항체-약물 접합체 (ADC)
Simplify antibody drug conjugate analysis characterization and drug-antibody ratio calculations
An antibody drug conjugate (ADC) is a protein — typically a monoclonal antibody (mAb) — covalently bound (conjugated) to a small-molecule drug using an ADC linker. Combining the targeting capabilities of a mAb with a potent cancer-killing drug allows sensitive discrimination between healthy and diseased cells. Development of these biotherapeutics is more difficult than development of mAbs alone due to the potency of the conjugated drug.
Our powerful technologies, including specific UHPLC systems, mass spectrometry, and LC columns designed for detailed ADC characterization, make separation and characterization of these novel molecules easier.

Hydrophobic interaction chromatography for determining drug load distribution
Separate mAbs and ADCs using Thermo Scientific MAbPac HIC-Butyl HPLC columns. Based on hydrophilic, nonporous, 5μm polymer particles. The latter functionalized with butyl groups. Hydrophilic resin provides excellent biocompatibility and low carryover, while the optimal density of the butyl groups provides high-resolution separation. The MAbPac HIC-Butyl column is one of our first HPLC columns designed and engineered specifically with antibody drug conjugates in mind.
Alternatively, use Thermo Scientific MAbPac SEC-1 Size Exclusion Columns for high-resolution separation of mAb monomers, aggregates and Fab and Fc fragments resulting from proteolysis. These size-exclusion chromatography (SEC) columns provide superior performance, even under non-denaturing conditions, and in high- and low-salt mobile phases and volatile eluents. Perfect for ADCs.
