What Janvier Labs does

Janvier Labs is a French biotechnology company founded in 1960 that produces, breeds, and sells rodent research models — primarily mice and rats — for preclinical biomedical research. The portfolio spans immunodeficient strains (NRG family), humanized immune system (HIS) and knock-in models (BRGS A2DR2, B6h GLP1R, B6h CA4, B6h SORT1, NXG MHC DKO, NXG FcClarity), metabolic disease models, and aged animals (3 weeks to 24 months), supplemented by a services stack covering custom transgenic creation, colony management, genotyping, speed congenic backcrossing, assisted reproduction, cryopreservation, pre-conditioning (catheterization, DIO diets, induced pathology), and biological products (blood, plasma, serum, organs).

The company operates from a single large production facility in Le Genest-Saint-Isle, France — described on its own website as the most modern rodent production site in Europe — and serves academic research institutions, pharmaceutical and biotechnology firms, and CROs across 17 European countries plus India. Its go-to-market is direct enterprise sales via quote-based pricing, a client portal (Anibio), and an exclusive 2024 distribution partnership with Shanghai Model Organisms Center (SMOC) covering Europe and India. Revenue is not publicly disclosed, and the company remains family-owned with no external investors or funding rounds on record; Thomas Janvier is identified as Publishing Director.

The business model is anchored on one-time unit sales of live or cryopreserved animals, recurring contract breeding and colony management fees, and project-based laboratory services. Quality differentiation rests on documented SPF and SOPF health status, AAALAC-aligned welfare practices, a formal genetic stability policy with genetic certificates on flagship strains, and a standardized microbiota program designed to ensure experimental reproducibility — all critical gating criteria for regulated preclinical research buyers.

Core offering

Janvier Labs produces, breeds, and sells characterized rodent research models (mice and rats), including immunodeficient, humanized, metabolic, and aged strains, for preclinical biomedical research. The company also delivers contract breeding, genotyping, cryopreservation, assisted reproduction, pre-conditioned/catheterized models, biological products, and integrated international logistics to academic, pharmaceutical, biotech, and CRO customers.

Product overview

Janvier Labs is an independent French company (SAS) established in 1960 that produces, breeds, and sells rodent research models for biomedical research. The company operates as a unified product-and-services portfolio organized around four main pillars: (1) Research Models including immunodeficient, humanized, metabolic, and aged animal models; (2) Create & Characterize services for custom transgenic model development; (3) Breed & Secure services encompassing colony management, genotyping, assisted reproduction, cryopreservation, and frozen embryo kits; and (4) Prepare services including pre-conditioned models, catheterization, pathological models, and biological products (blood, organs). The company also provides integrated delivery and repatriation logistics. Key product lines include the NRG immunodeficient series, BRGS A2DR2 humanized models, and various knock-in humanized models (B6h GLP1R, B6h CA4, B6h SORT1, NXG MHC DKO, NXG FcClarity). The company maintains what it claims is the most modern production facility in Europe.
