Phenotyping EBV-Infected Cell Lines Using Flow Cytometry

Executive Industry Relevance

Reliable phenotyping of EBV-infected T and NK cell lines using flow cytometry enables precise target validation and mechanistic de-risking in immunology-focused discovery pipelines. Quantitative identification of lineage-specific markers supports predictive confidence in disease-relevant model systems and informs portfolio triage for EBV-associated research programs. This approach strengthens translational continuity from early discovery through preclinical evaluation of immune cell function.
