Cell signaling and intracellular interactions begin to change the moment the tissue is removed from the body, making it difficult to measure immune response. Immune cell egress begins almost immediately and functional signaling declines within hours. So even when tissue is viable, the underlying biology is already changing.

elive™ is a first‑in‑class functional platform built to preserve biology not just tissue. Where conventional preclinical ex vivo models oversimplify immune biology and lose important context, elive preserves tissue architecture and immune infiltrates, enabling measurement of dynamic tissue microenvironment dynamics in its native biological context. The result is a more accurate, translationally relevant prediction of therapeutic responsiveness.
