Description
The RMT3-23 monoclonal antibody specifically recognizes CD366 which is also known as TIM-3 (T-cell immunoglobulin and mucin domain-containing 3, T-cell immunoglobulin mucin receptor 3, or T-cell membrane protein 3). CD366 (TIM-3) is ~31 kDa type I transmembrane glycoprotein encoded by Havcr2 (Hepatitis A virus cellular receptor 2) that belongs to the TIM family within the immunoglobulin superfamily (IgSF). CD366 (TIM-3) is comprised of one Ig-like V-type domain followed by a serine/threonine-rich mucin stalk region in its extracellular region, a transmembrane segment, and a tyrosine phosphorylation motif in its cytoplasmic tail. CD366 (TIM-3) expression is upregulated on subpopulations of activated myeloid cells including macrophages, monocytes, dendritic cells (DC), microglia, mast cells as well as on Type-1 CD4+ (Th1-like) T cells, cytotoxic CD8+ T cells, regulatory T cells (Treg), and natural killer (NK) cells. CD366 (TIM-3) functions as an inhibitory receptor that helps maintain immunological homeostasis and self-tolerance. It may also serve an immune checkpoint molecule that inhibits antitumor immunity and promotes T cell exhaustion. Crosslinking of cell surface CD366 (TIM-3) by Galectin-9 binding downregulates Th1-like and CD8+ T cell responses and can promote Treg or myeloid-derived suppressor cells. CD366 (TIM-3) enables DC to bind phosphatidyl serine expressed by apoptotic cells, phagocytize these cells to suppress inflammation and promote antigen cross-presentation. CD366 (TIM-3) can also bind to high mobility group protein B1 (HMGB1) and inhibit stimulation of the immune response to nucleic acids released by dying tumor cells. RMT3-23 reportedly recognizes CD366 (TIM-3) derived from either BALB/c or C57BL/6 mice that have different Havcr2 polymorphisms.
BD® CompBeads can be used as surrogates to assess fluorescence spillover (compensation). When fluorochrome conjugated antibodies are bound to BD® CompBeads, they have spectral properties very similar to cells. However, for some fluorochromes there can be small differences in spectral emissions compared to cells, resulting in spillover values that differ when compared to biological controls. It is strongly recommended that when using a reagent for the first time, users compare the spillover on cells and BD® CompBeads to ensure that BD® CompBeads are appropriate for your specific cellular application. For optimal and reproducible results, BD Horizon Brilliant™ Stain Buffer should be used anytime BD Horizon Brilliant dyes are used in a multicolor flow cytometry panel. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant Stain Buffer is used in in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant Stain Buffer for the same length of time as the corresponding multicolor panel. More information can be found in the Technical Data Sheet of the BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349) or the BD Horizon Brilliant Stain Buffer Plus (Cat. No. 566385). Note: When using high concentrations of antibody, background binding of this dye to erythroid cell subsets (mature erythrocytes and precursors) has been observed. For researchers studying these cell populations, or in cases where light scatter gating does not adequately exclude these cells from the analysis, this background may be an important factor to consider when selecting reagents for panel(s).
Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions that minimize unconjugated dye and antibody.
1. The production process underwent stringent testing and validation to assure that it generates a high-quality conjugate with consistent performance and specific binding activity. However, verification testing has not been performed on all conjugate lots.
2. Researchers should determine the optimal concentration of this reagent for their individual applications.
3. An isotype control should be used at the same concentration as the antibody of interest.
4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
