Abstract: Antibody drug conjugates (ADCs) as novel protein drug modalities have made considerable progress through the last decades with ten ADCs approved by FDA to date. The structural complexity of ADCs, as well as formulation in MS incompatible buffers, imposes challenges on analytical method development, especially for in-vivo biotransformation samples, which typically require extensive sample preparation and high sensitivity detection. Here, we take advantage of a microfluidic channel-based platform, SampleStream (Integrated Protein Technologies, Fig 1), that uses a molecular weight cutoff (MWCO) membrane for automated buffer exchange and sample enrichment. The platform could be easily coupled with an ultra-high resolution QTOF instrument for the MS analysis and DAR measurement of intact ADCs under native and denaturing conditions.Summary: Here, we take advantage of a microfluidic channel-based platform, SampleStream (Integrated Protein Technologies, Fig 1), that uses a molecular weight cutoff (MWCO) membrane for automated buffer exchange and sample enrichment.
