When it comes to cell therapy, your starting material can make all the difference — not just in outcomes, but in efficiency, reproducibility, and long-term success. At Excellos, we believe the quality and consistency of your donor material should never be an afterthought.

Through our deep partnership with San Diego Blood Bank, we offer more than access — we offer insight. Insight into a diverse, consented, and recallable donor pool with detailed, real-world data that supports your science at every step. From early-stage discovery to longitudinal studies, Excellos provides starting material that’s purpose-built to match the needs of your program.
