Anti-TIM-3, clone RMT3-23, Azide Free Antibody

The protein called Hepatitis A virus cellular receptor 2 (HAVcr-20), T-cell immunoglobulin and mucin domain-containing protein 3 (TIMD-3), T-cell immunoglobulin mucin receptor 3 (TIM-3), or T-cell membrane protein 3 and encoded by the human gene HAVCR2/TIM3/TIMD3 is an important protein in the regulation of macrophage activation. TIM-3 is also critical for immune tolerance as it inhibits T-helper type 1 (Th1) mediated auto and alloimmune responses. Finally TIM-3 plays an important role in T-cell homing in the thymus and lymph and is the receptor for the Galectin-9 an important protein modulating cell-cell and cell matrix interactions. TIM-3 is a membrane bound protein that is expressed largely by immune system cells. High TIM-3 expression is also associated with many tumors including renal cancer and acute myelogenous leukemia (AML), and its expression is also a target for anti-cancer therapy as anti-TIM-3 antibodies have been shown to eradicate leukemic stem cells (LSCs) in animal models of AML.

Recombinant protein corresponding to mouse TIM-3.

Inhibits Activity/Function Assay: Co-administration of a representative lot by an independent laboraotory with FVAX significantly suppressed tumor growth to a greater extent than FVAX alone. Treatment with Anti-TIM-3 , clone RMT3-23, Azide Free also augmented antitumor activities of plasmid DNA encoding melanoma target gp100 or TRP2, suggesting that targeting TIM-3 or TIM-4 improves antitumor activiites of other forms of cancer vaccines.

Flow Cytometry Analysis: 1 µg from a representative lot detected TIM-3 in TIM-3 transfected 1X10E6 BALB/L5178Y cells.

Flow Cytometry Analysis: A representative lot detected TIM-3 in dendritic cells, macrophages, splenocytes, and hepatic mononuclear cells from acute graft-vs-host disease (aGVHD) mice (Oikawa, T., et al. (2006). J Immunol. 177(7):4281-4287.).

Immunohistochemistry Analysis: A representative lot from an independent laboratory detected TIM-3 in liver tissue from normal and aGVHD mice (Oikawa, T., et al. (2006). J Immunol. 177(7):4281-4287.).

Immunocytochemistry Analysis: A representative lot from an independent laboratory detected TIM-3 in HMGB1-deficient MEF cells (Chiba, S., et al. (2012). Nat Immunol. 13(9):832-842.).

This Anti-TIM-3 antibody, clone RMT3-23, Azide Free is validated for use in western blotting, flow cytometry, IHC, ICC & Inhibits activity/Function for the detection of TIM-3.

Evaluated by Western Blotting in TIM-3 transfected L5178Y cell lysate.
