CD199 (CCR9) Monoclonal Antibody (BBC3M4), PE, eBioscience™, Invitrogen™

Beskrivning

Description: This BBC3M4 monoclonal antibody reacts with human CD199 (CCR9), a 7 transmembrane spanning G-protein-coupled receptor. CCR9 expression is regulated during thymic development and CCR9 deficiency results in mild impairment in thymocyte development. In the periphery, CCR9 and alpha 4 beta 7 integrin are upregulated in response to dendritic cell-derived retinoic acid, conferring preferential trafficking to gut-associated tissues. CCR9 is the receptor for CCL25 (TECK). Applications Reported: This BBC3M4 antibody has been reported for use in flow cytometric analysis. Applications Tested: This BBC3M4 antibody has been pre-titrated and tested by flow cytometric analysis of stimulated normal human peripheral blood cells. This can be used at 5 μL (0.125 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser. Filtration: 0.2 μm post-manufacturing filtered.

The protein encoded by this gene is a member of the beta chemokine receptor family. It is predicted to be a seven transmembrane protein similar to G protein-coupled receptors. Chemokines and their receptors are key regulators of the thymocytes migration and maturation in normal and inflammation conditions. The specific ligand of this receptor is CCL25. It has been found that this gene is differentially expressed by T lymphocytes of small intestine and colon, suggested a role in the thymocytes recruitment and development that may permit functional specialization of immune responses in different segment of the gastrointestinal tract. This gene is mapped to the chemokine receptor gene cluster region. Two alternatively spliced transcript variants have been described.
