What makes RoukenCells’ IndEx‑2 cell lines different from standard inducible systems?

IndEx‑2 allows independent, finely tunable expression of one or two antigens, enabling researchers to map activation thresholds and model real‑world therapeutic behaviour more accurately than single‑inducer systems.

Do CHOK1 cell lines require a US import permit?

Yes. In most cases, CHOK1 cell lines require a US import permit issued by the U.S. Fish & Wildlife Service (FWS).

CHOK1 cells are derived from the Chinese hamster (Cricetulus griseus). Under US
regulations, hamsters are classified as wildlife, rather than domesticated animals. As a result, shipments containing actual CHOK1 cells or cell cultures are subject to
oversight by the U.S. Fish & Wildlife Service.
