Abstract
Described herein are protein-payload conjugates and compositions thereof that are useful, for example, for target-specific delivery of therapeutic and/or imaging agent moieties. In certain embodiments, provided are specific and efficient methods for producing protein-payload constructs (e.g., antibody-drug conjugates) utilizing a combination of transglutaminase and Diels-Alder techniques. Antibody-drug conjugates and compositions which comprise glutaminyl-modified antibodies, Diels-Alder adducts, and reactive payloads and are provided.
