Anti-Mouse TIM-3-BX003 (RMT3-23); Alexa Fluor™ 647-RX003 (T715-25Tests)

Antibody Tim-3, clone RMT3-23, recognizes T cell immunoglobulin and mucin domain-containing protein 3 (TIM3, also known as CD366), a TIM family member of immunoregulatory proteins. Tim-3 is a 60kDa type I transmembrane protein with an extracellular immunoglobulin and mucin-like domain and a cytoplasmic tyrosine phosphorylation motif. Tim-3 is expressed by IFNg-producing Th1 CD4 and Tc1 (cytotoxic) CD8 T cells1, regulatory T cells (Tregs)2, myeloid cells3, NK cells4, and mast cells5. Tim-3 is an inhibitory molecule that limits Th1-mediated inflammatory diseases, including a model of central nervous system inflammation (experimental autoimmune encephalomyelitis, EAE)1, inflammatory bowel disease (IBD)6, and type I diabetes7. Tim-3 is also proposed to induce immunological tolerance7, promote Th1 apoptosis8, and regulate macrophage activation1. In addition, Tim-3 is upregulated on tumor-infiltrating lymphocytes, and coblockade of Tim-3 and immune checkpoint inhibitors, such as PD-1, is currently being investigated in clinical trials for the treatment of cancer9. PhenoCycler-Fusion (CODEX)® reporters are made up of a fluorescent dye and a short oligonucleotide DNA barcode called a CODEX® Tag. Fluorescent reporters enable highly specific detection of corresponding barcodes, and the use of spectrally separated dyes allow for precise signal detection in up to three distinct fluorescence channels at one time.
