Sampling in PBS-Mini
This video explains how to collect a representative sample from a PBS Mini culture for offline analysis, including cell counts and imaging. It covers sample-volume and frequency considerations, dedicated base use in a biosafety cabinet, and temporary agitation adjustments to eliminate unmixed regions before sampling. Viewers also learn the recommended pipette position and why the target volume should be collected in one continuous pull to improve sample consistency and data quality. The selected sampling speed is specific to the culture and vessel setup.
This application note demonstrates the benefits of PBS Biotech’s PBS-Mini Vertical-Wheel® Bioreactor within a scalable workflow developed with Bio-Techne for hiPSC expansion and differentiation into functional pancreatic islet-like clusters. The bioreactor supported robust aggregate culture while maintaining more than 95% pluripotency during hiPSC expansion and supporting progression through key stages of pancreatic differentiation. Combined with Bio-Techne’s GMP-grade reagents and analytical solutions, the workflow generated beta cell-containing, functional islet-like clusters that…
This webinar examines scalable suspension culture of PSC-derived organoids using PBS Biotech Vertical-Wheel bioreactors. PBS Applications Engineer, Hannah Worden, explains how low-shear, homogeneous mixing and consistent geometry support organoid process development and scale-up. Case studies cover liver, pancreatic islet, and cerebellar organoids, including aggregate-size control, differentiation, functional markers, and improved organization under dynamic culture. With the audience, we address agitation, seeding density, media formulation, perfusion-based medium exchange, sampling, and…
This poster, presented at ISSCR Kyoto 2026, demonstrates a scalable strategy for iPSC manufacturing using Vertical-Wheel Bioreactors, addressing expansion, process development, cell banking, and differentiation. Linear scale-up from PBS-0.1 through PBS-80 produced 200 billion iPSCs at a 50 L working volume while maintaining pluripotency and normal karyotype. High-density work cell banks were developed through 3D adaptation and retained differentiation potential toward cardiomyocytes and pancreatic progenitors. MiniPRO further served as a controlled scale-down model, demonstrating growth…
