Our customers typically negotiate the terms of those licenses during research and preclinical development. We refer to these arrangements as SPL partnerships, the terms of which contain not only higher annual, non-exclusive license fees for the clinical use of the instrument, but also allow us to share in the economics of the customer’s programs.

Over more than two decades, we have developed and commercialized our proprietary Flow Electroporation platform, which facilitates complex engineering of a wide variety of cells. Electroporation is a method of transfection, or the process of deliberately introducing molecules into cells, that involves applying an electric field in order to temporarily increase the permeability of the cell membrane.
