The CCR9 receptor is a G protein-coupled seven-transmembrane receptor expressed on thymocytes and other intestine-homing cells. It has been proposed that CCR9 is necessary to allow lymphocytes access to intestinal sites. Drugs that block CCR9 from binding with its chemokine ligand CCL25 or TECK may be useful treatments for inflammatory bowel diseases. Six monoclonal antibodies that detect murine CCR9 have been generated.
Antibody: Monoclonal Anti-Mouse CCR9 Antibodies
Preparation: CCR9-deficient mice were immunized with murine thymocytes expressing native CCR9. B cells from the immunized mice were fused to a murine myeloma to produce six hybridoma clones.
Specificity: Native murine CCR9. No cross-reactivity with human and rat CCR9.
Purification: Hybridoma supernatants were purified by protein A/protein G affinity chromatography.
Tested application: Flow cytometry. Immunohistochemistry.
Utility: Quantification of cells bearing native CCR9 on its surface. Quantification of CCR9 down-regulation upon exposure of CCR9-bearing cells to CCR9 ligand.
Materials available: Six clones

Since these anti-mouse antibodies are of mouse origin, they will be tolerated upon injection into mice and may be helpful in animal models to assess the usefulness of potential drugs that block CCR9 function.
