BUV395 Mouse Anti-Human CD20
BUV395 Mouse Anti-Human CD20
Two-color flow cytometric analysis of CD20 expression on human peripheral blood lymphocytes. Whole blood was stained with APC Mouse Anti-Human CD19 antibody (Cat. No. 555415/561742) and either BD Horizon™ BUV395 Mouse IgG2b, κ Isotype Control (Cat. No. 563558; Left Panel) or BD Horizon™ BUV395 Mouse Anti-Human CD20 antibody (Cat. No. 563781/563782; Right Panel). Erythrocytes were lysed with BD FACS™ Lysing Solution (Cat. No. 349202). Two color flow cytometric dot plots show the correlated expression of CD20 (or Ig Isotype Control staining) versus CD19 derived from gated events with the forward and side light-scatter characteristics of intact lymphocytes. Flow cytometric analysis was performed using a BD™ LSR II Flow Cytometer System.

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 BUV395 under optimum conditions, and unconjugated antibody and free BD Horizon BUV395 were removed.

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. 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.
  4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  5. Species cross-reactivity detected in product development may not have been confirmed on every format and/or application.
  6. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.

2H7

The 2H7 monoclonal antibody specifically binds to CD20, encoded by the MS4A1 (Membrane-spanning 4-domains, subfamily A, member 1) gene. CD20 is a 33-37 kDa, unglycosylated four-transmembrane phosphoprotein. CD20 is expressed on pre-B-cells, resting and activated B cells, and follicular dendritic cells, but not plasma cells. Low level CD20 expression is observed on a small subset of normal circulating T lymphocytes. The CD20 molecule is involved in the regulation of B-cell activation.

The antibody was conjugated to BD Horizon™ BUV395 which has been exclusively developed by BD Biosciences as an optimal dye for use on a 355 nm laser equipped instrument. With an Ex Max at 348 nm  and an Em Max at 395 nm, this dye has virtually no spillover into any other detector. BD Horizon™ BUV395 can be excited with a 355 nm laser and detected with a 379/28 filter.

BUV395
The BD Horizon Brilliant™ Ultraviolet 395 (BUV395) Dye is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This base dye is a polymer fluorochrome with an excitation maximum (Ex Max) of 348-nm and an emission maximum (Em Max) at 395-nm. Driven by BD innovation, BUV395 is designed to be excited by the ultraviolet laser (355-nm) and detected using an optical filter centered near 380-nm (e.g., 379/28-nm bandpass filter). BUV395 is the ideal dye when using only one detector on the ultraviolet laser as it spills into no other detectors and no other fluors spill into it. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
