Description
The 7H11 monoclonal antibody specifically recognizes mouse CD370 which is also known as DNGR-1 (Dendritic cell natural killer lectin group receptor 1). CD370 is an ~27 kDa single-pass type II transmembrane glycoprotein that is encoded by Clec9A (C-type lectin domain family member 9A) which belongs to the C-type lectin superfamily. CD370 (Clec9a) is selectively expressed as a disulfide-linked homodimer on plasmacytoid dendritic cells and CD8+ myeloid dendritic cells. This receptor is comprised of an extracellular region that contains a C-type lectin domain with a single carbohydrate recognition domain (CRD), followed by a transmembrane segment and a cytoplasmic tail with an immunoreceptor tyrosine-based activation motif (ITAM). CD370 (Clec9a) acts as a damage-associated molecular pattern receptor, ie, an endocytic receptor for damage-associated molecular patterns (DAMPs) that are expressed by necrotic cells, eg, cells dying due to infection or transformation. This receptor binds by its extracellular domain to exposed F-actin-myosin complexes of dead cells. Intracellular signaling mediated through ligand-bound CD370 (Clec9a) leads to phosphorylation of Syk tyrosine kinase. Further downstream signaling can foster MHC Class I-mediated cross-presentation of dead-cell associated antigens by dendritic cells to CD8+ T cells.
BD™ CompBeads can be used as surrogates to assess fluorescence spillover (Compensation). When fluorochrome conjugated antibodies are bound to 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 CompBead to ensure that BD Comp beads are appropriate for your specific cellular application. For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes are used in the same experiment. Fluorescent dye interactions may cause staining artifacts which may affect data interpretation. The BD Horizon Brilliant Stain Buffer was designed to minimize these interactions. 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). For optimal results, it is recommended to perform two washes after staining with antibodies. Cells may be prepared, stained with antibodies and washed twice with wash buffer per established protocols for immunofluorescent staining prior to acquisition on a flow cytometer. Performing fewer than the recommended wash steps may lead to increased spread of the negative population.
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.
