The Infrastructure Behind the Experiment: Rethinking Research Supply as a Shared Scientific Resource

Modern biomedical research depends on an extensive ecosystem of shared infrastructure that enables investigators to access specialized technologies, expertise, data resources, and biospecimens. Less attention has been given to the operational infrastructure that provides reliable access to the reagents and consumables required for everyday experimental work. Although traditionally viewed as an administrative or procurement function, research supply infrastructure directly influences the cost, timeliness, continuity, and sustainability of scientific activity. This article examines centralized research supply as a form of shared scientific infrastructure through the experience of the Genetic Resources Core Facility at the Johns Hopkins University School of Medicine. What began as a small reagent-access program evolved into an institution-wide research supply infrastructure serving more than 5000 researchers and 846 principal investigators. In 2025, the program provided access to approximately 664,000 products and distributed more than 106,000 laboratory reagents while consolidating purchasing and distribution through a coordinated institutional framework. Over an eleven-year evaluation period, the model also generated substantial estimated institutional economic value through negotiated pricing, reduced shipping costs, and consolidation of purchasing activity. The experience demonstrates that the value of centralized research supply extends beyond procurement efficiency. Integration within a shared-resource environment can improve access to research materials, reduce administrative and logistical barriers, support continuity of experimental workflows, and connect purchasing decisions with scientific expertise and evolving research needs. These findings suggest that research supply can function as shared scientific infrastructure when organized around scientific access, integrated with the research ecosystem, and responsive to evolving investigator needs. Recognizing and strategically integrating this infrastructure within institutional research ecosystems provides an opportunity to strengthen scientific productivity, resilience, and long-term sustainability.
