The NanoSpark GROW-NK Soluble Activator is a culture-ready, feeder-free reagent for in vitro activation and expansion of human NK cells. The nanoscale of the NanoSpark GROW-NK protein complex allows for sterile filtration and removal of excess reagent via either media exchange or simple centrifugal cell washing.
There is no other product like it. It’s simple, easy-to-use, and removes the need for costly, laborious, and risky feeder cells. Competing feeder cells introduce clinical risks to the process by contaminating cell therapies with cancer cells that could also harbor human pathogens.
The NanoSpark™ product line is modular and plug-and-play by design, using a proprietary self-assembly protein nanoparticle complex that is inherently soluble and can be filter sterilized.
The NanoSpark™ GROW-NK Soluble Activator contains self-assembling protein nanoparticles (complexes) with functional antibodies bound to the surface through high-affinity non-covalent interactions. These anti-NKp46 and anti-CD2 antibodies are arranged in a proprietary biophysical combination on the NanoSpark™ platform that drives internal signal transduction or activation.
The NanoSpark™ GROW-NK Soluble Activator activates resting donor human CD3-/CD56+ NK cells.

The underlying NanoSpark™ platform has undergone biocompatibility testing when formulated with antibodies specific to our T cell activator, STEM-T, which we consider a significant derisking step for the platform as a whole. The details are as follows:
The composition of the NanoSpark™ reagent is protein-based, and consequently naturally biodegradable, which provides a significant safety advantage over magnetic bead-based and synthetic products. A reputable medical device CRO was commissioned to complete the in vitro & in vivo ISO 10993 biocompatibility testing. The tests were run at >20X the predicted possible carry-over amount, which resulted in no toxicity or adverse effects:
| ISO 10993 Biocompatibility Testing | Test | Type of Test | Result | Product Tested |
| ISO 10993-5 | Cytotoxicity | In vitro | No Toxicity/Adverse Effect | NanoSpark STEM-T |
| ISO 10993-10 | Sensitization | In vivo: Guinea Pig | No Toxicity/Adverse Effect | NanoSpark STEM-T |
| ISO 10993-10 | Irritation/Intracutaneous Reactivity | In vivo: Rabbits | No Toxicity/Adverse Effect | NanoSpark STEM-T |
| ISO 10993-11 | Acute Systemic Toxicity | In vivo: Mice | No Toxicity/Adverse Effect | NanoSpark STEM-T |
| ISO 10993-11 | Pyrogenicity | In vivo: Rabbits | No Toxicity/Adverse Effect | NanoSpark STEM-T |
