Bio-Techne Corporation, originally founded as Techne Corporation in 1976, has a history rooted in the evolution of modern molecular biology and the demand for high-quality research tools. It started as a specialized company focused on developing and manufacturing diagnostic reagents, but it rapidly expanded its footprint through strategic research and development and the acquisition of iconic brands like R&D Systems, which established the company’s reputation as the gold standard in protein reagents. Over the last four decades, the company has transformed from a niche supplier into a major multinational life sciences conglomerate. Through successive acquisitions of companies specializing in protein analysis, diagnostic tools, and cell therapy reagents, it has built an end-to-end portfolio that supports the entire lifecycle of pharmaceutical and biological research, moving from the earliest stages of academic discovery into the highly regulated world of industrial therapeutic and clinical manufacturing, cementing its role as a bedrock of the modern biotechnology infrastructure.
