                     AS CHIEF TECHNOLOGY OFFICER

Minneapolis, Minnesota - July 23, 2013 - Techne Corporation (NASDAQ: TECH)
(Techne) announced today that J. Fernando Bazan, Ph.D. has been appointed
Chief Technology Officer. With global recognition as a scientific leader in
fields ranging from structural biology to drug discovery for the treatment of
human disorders, Dr. Bazan will be instrumental in directing innovation and
influencing future growth in Techne's world-wide market.

Dr. Bazan joins Techne with more than twenty years of experience in academia
and the biotechnology industry. Following training at Stanford University,
the University of California Berkeley, and the University of California San
Francisco, he served as a senior scientist at the DNAX Research Institute
(Schering-Plough/Merck) and at Genentech (Roche) as well as serving as Chief
Scientific Officer at NeuroScience, a neuroimmunology startup. Dr. Bazan
holds an adjunct faculty appointment at the University of Minnesota School of
Medicine where he applies pharmacological approaches to cancer and immune
disorders and utilizes structural and computational insights to investigate
signaling mechanisms in biological systems.

As a world renowned scientist, Dr. Bazan has shed light on important
biological questions and set the groundwork for advances in the cell
signaling and immunology fields. His technical expertise, interdisciplinary
approach, and creativity led to the first classification system of the
structural architectures of cytokines and their receptors. Dr. Bazan's
research also produced numerous scientific breakthroughs including the
identification of novel cytokines, their receptor complexes, and immune
subsets (Th17 cells) that responded to these factors. This ability to drive
global technical collaborations will help frame the strategic and platform
decisions for the Company.

"We are delighted to welcome Dr. Bazan to the executive team at Techne," said
Charles R. Kummeth, President and Chief Executive Officer of Techne. "His
