Cell Based Potency Assay information

What are some common challenges faced when developing and validating cell based potency assays in a laboratory setting?

Developing and validating cell-based potency assays can be challenging due to the inherent biological variability of living cells, which can impact assay reproducibility and consistency. Additionally, optimizing assay conditions—such as cell passage number, incubation times, and reagent quality—requires careful attention to detail. Collaboration across multidisciplinary teams, including scientists, quality control, and regulatory affairs, is often necessary to ensure the assay meets rigorous industry and compliance standards. Successful candidates should be comfortable troubleshooting technical issues and adapting protocols to achieve reliable results.

What are the key skills and qualifications needed to thrive as a cell based potency assay scientist, and why are they important?

To excel as a Cell Based Potency Assay Scientist, you need a solid background in cellular biology, assay development, and quantitative analysis, usually supported by a degree in life sciences or a related field. Familiarity with laboratory instruments like flow cytometers, plate readers, and proficiency in data analysis software such as GraphPad Prism are typically required, along with knowledge of GMP/GLP standards. Attention to detail, strong problem-solving abilities, and effective communication skills are essential soft skills in this role. These competencies ensure accurate assay results, regulatory compliance, and clear collaboration with cross-functional teams in biopharmaceutical development.

What are cell based potency assays?

Cell based potency assays are laboratory tests that use living cells to measure the biological activity of a drug, vaccine, or biologic product. These assays help determine how effective a compound is in producing a desired cellular response, making them crucial for drug development and quality control. By closely mimicking the drug’s mechanism of action in the body, they provide more relevant information about efficacy and safety compared to non-cellular assays.

What is the difference between Cell Based Potency Assay vs Cell Culture Technician?

AspectCell Based Potency AssayCell Culture Technician
Primary ResponsibilitiesAssessing the biological activity of products using cell-based methodsMaintaining and preparing cell cultures for various experiments
Required SkillsKnowledge of assay development, data analysis, cell biology techniquesCell culture techniques, aseptic handling, media preparation
Work EnvironmentLaboratories focused on assay validation and quality controlCell culture labs, manufacturing, or research facilities
Common CertificationsBiotech or laboratory certifications, cell biology trainingCell culture training, laboratory safety certifications

While both roles involve working with cells, the Cell Based Potency Assay specialist focuses on developing and performing assays to measure product activity, whereas the Cell Culture Technician primarily prepares and maintains cell cultures. The assay role requires analytical skills and assay-specific knowledge, while the technician role emphasizes cell handling and maintenance skills.

Senior Scientist I, Functional Biocharacterization & Impurities

Location: Redmond, WA

About Us:

At Just-Evotec, we believe that curiosity is the spark that drives innovation and success. As a forward-thinking team, we thrive on challenging the status quo, learning from each other, and pushing the boundaries of what's possible. We're on a mission to create a place where curiosity isn't just encouraged, it's celebrated.

Are you someone who asks questions, seeks answers, and isn't afraid to go deeper?#BeCureious with us and see where your curiosity can take you!

The Role:

Just - Evotec Biologics is seeking a motivated and creative senior scientist who desires a significant opportunity to improve worldwide access to biotherapeutics. The candidate will join a fast-paced, collaborative, and multidisciplinary team to develop and execute methods for assessment of the function and potency of biotherapeutics. As a key member of the analytical development group, the successful candidate will have significant experience in cell-based assays in an array of formats and experience with method development and phase-appropriate validation. Previous experience in late phase biologics development and/or biosimilar development, participation in CMC teams, and experience authoring regulatory documents is highly desirable. Previous experience directly managing a diverse group of analytical scientists (potency/bioassay) is highly desirable. The ideal candidate has strong written and verbal communication skills, multitasks effectively, works well independently and in teams, and is excited about ways to improve technology. The candidate will also be involved in leading cross-functional initiatives and supervising direct reports.

Responsibilities:

  • Serve as a subject matter expert in development of a wide range of formats of cell based assays for early and late phase biologics programs
  • Lead a team of scientists to implement method development and phase-appropriate validation activities for cell based assays in a wide range of formats
  • Supervise and develop the careers for direct reports; mentor and train junior staff
  • Transfer methods to Just - Evotec's Quality Control laboratory
  • Technical document authoring
  • Participate in process development teams, potentially serving as potency lead and as analytical team lead
  • Execute comparability and biosimilarity assessments
  • Technology development to improve throughput, efficiency, and onboard new technologies
  • Author and contribute to documents to support regulatory filings (including IND, INDa, BLA, IMPD)
  • Present data to a wide range of audiences, including internal technical development teams, clients, industry conferences, and peer-reviewed journals
  • Lead cross-functional teams and initiatives


Required Qualifications:

  • PhD with 3+ years relevant industry experience, MS with 5+ years' industry experience, or BS with 10+ years' experience, with degrees in Biochemistry, Molecular and Cellular Biology, Chemical Engineering, Bioengineering, Chemistry or related field
  • Understanding of ICH/USP guidelines on analytical and potency assay development and validation
  • Experience in the development and phase-appropriate validation of potency and methods
  • Experience managing and mentoring direct reports
  • Strong technical understanding of link between Mechanism of Action and analytical method development. Understand the effects of impurities on biological manufacturing processes
  • Experience in areas of technology development pertinent to potency assay development, including but not limited to, FcgR effector function assay development, large-scale cell banking, and image and flow cytometry
  • Strong oral and written communication skills
  • Desire to work in a fast, collaborative, and team-oriented environment
