Automated, Rapid, Point-of-Collection Flow Cytometry for Leukapheresis-Derived Starting Materials: Standardizing Immunophenotyping to Support Cell and Gene Therapy
Introduction – The Accellix Platform provides reliable results at the point of collection through automation, and operators require minimal training and no previous experience. We used a set of healthy donor leukopak samples to compare TBNK cell phenotyping results from the automated TBNK-16 (L) assay to a traditional flow cytometry method and found that cell frequencies correlated strongly, despite differences in instruments, workflow, panel design, and gating methods. Accellix TBNK-16 (L) assay was used to phenotype commercially-available reference material with low variability (CV < 7% across cell the cell phenotypes measured) and maintained accuracy and precision across different assay lots and operators. The Accellix Platform enables automated, standardized characterization of leukapheresis-derived starting material at the point of collection, minimizing process variability and subjective data analysis, and providing rapid leukopak phenotyping for cell therapy development and manufacturing.
