Tim3 (T Cell Immunoglobulin and Mucin Domain-containing 3, T Cell Immunoglobulin Mucin 3, TIM3, TIM-3, TIMD3, FLJ14428, Hepatitis A Virus Cellular Receptor 2, HAVCR 2, HAVCR2, HAVCR-2, Kidney Injury Molecule 3, KIM-3) (APC)

T cell immunoglobulin mucin-3 (Tim3) is a member of the T cell Immunoglobulin- and Mucin-domain-containing family of type I membrane glycoproteins that regulate autoimmune and allergic disease. Tim3 is selectively expressed on Th1 cells and interacts with galectin-9. It negatively regulates Th1 responses and affects macrophage activation. The 280aa mature human Tim3 contains a V-type Ig-like domain that shows multiple polymorphisms, followed by a mucin-like domain in the 171aa extracellular region, which shares 60% aa identity with the mouse Tim3 ECD. One splice variant is truncated within the mucin domain and presumably is secreted. \n\nApplications: \nSuitable for use in Flow Cytometry. Other applications not tested.\n\nRecommended Dilution:\nFlow Cytometry: 10ul labels up to 1x10e6 cells. Validated using whole blood monocytes.\nOptimal dilutions to be determined by the researcher.\n\nFlow Cytometry Protocol:\n1. Cells may be Fc-blocked with 1ug of human IgG/10e5 cells for 15 minutes at RT. Do not wash excess blocking IgG from this reaction.\n2. After blocking, add 10ul of T5469-92F to up to 1x10e6 cells and incubate for 30 minutes at RT\n3. Remove unbound antibody by washing the cells twice in Flow Cytometry Staining Buffer (Catalog #F4568-10). Note that whole blood requires a RBC lysis step at this point using Flow Cytometry Human Lyse Buffer.\n4. Resuspend the cells in Flow Cytometry Staining Buffer for final flow cytometric analysis. As a control for this analysis, cells in a separate tube should be treated with APC-labeled rat IgG2A antibody. \n\nStorage and Stability:\nMay be stored at 4 degrees C before opening. DO NOT FREEZE! Stable at 4 degrees C as an undiluted liquid. Stable for at 12 months at 4 degrees C. Freezing allophycocyanin conjugates will result in a substantial loss of activity. Allophycocyanin conjugates are sensitive to light.
