenicity assessment of therapeutic peptides, proteins, oligonucleotides, and hybrid molecules, such as nucleopeptides, is a major aspect in understanding their safety and efficacy. Both T-cell independent and dependent immune reactions contribute to an immunogenic response against antigen, including secretion of cytokines and production of an antigen-specific antibody. Various assays exist for detecting and quantifying such immunogenic responses by human T-cells ex vivo or in mouse serum, which primarily include enzyme-linked immunosorbent assay (ELISA, direct and indirect), flow-cytometry and surface plasmon resonance (SPR). ELISA is a popular choice due to its robustness, reliability, sensitivity, ease of automation, and the requirement of simple equipment commonly available in most molecular biology and biochemistry laboratories. The chapter describes the detailed protocol of cytokine analysis by an ELISA method and highlights few crucial steps to be considered while performing the assay for successful immunogenicity studies.
