Research Engineer Protein Purification - Affibody - Avslutad

The Research Engineer Protein Purification will focus on purification of Affibody® molecules, in Affibody’s research pipeline, as well as in downstream process development after CD selection. He or she will plan and execute experiments, perform in-process analyses, analyze data, and report results to meet specified timelines and objectives.

The Research Engineer Protein Purification will be part of the Protein Chemistry team and will be directed by the objectives and demands of the research and development projects. The Protein Chemistry team currently has six members, and is one of four research groups at Affibody, each led by a Principal Scientist with profound expertise in the respective discipline.

Key Responsibility Areas

  • Plan and execute experiments, analyze data and report results to meet specified timelines and objectives
  • Plan and perform purification of Affibody constructs from E. coli cultivations (e.g. Affinity purification, RPC purification, IEX purification and buffer exchange).
  • Plan and perform in-process analyses and analysis of final purified product (e.g. SDS-PAGE, RP-HPLC, LC/MS, SEC, Circular Dichroism measurement, Endotoxin analysis and A280 measurement).
  • In cooperation with other group members, plan and execute stability studies before Candidate Drug (CD) selection
  • In cooperation with other group members, plan and execute downstream process development of selected CD.  including technology transfer to CMO for out-sourced GMP production
  • Responsible and accountable for generated results and given timelines
  • Responsible for documentation and reporting findings within given timelines
