Cell Based Potency Assay information

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 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 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.

Job description


About Allogene:

Allogene Therapeutics, with headquarters in South San Francisco, is a clinical-stage biotechnology company pioneering the development of allogeneic chimeric antigen receptor T cell (AlloCAR T) products for cancer and autoimmune disease. Led by a management team with significant experience in cell therapy, Allogene is developing a pipeline of “off-the-shelf” CAR T cell product candidates with the goal of delivering readily available cell therapy on-demand, more reliably, and at greater scale to more patients.

About the role:

Allogene is seeking a highly determined, results-oriented, self-starter who demonstrates personal accountability for outcomes and is motivated by increasing levels of responsibility, to join a dynamic team responsible for successful development and characterization of clinical-scale manufacturing of Allogeneic Chimeric Antigen Receptor T-cell therapies (Allo CAR T™). The successful candidate will help to support appropriate analytical methods for the characterization, release and stability testing of CAR-T products. This position will also contribute to the development of novel technologies and approaches to meet future CART analytical needs and work in close collaboration with key stakeholders, including the CART Research and Process Development groups.

Responsibilities include, but are not limited to:

  • Actively contribute to successful and efficient execution of robust, state-of-the-art multicolor flow cytometry methods, cell-based potency assays and molecular assays for the characterization of CAR T manufacturing processes and products
  • Provide analytical support for the development and execution of Process Characterization and BLA-enabling activities, including qualification of in-process and release methods and tech transfer internally and externally in support of GMP manufacturing and release of clinical material.
  • Contribute to project technical teams to ensure effective communication at all levels. Collaborate effectively to ensure productive interactions with all stakeholder groups.
  • Demonstrate strong accountability, organizational and interpersonal skills, and apply sound scientific and technical experience.
  • Ensure high-quality, timely documentation in electronic laboratory notebooks and technical reports which support regulatory filings.
  • Present data/ strategy to scientists and management internally.Lead, train, and supervise a small team of scientists and junior analysts. Coordinate daily laboratory activities, balance workloads, and ensure project deadlines are met.
  • Ensure accuracy and compliance in executing routine and non-routine testing. Audit analytical results and troubleshoot complex assay or instrument issues.

Position Requirements & Experience:

  • PhD in Immunology, Cell Biology, or related field with at least 2 years of experience or Bachelors/Masters degree in Immunology, Cell Biology, or related field with the equivalent industry experience.
  • Laboratory experience in a variety of analytical methods for the characterization and release of cell-based therapies, include, but not limited to: multi-parametric flow cytometry-based assays for characterization/ release/ stability testing, cell-based cytotoxicity assays, cell-based proliferation assays, cytokine measurements and molecular assays.
  • Hands-on expertise in processing of human peripheral blood mononuclear cells and the isolation and analysis of CAR-T cells and T cell subsets and subpopulations.
  • Proficiency in Spotfire or R is a plus.
  • Familiarity with cGMPs and relevant Regulatory Guidance documents.
  • Strong interpersonal skills including verbal and written communication to work effectively within a collaborative work environment as an individual contributor and as a team member
  • Candidates must be authorized to work in the U.S.

We offer a chance to work with talented people in a collaborative environment and provide a top-notch compensation and benefits package, which includes an annual performance bonus, equity, health insurance, generous time off (including 2 annual holiday company-wide shutdowns) and much more.
