Description
The ER-TR9 monoclonal antibody specifically recognizes mouse CD209 antigen-like protein B (CD209b) which is also known as Mouse SIGN-related 1 (mSIGNR1 or SIGNR1). CD209b is a mouse homolog of human CD209 (DC-SIGN) and is also referred to as DC-SIGN-related protein 1 (DC-SIGNR1). CD209b is an ~37 kDa type II transmembrane glycoprotein that is encoded by Cd209b (CD209b antigen) which belongs to the C-type lectin family. It contains a single C-terminal C-type lectin domain and is involved in the recognition of microbial polysaccharides. CD209b is expressed on macrophages residing in the splenic marginal zone, the medullary and trabecular sinuses of lymph nodes, and peritoneal cavity. CD209b is involved in the clearance and innate immune responses to microbial molecules including polysaccharides and lipopolysaccharides (LPS) and the uptake of encapsulated microbes. It may also affect leucocyte migration through its adhesive interaction with CD54 (ICAM-2).
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). For optimal results, it is recommended to perform 2 washes after staining with antibodies. Cells may be prepared, stained with antibodies and washed twice with wash buffer per established protocols for immunofluorescence staining, prior to acquisition on a flow cytometer. Performing fewer than the recommended wash steps may lead to increased spread of the negative population.
The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated to the dye under optimum conditions and unconjugated antibody and free dye were removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.
