IUF - Leibniz-Institut Fur Umweltmedizinische Forschung GMBH

IUF - Leibniz-Institut Fur Umweltmedizinische Forschung GMBH (IUF GMBH) is a non-profit research organization based in Düsseldorf, Germany, registered in the U.S. government's System for Award Management (SAM) since 2014. The organization specializes in environmental health research, with a particular focus on providing advanced scientific services to federal agencies, primarily in the realm of toxicology and neurological research. Specifically, IUF GMBH offers sophisticated in vitro human cell-based assay capabilities that support critical scientific investigations into environmental health and potential neurotoxic compounds.

The organization has consistently provided specialized scientific services to the National Institute of Environmental Health Sciences (NIEHS), primarily through delivery order contracts focused on neurosphere and DTT (presumably developmental toxicity testing) assay services. These contracts, valued between $369,796.88 and $462,670.00, involve complex scientific research supporting the National Toxicology Program's efforts to identify and assess environmental compounds with potential developmental neurotoxicity. The contracts involve high-throughput human neural progenitor cell-derived 3D neurosphere assays capable of simultaneously evaluating multiple neurodevelopmental endpoints. All of these federal contract awards have been issued without specific set-aside designations, indicating open competition.

IUF GMBH holds a single-award indefinite delivery contract (IDV) with NIEHS, valued at $1.3 million and running through June 2026. This IDV was specifically designed to procure human neurosphere assay services and related products to support scientific research. The contract originated from a solicitation seeking sources with extensive experience in optimizing neural assays for screening over 100 compounds. To date, two firm fixed-price delivery orders have been issued against this IDV: one for $406,412.40 for DTT assay products and services, and another for $369,796.88 for human neurosphere assay services. The performance of these contracts takes place entirely in Germany, highlighting the international nature of advanced scientific research procurement by U.S. federal agencies.
