Job Description


The Bioconjugation Group in Abzena Cambridge (UK) provides conjugation solutions to support partner antibody drug conjugate (ADC), PEGylation and other conjugate development programs. Using established conjugation chemistries and its proprietary conjugation platform ThioBridge® with access to a wide range of cargo’s, the Bioconjugation Group designs, synthesises and produces ADC candidates that are evaluated with support from the Design and Developability Groups for lead candidate selection.

Our team of highly skilled and passionate bioconjugation chemists has access to state-of-the-art laboratories on the Babraham Research Campus in Cambridge, equipped with the latest high containment capabilities and a range of automated LC systems to develop appropriate purification approaches for the production of ADCs and bioconjugates. The Bioconjugation Group works closely with the Analytical Group with access to instrumentation such as UPLC chromatography, microfluidics capillary electrophoresis and high resolution Q-TOF, high sensitivity TOF and Orbitrap mass spectrometers, as well as light scattering instrumentation to support analytical characterisation of bioconjugates.

An exciting opportunity has opened up to join the group at Scientist or Senior Scientist level for a bioconjugation/protein chemist who will help us deliver for high-paced client projects. The ideal candidate will have a background in protein biochemistry or chemistry with strong laboratory skills and previous industrial experience.
