TIM-3, His, Mouse

Synonyms Hepatitis A virus cellular receptor 2; HAVcr-2; T-cell immunoglobulin and mucin domain-containing protein 3; TIMD-3; T-cell immunoglobulin mucin receptor 3; TIM-3; T-cell membrane protein 3
Description TIM-3 (T cell immunoglobulin and mucin domain-3), also known as HAVCR2, is a 60 kDa member of the TIM family of immune regulating molecules that 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 co-express PD-1 and TIM-3 exhibit the most severe exhausted phenotype. Tumor-infiltrating dendritic cells 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. Its binding to Galectin-9 induces a range of immunosuppressive functions which enhance immune tolerance and inhibit anti-tumor immunity. TIM-3 ligation attenuates CD8+ and Th1 cell responses and promotes the activity of Treg and myeloid derived suppressor cells. In addition, dendritic cell-expressed TIM-3 dampens inflammation by enabling the phagocytosis of apoptotic cells and the cross-presentation of apoptotic cell antigens.
Recombinant Mouse TIM-3 produced in HEK293 cells is a polypeptide chain containing 178 amino acids with C-terminal 6×His. A fully biologically active molecule, rmTIM-3 has a molecular mass of 45 kDa analyzed by reducing SDS-PAGE and is obtained by chromatographic techniques at GenScript.
Source HEK293
Biological Activity Measured by its binding ability in a functional ELISA. Immobilized human Galectin at 0.5 μg/mL (100 μL/well) can bind Biotin-TIM-3 His, Human(Cat.No.Z03402) with a linear range of 0.39-3.125 μg/mL when detected by Streptavidin-HRP. Background was subtracted from data points before curve fitting.

Purity > 97% as analyzed by reducing SDS-PAGE.
Formulation Lyophilized from a 0.2 μm filtered solution in PBS.
Reconstitution Reconstituted in ddH2O or PBS at 100 μg/ml.
Endotoxin Level < 0.2 EU/μg, determined by LAL method.
Storage Lyophilized recombinant TIM-3 remains stable up to 6 months at lower than -70°C from date of receipt. Upon reconstitution, Mouse TIM-3 should be stable up to 1 week at 4°C or up to 3 months at -20°C. For long term storage it is recommended that a carrier protein (example 0.1% BSA) be added. Avoid repeated freeze-thaw cycles.
