Job Description

Our Client is looking for an experienced protein biochemist to join the company’s drug discovery efforts. S/he is expected to play a central role in efforts to identify and progress lead LYTAC programs through their work in bioconjugation. A successful candidate has a solid base in amino acid chemistry and working with recombinant proteins and antibodies. This includes protein purification and the synthesis and analysis of antibody-drug conjugates (ADCs). A broad scientific background with a recent emphasis on ADCs may be ideal as occasional forays outside the central role of bioconjugation are likely.


  • Conduct antibody conjugation reactions at small and large scale using commonly employed lysine and cysteine chemistry.
  • Optimize synthetic procedures and purification protocols for ADCs to maximize both the efficiency of conjugation and product stability.
  • Analytical characterization of ADCs and naked Mabs by LC-MS, SEC, IEC, and SDS-PAGE.
  • Assess binding characteristics ADCs in vitro.Occasional assessment of ADC bioactivity in cell-based assays.
  • Maintain an accurate database of ADCs.
  • Analyze, document, and report data.
  • Present unbiased results in regular group meetings


  • BS/MS in biochemistry or related field with a minimum of 2 years experience in the chemical conjugation of proteins and 7+ years total lab experience.
  • Experience with intact mass analysis of proteins and/or ADCs by LC-MS.Use of AKTA systems for protein purification via SEC, IEC, and affinity chromatography.
  • Experience with analytical SEC and reverse phase chromatography (HPLC).
  • Sound understanding of biological buffers and the effect of pH on amino acid chemical reactivity.
  • Sound understanding of protein stability and the ability to determine when a reagent (protein or ADC) is compromised.
  • Experience with endotoxin testing and prevention of endotoxin contamination of equipment and reagents.
  • Basic tissue culture skills and understanding of data generated in cell-based functional assays.
  • Experience with electronic notebooks.
