Bioanalytics

Bioanalytics

BOC Sciences bioanalysis service department has a professional scientific research team, the analysis laboratory is equipped with advanced instruments and equipment, and comprehensive information management is implemented. The experimental research meets the requirements of FDA/CFDAGLP standards. The service covers pharmacokinetics, pharmacodynamics, immunogenicity and bioequivalence, and provides customers with screening and development of Antibody-Drug Conjugates (ADCs) drugs, as well as preclinical and clinical research.

ADC has both the specificity of large-molecule drugs and the cytotoxicity of small-molecule drugs, and ADC need to bioquantitate their antibody and small-molecule drug components during the development process. ELISA and LC-MS/MS methods have become common bioanalytical techniques for ADC analysis. Traditionally, the in vivo quantitative analysis of biological macromolecules uses the ELISA method, and small molecule drugs use the LC-MS/MS method. In the process of ADC drug development, structural confirmation, characterization, and quality control are all important links, which must be as accurate, sensitive and selective as possible.
