Description: This F38-2E2 monoclonal antibody reacts with human CD366, also known as T cell immunoglobulin and mucin domain-containing protein 3 (TIM3) or HAVCR2. This cell surface receptor is expressed on activated CD4+ T cell subsets (e.g. Th1, Th17, and Treg), CD8+ T cells, monocytes, dendritic cells, and mast cells. Due to alternative splicing, CD366 exists as membrane-bound and soluble forms. Galectin-9 has been identified as the ligand for CD366. In humans, this receptor negatively regulates CD4+ T cells, influencing the secretion of some Th1- and Th17-related cytokines. CD366 has also been implicated in tolerance, autoimmune disease (e.g. multiple sclerosis), and HIV infection.
Applications Tested: This F38-2E2 antibody has been tested by flow cytometric analysis of stimulated human peripheral blood cells. This can be used at less than or equal to 1 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Storage and handling: Use in a sterile environment.
Filtration: 0.2 µm post-manufacturing filtered.
Purity: Greater than 90%, as determined by SDS-PAGE.
Endotoxin Level: Less than 0.001 ng/µg antibody, as determined by LAL assay.
Aggregation: Less than 10%, as determined by HPLC.
TIM3 (Hepatitis A virus cellular receptor 2, HAVCR2, T-cell immunoglobulin, mucin-dmain containing-3) is a 281 amino acid long, Type-1 Th1- specific cell surface glycoprotein expressed on terminally differentiated CD4+Th1 and CD8+Tc1 cells. TIM3 consists of an IgV-like domain, a mucin-like domain in the extracellular region, and a conserved Tyrosine phosphorylation motif in the cytoplasmic region. TIM3 is involved in macrophage activation and induction of autoimmune diseases. Further, TIM3 down-regulates aggressive Th1-mediated immune responses and facilitates in the development of immune tolerance. Pathological significance of TIM3 has been attributed to Experimental autoimmune encephalomyelitis (EAE), a Th-1 dependent autoimmune disease, and also enhances the severity of experimental autoimmune encephalomyelitis in mice.
