REACTION BIOLOGY CORPORATION

Reaction Biology Corporation specializes in high-throughput biochemical and cellular assays for drug discovery, with deep expertise in kinase inhibition profiling and ion channel screening. The company delivers precision pharmacological testing using advanced platforms such as gamma-33P ATP kinase assays and NanoBRET technology to evaluate compound potency, selectivity, and mechanism of action against targeted enzyme panels. Their technical capabilities extend to functional characterization of small molecules across complex biological systems, enabling early-stage de-risking of therapeutic candidates for oncology, immunology, and cardiovascular indications. Differentiators include validated assay protocols, robust data integrity, and experience supporting regulatory-ready preclinical development workflows for government and pharmaceutical partners. The contractor maintains a consistent, long-standing relationship with the Department of Health and Human Services, providing specialized laboratory services that support public health research and biomedical innovation. Work performed under HHS contracts centers on evaluating novel compounds for kinase target engagement and cardiac safety profiles, aligning with NIH and FDA-related drug development initiatives. This recurring engagement reflects a trusted partnership in generating high-quality, reproducible pharmacological data critical to advancing therapeutic pipelines. Reaction Biology Corporation operates primarily under NAICS 541380, which encompasses specialized testing laboratories serving the life sciences sector. Their market positioning is defined by niche expertise in biophysical and biochemical screening services for pharmaceutical and government research programs, particularly in kinase biology and cardiotoxicity assessment. They serve as a critical external resource for agencies requiring scalable, GXP-aligned analytical capabilities beyond in-house capacity. The company is structured as a 2L entity headquartered in Malvern, Pennsylvania, with no publicly disclosed federal certifications. Its geographic presence is focused on the mid-Atlantic region, supporting federal research missions through agile, science-driven laboratory operations.
