DatasheetSpecific ReferencesReviewsRelated ProductsProtocols
Materials provided
Capture Ab:0.2 mg/mL of rabbit anti-TIMD3 monoclonal antibody, Dilute to a working concentration of 2 μg/mL in CBS before coating.
Detection Ab:0.25 mg/mL mouse anti-TIMD3 monoclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to working concentration of 1 μg/mL in detection antibody dilution buffer before use.
Standard:Each vial contains 70 ng of recombinant TIMD3. Reconstitute with 1 mL detection antibody dilution buffer. After reconstitution, store at -20℃ to -80℃ in a manual defrost freezer. A seven-point standard curve usi ng 2-fold serial dilutions in sample dilution buffer, and a high standard of 2 ng/mL is recommended.
Sensitivity
The minimum detectable dose of Human TIM-3 / HAVCR2 / TIMD3 was determined to be approximately 31.25 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.
Principle of the product
The Human TIM-3 / HAVCR2 / TIMD3 ELISA Pair Set is for the quantitative determination of Human TIM-3 / HAVCR2 / TIMD3.
This ELISA Pair Set contains the basic components required for the development of sandwich ELISAs.
The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for TIM-3 / HAVCR2 / TIMD3 coated on a 96-well plate. Standards and samples are added to the wells, and any TIM-3 / HAVCR2 / TIMD3 present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated rabbit anti-TIM-3 / HAVCR2 / TIMD3 monoclonal antibody is then added, producing an antibody-antigen-antibody "sandwich". The wells are again washed and TMB substrate solution is loaded, which produces color in proportion to the amount of TIM-3 / HAVCR2 / TIMD3 present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.
Storage
Capture Antibody: Aliquot and store at -20℃ to -80℃ for up to 6 months from date of receipt. Avoid repeated freeze-thaw cycles.
Detection Antibody: Protect it from prolonged exposure to light. Aliquot and store at -20℃ to -80℃ and for up to 6 months from date of receipt. Avoid repeated freeze-thaw cycles.
Standard: Store lyophilized Standard at -20℃ to -80℃ for up to 6 months from date of receipt. Aliquot and store the reconstituted Standard at -80℃ for up to 1 month. Avoid repeated freeze-thaw cycles.
Background

Hepatitis A virus cellular receptor 2 (HAVCR2), formerly known as T cell immunoglobulin and mucin domain-3 (TIM-3), is a transmembrane glycoprotein expressed on the surface of terminally differentiated Th1 cells but not on Th2 cells. It was the first surface molecule that specifically identifies Th1 cells in both mice and human. Recently, identification of Galectin-9 as a ligand for TIM-3 has established the TIM-3-Galectin-9 pathway as an important regulator of Th1 immunity and tolerance induction. Engagement of Tim-3 by its ligand galectin-9 negatively regulates IFN-gamma secretion and influences the ability to induce T cell tolerance in both mice and man. It suggests a novel paradigm in which dysregulation of the TIM-3-galectin-9 pathway could underlie chronic autoimmune disease states, such as multiple sclerosis. Recent work has explored the role of TIM-3 in systemic lupus erythematosus (SLE), and their results indicate that TIM-3 may represent a novel target for the treatment of SLE. Numerous studies have demonstrated that Tim-3 influences autoimmune diseases, including diabetes and multiple sclerosis, and its role in other inflammatory diseases including allergies and cancer is beginning to become clear. In tumor rejection model, soluble form of Tim-3 (sTim-3) significantly impaired T cell antitumor immunity, evidenced by decreased antitumor CTL activity and reduced amount of tumor-infiltrating lymphocytes in tumor. sTim-3 as an immunoregulatory molecule that may be involved in the negative regulation of T cell-mediated immune response.
