Lauridsen Group

Lauridsen Group is a privately held U.S.-based holding company that owns a portfolio of independent businesses focused on functional proteins and related ingredients for food, animal nutrition, health, and life science markets. Its subsidiaries supply products used across human and animal health, diagnostics, biopharmaceutical manufacturing, veterinary vaccines, nutraceuticals, pet food, and agricultural applications. In the healthcare-adjacent segment, Lauridsen Group is best known through businesses such as Proliant Health & Biologicals, which provides plasma fractions, bovine serum albumin, and animal-derived extracts for diagnostic, cell culture, and bioprocessing applications. The company is not a therapeutic drug developer and does not appear to operate a clinical pipeline; rather, it is a commercial-stage manufacturer and supplier of specialty protein ingredients. Lauridsen Group traces its roots to 1916 and remains family-owned, with global manufacturing and sales operations.
