Our journey began with a mission to lower risk in cell therapy development and regulatory submission, ensuring safer therapies reach patients faster. To achieve this, we developed cutting-edge on-target and off-target assessment assays, providing unparalleled insights into genomic integrity. These innovations drive precision medicine forward, empowering safer, more effective therapeutic advancements.
