About InVivoMAb anti-mouse TIM-3 (CD366)The B8.2C12 monoclonal antibody reacts with mouse TIM-3 (T cell immunoglobulin and mucin domain-3) also known as CD366. This antibody binds to the BALB/c allele of TIM-3 while reactivity to the C57Bl/6 allele is significantly weaker. TIM-3 is a 60 kDa member of the TIM family of immune checkpoint receptors and exists as a type I transmembrane glycoprotein with a mucin-like domain in its extracellular portion and a tyrosine phosphorylation motif in its cytoplasmic portion. TIM-3 is specifically expressed at high levels on the surface of Th1 lymphocytes whereas Th2 lymphocytes express TIM-1 and TIM-2. TIM-3 activation occurs via binding to the cell-associated C-type lectin galectin-9. Upon binding TIM-3 induces apoptosis of Th1 cells. Inhibition of TIM-3 signaling in mice has been shown to exacerbate experimental autoimmune encephalomyelitis, promote IFNγ production and Th1 cell proliferation. Tim-3 has also been shown to be required for the induction of tolerance, as both TIM-3 knockout animals and mice treated with TIM-3-Ig fusion protein display defects in the induction of antigen-specific tolerance. Additionally, TIM-3 signaling is currently being explored as a cancer immunotherapy target as CD8 T cells which express both TIM-3 and PD-1 exhibit greater defects in both cell-cycle progression and effector cytokine production than cells that express PD-1 alone.InVivoMAb anti-mouse TIM-3 (CD366) SpecificationsIsotypeRat IgG1, κRecommended Isotype Control(s)InVivoMAb rat IgG1 isotype control, anti-horseradish peroxidase(BE0088)Recommended InVivoPure Dilution BufferInVivoPure pH 7.0 Dilution Buffer(IP0070)ImmunogenMouse Tim-3 protein/Freund adjuvantReported Applicationsin vivo TIM-3 neutralizationin vitro TIM-3 blockingFlow cytometryEndotoxin<2EU/mg (<0.002EU/μg)Determined by LAL gel clotting assayPurity>95%Determined by SDS-PAGEFormulationPBS, pH 7.0Contains no stabilizers or preservativesSterility0.2 μM filteredProductionPurified from tissue culture supernatant in an animal free facilityPurificationProtein GStorageThe antibody solution should be stored at the stock concentration at 4°C.
