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 Reported: This F38-2E2 antibody has been reported for use in flow cytometric analysis.
Applications Tested: This F38-2E2 antibody has been pre-diluted and tested by flow cytometric analysis of stimulated normal human peripheral blood cells. This may be used at 5 µL (0.06 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.
Super Bright 780 is a tandem dye that can be excited with the violet laser line (405 nm) and emits at 780 nm. We recommend using a 780/60 bandpass filter. Please make sure that your instrument is capable of detecting this fluorochrome.
When using two or more Super Bright dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Complete Staining Buffer (Product # SB-4401) to minimize any non-specific polymer interactions. Please refer to the datasheet for Super Bright Staining Buffer for more information.
In some experiments, we have observed that compensation values for Super Bright 780-conjugated antibodies are higher in the violet 450/50 channel when using UltraComp eBeads microspheres (Product # 01-2222-42) as compared to single-color stained cells. In such circumstances, we would recommend setting compensation with cells. We have also observed this in some experiments using AbC Total Antibody Compensation beads (Product # A10497).
Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Please protect this vial and stained samples from light.
Fixation: Samples can be stored in IC Fixation Buffer (Product # 00-8222) (100 µL of cell sample + 100 µL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically.
Excitation: 405 nm; Emission: 780 nm; Laser: Violet Laser

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.
