Bio-Techne Corp
A maker of the proteins, antibodies, and lab instruments that scientists use to study cells and diagnose disease, Bio-Techne sells brands like R&D Systems and ProteinSimple to researchers worldwide. It began in 1976 in Minneapolis as R&D Systems, making controls to verify blood-analysis machines, and rebranded as Bio-Techne in 2014 — a name blending "bio" with the Greek word "techne," meaning art or craft. Its first product, launched in 1977, was a platelet-rich-plasma control.
