Excellos accelerates gene therapies by improving the quality, breadth, and variance of donor samples, and providing end-to-end cell therapy services: from customized collection to engineered working cell banks. Our proprietary Excellos 360 technology provides deep characterization of cells to better match patient and therapeutic development needs.

The Excellos Story

Our team has extensive experience in cell banking, processing, and manufacturing. As a spin-out of the San Diego Blood Bank, we understand the challenges in collecting quality, consented material and that cell characterization is the foundation for a successful therapeutic. By teaming with Telegraph Hill Partners, we built the dream cell processing and manufacturing facility in downtown San Diego. We embrace our customers not as clients, but as partners- we are in this together!
