Anti-Bacterial Antibodies

Recent studies indicate that environmental factors, especially intestinal microbiota and their toxins, may play pathogenic roles in autoimmune diseases such as rheumatoid arthritis (RA) 1-7), inflammatory bowel diseases (IBDs) (8, 9), systemic lupus erythematosus (SLE) (10) and other chronic disorders (11-13).  Moreover, it is considered that increased translocation of bacteria and bacterial toxins associated with high mucosal permeability and low immune function may be the primary and common pathogenesis of autoimmune disorders (14). To facilitate research in this field, Chondrex offers several mouse anti-bacterial monoclonal antibodies, as well as ELISA kits to detect anti-bacterial antibodies in humans and mice.

Usage Tips:
Chondrex strongly recommends using ChonBlock buffer to minimize non-specific false-positive and false-negative reactions, especially when working with antibodies against environmental factors.
