Acute Phase Protein Detection

Acute phase proteins (APPs) are blood proteins that are an integral part of acute phase responses (APR).  The APR is a part of the innate host defense system which is triggered by tissue damage and inflammation caused by infectious, immunologic, or neoplastic agents.  Of the well-characterized APPs, C-reactive protein (CRP) and serum amyloid A (SAA) levels are significantly elevated after inflammatory irritation, surgical trauma, or inflammatory diseases, and as such are used for routine testing to detect inflammation in many diseases (1-9).

Chondrex, Inc provides a canine CRP ELISA kit (Catalog # 6027) and a serum feline SAA ELISA detection kit (Catalog # 6028) which can be used to detect and monitor inflammation, as well as in studies investigating inflammation.  Furthermore, anti-CRP and SAA monoclonal antibodies are available.  Please refer to the product pages for more information.
