Chondrex, Inc. has been shaping the landscape of arthritis and inflammation research worldwide since 1996. Chondrex was initially focused on providing scientists with the tools necessary to study the pathogenesis of Rheumatoid Arthritis (RA) as well as to develop and screen potential therapeutics for RA. Over the past 20 years however, our scope has expanded beyond just RA research. We now offer a plethora of products ranging from collagen and monoclonal antibody reagents to a wide variety of assay kits for use in allergy, arthritis, connective tissue, and nephritis related research. One such product line, the Collagen Antibody-Induced Arthritis (CAIA) cocktails, allows for faster and more consistent dosage dependent induction of arthritis in mice than the Collagen Induced Arthritis (CIA) model. Furthermore, the CAIA model can be induced in almost all strains of mice, (including CIA-resistant, T-cell deficient, gene knockout, and transgenic mice) whereas the CIA model requires a restricted haplotype. Chondrex is committed to providing the highest quality and most reliable products in order to accelerate the rate of discovery in arthritis and inflammation research.
