Background: T cell Ig- and mucin-domain-containing molecules (TIMs) are a family of transmembrane proteins expressed by various immune cells. TIM-3 is an inhibitory molecule that is induced following T cell activation . TIM-3 is expressed by exhausted T cells in the settings of chronic infection and cancer , and tumor-infiltrating T cells that coexpress PD-1 and TIM-3 exhibit the most severe exhausted phenotype . Tumor-infiltrating dendritic cells (DCs) also express TIM-3. TIM-3 expression on DCs was found to suppress innate immunity by reducing the immunogenicity of nucleic acids released by dying tumor cells . Research studies show that heterodimerization of TIM-3 with CEACAM-1 is critical for the inhibitory function of TIM-3, and co-blockade of TIM-3 and CEACAM-1 enhanced antitumor responses in a mouse model of colorectal cancer . In addition, blockade of TIM-3 in mouse models of autoimmunity enhanced the severity of disease . Finally, binding of Galectin-9 to TIM-3 expressed by Th1 cells induces T cell death .

Purification and Purity: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE).

Specificity: Recognizes endogenous levels of TIM3 protein.

Note: For research use only, not for use in diagnostic procedure.

Extra Notes: Western blot analysis of TIM3 expression in HepG2 (A), BT474 (B), mouse lung (C), mouse thymus (D) whole cell lysates., Immunohistochemical analysis of TIM3 staining in human breast cancer formalin fixed paraffin embedded tissue section. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0). The section was then incubated with the antibody at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
