Pel-Freez is a company of dedicated life science professionals located in Rogers, Arkansas.
Originally founded as a backyard rabbit farm by Herman Pelphrey in 1918, the company expanded into animal biologicals in response to the large volume of requests for materials from biomedical researchers in the 1950s, and has been serving the biomedical community ever since.
Over the past 70 years, Pel-Freez has further expanded its offerings to include a variety of animal tissues, extracts, and blood products as well as key human biologicals to support vaccine development and manufacturing, in vitro diagnostics and assays for coagulation, and a range of basic research including immunology, neuroscience, and more.
History of Pel-Freez
From Rabbit Farm to Biological Products
Backyard Rabbit Farm
The story of Pel-Freez begins in 1911, when Herman Pelphrey gave a pregnant pet rabbit named Betsy Ann to his son. Betsy Ann’s litter grew and bred, and soon the Pelphrey home was overrun with rabbits. A natural entrepreneur, Mr. Pelphrey began supplying his neighbors with fresh rabbit meat.
Pel-freez becomes largest rabbit meat supplier in the United States
By WWII, H.F. Pelphrey & Sons had grown into the largest rabbit meat producer in the United States and changed its name to Pel-Freez in order to capture the then-growing trend of frozen foods.
Pel-Freez enters Biological Business
As biomedical research began to take off throughout the 1950s, researchers began contacting Pel-Freez with requests for rabbit tissues and blood, and the Biological Division was subsequently established.
Key Supplier to Researchers Pharmaceutical Companies Worldwide
On March 31, 2020, Pel-Freez was acquired by a private investment partnership led by Dr. Brian Bonk who is now the Pel-Freez President and CEO.
