About the NEPA21

NEPA21 offers organoid researchers a practical, model-matched route to non-viral gene delivery at the stage where speed, flexibility, and experimental timing matter most. It enables teams to test CRISPR perturbations, reporter constructs, mRNA, or other cargoes upstream of longer viral or stable-line workflows, helping them generate fast, assay-ready readouts while preserving control over delivery conditions across diverse organoid systems, including brain, colon, PDO, and organoid-on-chip models. For many groups, the value of NEPA21 is not just delivery itself, but the ability to evaluate hypotheses earlier, optimise conditions around the biology of the model, and move to viral methods only when longer-term stability or tracking is truly required.

Methodologically, the NEPA21 supports dissociated cells (cuvette), intact organoids, and upstream stem/iPSC editing workflows.

What distinguishes the NEPA21 from many competing electroporation systems is its multi-step square-wave pulse design: separate poring and transfer pulses, plus optional polarity exchange, which gives researchers finer control over membrane opening and cargo movement rather than relying on a single simpler pulse event. As the system is not dependant on proprietary special buffers or disposable transfection kits, researchers have greater flexibility to optimise delivery around the biology of the model. In practice, this combination of pulse control, broad compatibility with difficult cell types and tissues, and lower dependence on fixed consumables is a key reason many researchers evaluate NEPA21 for organoid, stem-cell, and other hard-to-transfect workflows, where viability, timing, and model-specific optimisation matter.
