Collagen Antibody-Induced Arthritis (CAIA) Model

Collagen Antibody-Induced Arthritis (CAIA) in mice is induced through intraperitoneal injection of a monoclonal antibody cocktail (C-Ab) and lipopolysaccharide. The occurrence of Rheumatoid arthritis in the CAIA mice is determined by parameters such as the increase in arthritis score and mechanical and thermal hyperalgesia. A key advantage of this model is that it can induce RA in many strains of mice which were known to be resilient to the traditional collagen-induced arthritis methods. In addition, the pharmacodynamics evaluation could be completed within a relatively shorter period by using CAIA model. Creative Bioarray provides you with CAIA Model to test the efficacy of novel therapeutics.

Our Capabilities
