We discover, develop, manufacture, and sell veterinary vaccines based upon proprietary SRP^® Technology. The innovative SRP^® Technology is based on inducing host immunity against certain cell wall components of common Gram (-) and Gram (+) bacteria. These cell wall antigens are called "Siderophore Receptors and Porins" (SRP's). Our SRP^® Technology is protected by an extensive portfolio of U.S. and international patents.
