Stellar Biotechnologies Launches KLH Site(TM)

PORT HUENEME, CA--(Marketwire - Apr 25, 2012) - Stellar Biotechnologies, Inc. ("Stellar") (TSX VENTURE: KLH) (PINKSHEETS: SBOTF) (FRANKFURT: RBT) announced today the launch of KLH Site™ at www.klhsite.com, the first website dedicated to scientific and clinical information on the use of Keyhole Limpet Hemocyanin (KLH) protein.

KLH Site™ is a knowledge base that provides KLH information from around the world, in one convenient place. KLH site™ offers links to biomedical literature and clinical studies, news of KLH-enhanced vaccine development, and useful information on KLH biochemistry and manufacture.

The website centralizes access to the wide-ranging, publicly-available clinical and scientific information that exists on the use of KLH. KLH Site™ will be continuously refreshed with new content as references, research and news become available.

KLH Site™ is sponsored by Stellar Biotechnologies, the world leader in sustainable manufacture of KLH protein. The website targets professionals in immunology, immunotoxicology and vaccine drug development who use KLH as an antigen to assess immune function or as a carrier molecule in therapeutic vaccines.

"KLH is so integral to immunology that the amount of information on its use is vast and growing rapidly," said Frank Oakes, CEO and President of Stellar Biotechnologies. "We created KLH Site™ not only as a convenience to medical and science professionals, but also to assist in identifying trends and data across extensive and diverse KLH-related work."
