Built on the foundation of the San Diego Blood Bank (SDBB), Excellos supplies current good manufacturing practices (cGMP) cellular products and services, together with process development and manufacturing expertise, to scientists and clinicians working with cell and gene therapies. The company's collection network consists of nine SDBB centers in the San Diego area that see an average of over 70,000 diverse donors annually, as well as exclusive access to select, consented material from SDBB's public cord blood bank.

Excellos also has access to a nationwide collection network, giving it one of the largest cellular material procurement portfolios, the firm said. Connecting its collection network to cGMP and R&D facilities in San Diego, Excellos provides a full suite of end-to-end capabilities to facilitate the development and manufacture of autologous and allogeneic cell therapies. Excellos' experience includes working with therapeutic companies developing CAR-engineered T cells, tumor-infiltrating lymphocytes, and providing isolated immune cells integral to the advancement of immunotherapies.
