Currently, the demand for various bioconjugates in the pharmaceutical industry is high, particularly for antibody drug conjugates (ADCs). As a CRO providing comprehensive bioconjugation services, BOC Sciences has developed a bioconjugation platform for Good Laboratory Practice (GLP) studies and the use of validated systems and Good Manufacturing Practices (GMP) for the production of bioconjugates.
Introduction
Bioconjugation is a chemical process that links two molecules, at least one of which is a biomolecule such as a carbohydrate, nucleic acid, or protein. Recent advances in biochemistry have enabled the development of more efficient bioconjugation reactions, including bioorthogonal reactions, ketone and aldehyde modification reactions, N- and C-terminal modification, and labeling-site selectivity. These bioconjugates can be used for a variety of purposes, including cellular tracking, imaging biomarkers, and targeted drug delivery.
The manufacture of bioconjugates is a complex process that must comply with cGMP (Current Good Manufacturing Practice) to ensure the safety and consistency of the bioconjugates. Starting with the parent molecule, through the generation of the conjugates and ending with the purification of the bioconjugates, cGMP is used throughout. cGMP bioconjugate manufacturing involves the use of specialized equipment and materials to ensure the high quality and purity of the final product.
BOC Sciences provides comprehensive conjugation services for research and development of bioconjugates. Our conjugation purification lines can perform hundreds of liters of conjugation reactions, providing the flexibility to meet the production needs of our global partners.
