PORT HUENEME, CA--(Marketwired - May 15, 2015) - Stellar Biotechnologies, Inc. ("Stellar" or the "Company") (OTCQB: SBOTF) (TSX VENTURE: KLH) today announced that the Company's poster presentation at this week's IMMUNOLOGY 2015 conference, the Annual Meeting of the American Association of Immunologists (AAI), has been posted to the Company's website. http://tinyurl.com/n5hq43w

The poster titled "Measuring the Properties of Different Forms of Keyhole Limpet Hemocyanin (KLH) Reveals Important Differences," represents results from research studies conducted by Stellar on the immunogenicity of different forms and preparations of Keyhole Limpet Hemocyanin (KLH), and relates to the Company's work in developing methods to identify the appropriate functional properties of KLH for use in immunotherapy and immunodiagnostic applications. The results showed significant differences in the efficiency of various types of KLH to elicit KLH-specific and antigen-specific adaptive immune responses.

The poster was authored by Stellar Biotechnologies' scientists Shuguang Bi, Ph.D., Laura Milbrandt, and Catherine Brisson, Ph.D. who attended IMMUNOLOGY 2015 (May 8-12, New Orleans, LA) and represented the Company's products and sustainable KLH manufacturing in an exhibit booth.
