Optimized cell counting and viability analysis of large, complex A172 glioblastoma cells using the SpectraSlide AP-1 and LUNA-FX7™ automated cell counter
26 Nov 2025Accurate assessment of cell concentration and viability is vital in cancer research, drug development, and immunotherapy, underpinning the evaluation of experimental outcomes and therapeutic efficacy. However, cell models with large and complex morphologies—such as A172 glioblastoma cells—are challenging to analyze with standard viability assays.
In this study, we compared the SpectraSlide® AP-1 and PhotonSlide™ for cell concentration and viability analysis. Using the A172 glioblastoma cell model, we validated the precision and performance of the SpectraSlide® AP-1.
