Prellis Biologics

Prellis Biologics is a Berkeley, California biotechnology company that discovers fully human antibody therapeutics by combining 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. The company sells antibody discovery collaborations and licensed therapeutic programs to pharmaceutical partners rather than software, and publishes no public developer program, API, SDK, or machine-readable specification.

Prellis Biologics is profiled on the APIs.io network. Tagged areas include Company, Biotechnology, Life Sciences, Antibody Discovery, and Drug Discovery.

Prellis Biologics’ developer surface includes engineering blog, support, and 6 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
