Project Title: Purified PRRS Viral Proteins

Institutions: ATG Laboratories, Inc. and Dept. of Veterinary & Biomedical Sciences, University of Minnesota

Outcome/Results: Specific proteins were produced for the sole purpose of being made available to any cooperating researcher on an as needed basis at no charge to the researcher.

In order to facilitate study of the PRRS virus by creating a stock of purified viral proteins, PRRS virus proteins that stimulate the immune system in pigs were expressed and purified. Specific proteins are now available to PRRS researchers and can be used to detect exposure to PRRS virus, monitor immune responses, and to investigate mechanisms of immune protection against PRRS.
