# Prellis Biologics

> Berkeley, California biotechnology company discovering fully human antibody therapeutics
> by pairing wet-lab human immunology with machine learning. Its EXIS (Externalized Immune
> System) platform uses LNO lymph node organoids — 3D tissue printed with holographic
> two-photon photolithography — to recreate human lymph node biology in vitro, raise true
> human antibody responses across genetically diverse donors, and feed the resulting
> sequence and characterization data into generative AI models that predict and optimize
> candidates in an iterative lab loop.
