Analytical Method Development

DAR and drug load distribution are critical quality attributes for ADCs. We offer comprehensive, high-quality assessment of DAR and drug load distribution tailored to meet our client’s specific needs. Our suite of analytical methods including UV-Vis spectroscopy, Hydrophobic interaction chromatography (HIC), RP-HPLC, and liquid chromatography coupled with electrospray ionization mass spectrometry (LC-ESI-MS). These methods enable us to accurately determine DAR and drug load distribution, meeting stringent quality standards.

Additionally, we provide advanced solutions for evaluating antigen-binding properties and activity using SPR, BLI, or ELISA platforms.
