About SciXchange

Building toward trusted infrastructure for scientific material sharing.

SciXchange is an early-stage, non-commercial prototype exploring how scientific materials can become easier to discover, request, and credit across labs.

Papers have preprint servers. Code has GitHub. Scientific materials still move through inboxes, personal networks, and freezer inventories. SciXchange is building toward a trusted, credit-aware exchange layer for the materials that make experiments possible.

Across research labs, scientists spend months developing proteins, plasmids, cell lines, compounds, antibodies, protocols, and other specialized materials. After a paper is published or a project ends, many of those resources become hard to find, even when they could help another lab move faster.

The bottleneck is not generosity. It is infrastructure: discovery, trust, attribution, and compliance are scattered across informal emails and personal networks.

Creator's Note

Why I started SciXchange.

I've spent countless nights perfecting protein purifications, optimizing cell lines, and synthesizing compounds — only to watch them sit unused after publication. Meanwhile, across the hall or across the world, another researcher is starting from scratch on the same materials I've already mastered.

During my PhD and postdoc, I have spent years developing proteins, DNA constructs, and experimental protocols that became less visible once the project moved on. I have also watched other researchers spend weeks or months rebuilding materials that already existed somewhere else.

SciXchange grew from that frustration: a belief that the materials behind science should be easier to find, request, and credit. The long-term goal is not just a marketplace, but a trust and attribution layer for scientific collaboration.

Current status. SciXchange is currently an early-stage, non-commercial prototype. It is not incorporated, has no revenue, and has no employees. The project is independent of Longfu Xu's academic research at UC Berkeley / HHMI.

Help shape SciXchange.

SciXchange is at the prototype stage. I'm looking for conversations with researchers, lab managers, tech transfer experts, and builders who have lived the friction of finding, requesting, sharing, or crediting scientific materials.
