Statement of Work Details

• Contribute to the development of stable cell lines for vaccine and therapeutic protein candidates, including monoclonal antibodies, recombinant proteins, and virus-like particles.

• Independently execute each step of the cell line development process: transfection, pool generation, single-cell cloning, clone expansion in static culture plates and shake flasks, fed-batch analysis, and clone stability studies.

• Participate in cell line development platform design, optimization, and cycle-time reduction studies, including methods for clone selection, expansion, ranking, and characterization.

• Generate stable pools and perform transient protein production to supply reagent-grade material.

• Maintain, support, and track maintenance for core laboratory equipment, including the ViCell BLU cell counters used on all cell line development projects to count cells during passaging and fed-batch production.

• Support the planning and execution of research experiments within the laboratory’s overall research program.

• Prepare plasmid DNA using standard molecular cloning techniques, including polymerase chain reaction (PCR), restriction digest, and bacterial culture.

• Use automated platforms for clone selection and screening.

• Support laboratory staff on research projects and techniques.

• Perform small-scale process development studies using various culture vessels, including tissue culture plates, shake flasks, and small-scale bioreactors.

• Maintain inventory of all supplies for the cell counters and request supplies as needed.

• Train team members on proper cell counter usage, reagent pack replacement and disposal, and data retrieval.

• Respond the same day to team member requests for troubleshooting support.

• Perform monthly quality control (QC) and weekly maintenance on the cell counters.

• Arrange service visits as needed and work with the vendor to ensure consistent performance of the instruments (currently five in the labs).

• Maintain a system of routine data backup.

• Assist in maintaining adequate space and facilities for ongoing and projected research studies.

• Write and review standard operating procedures (SOPs) for cell line development processes and instrumentation.

• Evaluate, analyze, and interpret research data, and communicate results and methods in reports, presentations, and manuscripts.

• Independently complete experiments and analyze data.

• Write and review technical reports documenting process development studies and stable cell line generation work.

• Maintain complete documentation records, including a detailed and up-to-date laboratory notebook, to support regulatory filings.

• Contribute results and studies for publication in peer-reviewed journals.

• Coordinate with junior staff to modify research protocols.

• Work with team members to generate experimental plans for process development studies.

• Present research at local and/or national scientific meetings and symposia, including in poster form.

• Provide interpretation of results, guidance, and scientific support to the management team.

• Coordinate cell line development projects with the project lead and Federal Task Leader.

• Plan experiments to fit within required timelines.

• Communicate any issues or delays promptly and help identify solutions.
