## Knowledge Hub

- [Knowledge Hub](https://www.nanoentek.eu/en/knowledge): Method explainers and protocols with peer-reviewed references.
- [AO/DAPI Dual-Staining Cell Counting](https://www.nanoentek.eu/en/knowledge/ao-dapi-dual-staining-cell-counting): AO is membrane-permeable and stains all nucleated cells; DAPI only enters cells with a compromised plasma membrane, so the AO−DAPI difference equals viable cell count [1,2]. (last reviewed 2026-04-30)
- [Trypan Blue vs. AO/DAPI: A Method Comparison for Viability](https://www.nanoentek.eu/en/knowledge/trypan-blue-vs-ao-dapi): Trypan blue is fast and cheap but cannot distinguish nucleated cells from debris, platelets or RBCs in primary samples [1,2]. (last reviewed 2026-04-30)
- [Apoptosis vs. Necrosis in Live-Cell Imaging](https://www.nanoentek.eu/en/knowledge/apoptosis-vs-necrosis-live-cell-imaging): Apoptosis is an active, ATP-dependent programme with characteristic morphology (membrane blebbing, nuclear fragmentation) and intact membranes until late stages [1,2]. (last reviewed 2026-04-30)
- [CAR-T Cell Analysis: Concentration, Viability and Phenotype](https://www.nanoentek.eu/en/knowledge/car-t-cell-analysis): Total nucleated cell concentration and viability are critical quality attributes (CQAs) at every step of autologous CAR-T manufacturing [1,2]. (last reviewed 2026-04-30)
- [Electroporation of Hard-to-Transfect Cell Lines](https://www.nanoentek.eu/en/knowledge/electroporation-hard-to-transfect-cells): Electroporation creates transient aqueous pores in the plasma membrane; pore size and lifetime depend on pulse field strength and duration [1,2]. (last reviewed 2026-04-30)
- [Residual White Blood Cell Counting in Blood Products](https://www.nanoentek.eu/en/knowledge/residual-white-blood-cell-counting): EU and US standards require <1×10⁶ residual leukocytes per leukoreduced blood component [1,2]. (last reviewed 2026-04-30)
