BV510 Rat Anti-Human Lgr5 (N-Terminal)
BV510 Rat Anti-Human Lgr5 (N-Terminal)

Flow cytometric analysis of LGR5 expression on human LGR5-transfected cells. Human LS-174T colorectal adenocarcinoma cells transfected with human LGR5 (cells from Dr. Hans Clevers, Hubrecht Institute) were cultured and then harvested using Accutase™ Cell Detachment Solution (Cat. No. 561527). The cells were stained with either BV510 Rat IgG2b, κ Isotype Control (Cat. No. 562951; dashed line histogram) or BV510 Rat Anti-Human Lgr5 (N-Terminal) (Cat. No. 563211; solid line histogram) at matched concentrations. Fluorescence histograms were derived from gated events based on the light-scattering characteristics of viable LS 174T cells. Flow cytometry was performed on a BD LSRFortessa™.

Preparation And Storage

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 with BD Horizon™ BV510 under optimum conditions, and unconjugated antibody and free BD Horizon™ BV510 were removed.

Recommended Assay Procedures

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 Brilliant Stain Buffer (Cat. No. 563794/566349) or the Brilliant Stain Buffer Plus (Cat. No. 566385).

Product Notices

  1. This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
  2. An isotype control should be used at the same concentration as the antibody of interest.
  3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  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.

8F2

Lgr5 (leucine-rich-repeat-containing G-protein-coupled receptor 5)  is a seven transmembrane-domain receptor that is a target gene for Wnt and marks stem cells in the small intestine, colon, stomach, and hair follicle. Lgr5 was initially identified as a potential stem cell marker due to restricted expression of Lgr5 in the intestinal crypt and labeling of rapidly cycling cells of the colon and intestine. Using both lineage tracing and organoid culture experiments, Lgr5 positive cells are capable of generating all types of the small intestine epithelium hence indicating that Lgr5 marks stem cells of the small intestine and colon. R-spondin growth factors, which are secreted agonists of the Wnt pathway, bind Lgr5. The binding of R-spondins to Lgr5 leads to recruitment of the Frizzled/LRP Wnt receptor complex, which binds to Wnt ligands and leads to downstream Wnt signaling. Lgr5 is up-regulated in colon and ovarian cancers and has been implicated in promotion of tumor growth and metastasis.

The 8F2 monoclonal antibody recognizes an epitope in the N-terminal region of Human Lgr5.

The antibody was conjugated to BD Horizon™ BV510 which is part of the BD Horizon™ Brilliant Violet™ family of dyes. With an Ex Max of 405-nm and Em Max at 510-nm, BD Horizon™ BV510 can be excited by the violet laser and detected in the BD Horizon™ V500 (525/50-nm) filter set. BD Horizon™ BV510 conjugates are useful for the detection of dim markers off the violet laser.

BV510
The BD Horizon Brilliant Violet™ 510 (BV510) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology based dye with an excitation maximum (Ex Max) at 327-nm / 405-nm and an emission maximum (Em Max) at 512-nm. BV510, driven by BD innovation, is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 510-nm (e.g., a 525/50 bandpass filter). The dye can be excited by the UV (355-nm) laser resulting in cross-laser excitation and spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
