This Expert Insights eBook gives scientists and development teams a chemistry-to-characterization view of antibody-drug conjugates (ADCs), from bioconjugation and linker design through the LC–MS methods used to quantify each ADC species.
What you will learn about:
- How click-type and site-selective bioconjugation reactions modify antibodies at lysine, cysteine, and tyrosine residues
- Why linker chemistry and conjugation strategy now drive an ADC’s therapeutic index, homogeneity, and DAR control
- What discontinued ADCs reveal about linker stability, payload selection, and off-target toxicity
- How advanced cleavable linkers and hydrophilic spacers improve plasma stability and payload release
- Which LC–MS strategies quantify intact ADC, total antibody, payload, and catabolite species, and where current methods fall short

More Information
Antibody-drug conjugates hold a central place in targeted cancer therapy, but their performance rests on more than antigen recognition. Payload conjugation strategy, linker stability in circulation, drug release efficiency, and drug-to-antibody ratio (DAR) all shape efficacy and toxicity. This eBook brings together three complementary perspectives on ADC chemistry: the bioconjugation reactions behind modern protein modification, innovation in linker and site-specific conjugation, and the LC–MS methods that characterize each molecular species during development.
