## TL;DR

Abzena is a bioconjugation and biologics CDMO with the ThioBridge site-specific linker technology.

## Summary

Abzena, based in Cambridge in the United Kingdom, is a bioconjugation and biologics CDMO that owns the ThioBridge site-specific linker technology. Its services span antibody engineering, immunogenicity assessment, ADC conjugation in San Diego and biologics manufacturing in Bristol, Pennsylvania. OnCo links it to ADC bioconjugation manufacturing and to site-specific conjugation and linker chemistry. Whether a CDMO that also licenses its own linker can stay neutral between clients using competing chemistries is the fair question. The ADC manufacturing page carries the wider picture.
