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.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 3 years: -98.6K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
