MINI CASE STUDIES
The LC-HRMS analysis provided detailed insights into the metabolites formed from the uncleavable ADC. The identification of various metabolic forms of the payload, reveals the complexity of ADC metabolism and highlights the importance of thorough metabolic characterization in ADC development. This knowledge aids in the optimization of ADC design to improve stability, efficacy, and safety. Contact us for more detailed case study data.
For DS-8201, a HER2-targeting ADC, this evaluation helps in understanding how the Drug-to-Antibody Ratio (DAR) changes over time and how stable the payload and antibody components are in plasma. The findings highlight the importance of early stability assessments in ADC development, particularly for optimizing the linker and overall molecular stability. By leveraging our comprehensive stability study platform, including free small molecule toxins, conjugated small molecule toxins, conjugated antibodies, total antibodies, and DAR values, we can guide the optimization of ADC molecules to improve their therapeutic potential.

We have developed a robust LC-MS-based quantitative method for analyzing DS-8201 (an Antibody-Drug Conjugate) and Trastuzumab (Naked antibody). Our LC-MS method provides results consistent with those obtained using ELISA, effectively meeting the diverse needs for biologics quantification in various scenarios. This comparison demonstrates the reliability and accuracy of our LC-MS method, making it a valuable tool for comprehensive ADC and antibody analysis. Contact us for more detailed case study data.
