WebELISA (enzyme-linked immunosorbent assay) is a plate-based assay technique designed for detecting and quantifying soluble substances such as peptides, proteins, antibodies, and hormones. Other names, such as enzyme immunoassay (EIA), are also used to describe the same technology. In immunology, an antigen (Ag) is any molecule, molecular structure, foreign particulate matter, or pollen grain that can bind to a specific antibody or T-cell receptor. The presence of antigens in the body may trigger an immune response. Antigens can be proteins, peptides (amino acid chains), polysaccharides (chains of simple sugars), lipids, or nucleic acids.

WebIntroduction. Antibody-antigen complex formation is defined as a spontaneous chemical reaction. For a reaction to occur spontaneously (no additional energy input required for reaction to occur), the sum of all chemical interactions must result in a negative change in free energy (-ΔG). WebAntibody modification (including antibody fragments) has maintained a healthy research focus for several decades now, largely due to the rapid development of the antibody–drug conjugate field. This has resulted in a rich toolbox of chemical reactions which enable facile, site-selective modification whilst avoiding negative effects on the function of the protein.
