Conjugation is the process of forming a stable hybrid using molecules such as a protein, antibody, peptide, or small molecule. These molecules can be conjugated with various modalities such as haptens, enzymes, carrier proteins, polymers, particle conjugates, isotopes, fluorescent labels, etc.
Biological research requires molecular labels covalently attached to a protein of interest to facilitate the detection or purification of the labeled protein and/or its binding partners. Currently, various labeling approaches (fluorescence labeling and isotopic labeling) are used by industrial entities for protein profiling to quantify compounds and to monitor and study biological processes.
The pharmaceutical industry widely uses conjugation and Labeling Services in several application areas, such as the development of conjugated drugs, drug delivery systems, disease diagnosis, the invention of diagnostic tools, and high-throughput screening. Due to the high demand for conjugated biomolecules in the field of research and development, multiple players worldwide are actively engaged in providing efficient antibody conjugation services.
