      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 BV480 under optimum conditions, and unconjugated antibody and free BD Horizon BV480 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 BD Horizon Brilliant Stain Buffer (Cat. No. 563794/566349).

      For Immunofluorescence Applications:

      The use of a mounting reagent (eg, ProLong® Gold) is highly recommended to maximize the photostability of BV480.  For confocal microscopy systems, a 440 nm laser is the optimal excitation source and the recommended emission filter is a 485/20 nm bandpass filter.  

      For epifluorescence microscopes with broad spectrum excitation sources,  the recommended excitation and emission filters are 445/20 nm and 485/20 nm bandpass filters, respectively.  For specific multicolor imaging applications, the exact filter configurations should be optimized by the end user. For additional instrument/filter configuration information, please visit http://www.bdbiosciences.com/research/cellularimaging.

      Product Notices

      1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
      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.
      5. This antibody has been developed for the immunofluorescence imaging application. However, the antibody is routinely QC tested by flow cytometric analysis. Researchers are encouraged to titrate the reagent for optimal performance.

      RA3-6B2

      The RA3-6B2 monoclonal antibody specifically binds to an epitope on the extracellular domain of the transmembrane CD45 glycoprotein which is dependent upon the expression of exon A and specific carbohydrate residues. It is expressed on B lymphocytes at all stages from pro-B through mature and activated B cell, but it is decreased on plasma cells and a subset of memory B cells. The levels of CD45R expression on the B-cell lineage appear to be developmentally regulated. It is also reportedly found on the abnormal T cells involved in the lymphadenopathy of lpr/lpr and gld/gld mutant mice, on lytically active subsets of lymphokine-activated killer cells (NK cells and non-MHC-restricted CTL), on apoptotic T lymphocytes of mice injected with bacterial superantigen, on a population of NK-cell precursors in the bone marrow, and on B-lymphocyte, T-lymphocyte, and macrophage progenitors in fetal liver. The CD45R antigen has been reported not to be on hematopoietic stem cells, naive T lymphocytes, or MHC-restricted CTL. CD45 is a member of the Protein Tyrosine Phosphatase (PTP) family: Its intracellular (COOH-terminal) region contains two PTP catalytic domains, and the extracellular region is highly variable due to alternative splicing of exons 4, 5, and 6 (designated A, B, and C, respectively), plus differing levels of glycosylation. The CD45 isoforms detected in the mouse are cell type-, maturation, and activation state-specific. The CD45 isoforms play complex roles in T-cell and B-cell antigen receptor signal transduction. CD45R is commonly used as a pan B-cell marker; however, CD19 expression, detectable by the rat anti-mouse CD19 antibody (clone 1D3), is reported to be more restricted to the B-cell lineage. The rat anti-mouse CD45R antibody (clone RA3-6B2) has been reported to enhance isotype switching during in vitro B-cell responses and to inhibit in vivo B-cell responses. Cross-reaction of the RA3-6B2 clone with activated human T lymphocytes has also been reportedly observed.

        

      The antibody was conjugated to BD Horizon BV480 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 436-nm and Em Max at 478-nm, BD Horizon BV480 can be excited by the violet laser and detected in the BD Horizon BV510 (525/40-nm) filter set.  BV480 has less spillover into the BV605 detector and, in general, is brighter than BV510.

      BV480
      The BD Horizon Brilliant Violet™ 480 (BV480) Dye is part of the BD Horizon Brilliant Violet™ family of dyes. This polymer-technology fluorochrome has an excitation maximum (Ex Max) of 440-nm and an emission maximum (Em Max) of 479-nm. Driven by BD innovation, BV480 is designed to be excited by the violet laser (405-nm) and detected using an optical filter centered near 480-nm (e.g., a 525/50 bandpass filter). The increased fluorescence intensity of BV480 and narrower emission spectra, make it a good alternative for BV510 or V500. Due to its excitation profile, BV480 will also has less cross-laser excitation with the UV laser, resulting in less spillover into UV channels compared to BV510. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
