The antibody was purified by affinity chromatography, and conjugated with Alexa Fluor® 647 under optimal conditions. The solution is free of unconjugated Alexa Fluor® 647.
Storage & Handling:
The antibody solution should be stored undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
Application:
FC - Quality tested
Recommended Usage:
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For immunofluorescent staining, the suggested use of this reagent is 5 µl per million cells or 5 µl per 100 µl of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.

Human CD199, also called as CCR9, is a member of the G protein coupled receptor family and is involved in T cell development in the thymus and in gut-associated immune response. The interaction of CCR9 with its ligand CCL25 (TECK, thymus-expressed chemokine) may direct the trafficking of developing T cells in the thymus and generation of gut-specific immunological memory.
Other Names:
GPR 9-6, CDw199, Chemokine Receptor 9
Structure:
A membrane of G-protein coupled receptors and contains seven transmembrain domains. Human CCR9 has above 80% amino acid sequence homology with mouse counterpart.
Distribution:
Highly expressed on different stages of thymocytes and upregulated on CD4+CD8+ cells. It is expressed to a much lower level on spleen and lymph node cells. Expression of CCR9 on gamma/delta T cells in the intraepithelial and small intestine is reported.
Ligand Receptor:
CCL25
Interaction:
CCL25
