AbTis Co., Ltd. (앱티스) is a South Korean biotechnology company founded in 2016 and headquartered in Yongin-si, Gyeonggi-do, inside the Dong-A Socio Holdings R&D Center. It develops AbClick, a third-generation site-selective antibody conjugation platform that attaches payloads to the Fc Lys248 residue of native IgG antibodies with no enzyme and no Fc engineering, giving a controlled drug-to-antibody ratio and batch-to-batch consistency across ADC, DAC, AOC, ARC, ISAC and dual-payload designs. AbTis licenses the platform, runs collaborative research and fee-for-service ADC development, and advances its own pipeline led by AT-211, a Claudin 18.2-targeting MMAE ADC. Acquired by Dong-A ST in 2023, it now operates as that company's ADC-specialised subsidiary. Its product is licensed chemistry and drug intellectual property, not software: it runs no developer program, public API, SDK or machine-readable contract.
