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 to the dye under optimum conditions that minimize unconjugated dye and antibody.

推奨アッセイ手順

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 CompBead 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 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).

Note:  When using high concentrations of antibody, background binding of this dye to erythroid cell subsets (mature erythrocytes and precursors) has been observed.  For researchers studying these cell populations, or in cases where light scatter gating does not adequately exclude these cells from the analysis, this background may be an important factor to consider when selecting reagents for panel(s).

Product Notices

  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.

L203.rMAb

The L203.rMab is a recombinant monoclonal antibody that was derived from L203 hybridoma cells. The L203.rMab specifically recognizes a monomorphic epitope on the extracellular region of human HLA-DR antigens which are human Major Histocompatibility Complex (MHC) Class II antigens. HLA-DR antigens are heterodimers comprised of two different type I transmembrane glycoproteins that are noncovalently-associated. The ~34 kDa HLA-DR alpha (HLA-DRα) chain is encoded by HLA-DRA whereas the ~28 kDa HLA-DR beta (HLA-DRβ) chains are encoded by one of the 4 different HLA-DRB loci (HLA-DRB1,3,4,5) that are located within the Human Leukocyte Antigen (HLA) Complex of chromosome 6. Each chain is comprised of an extracellular region with an IgSF domain, followed by a transmembrane sequence and a short cytoplasmic tail. The L203.rMab antibody recognizes a common determinant that is dependent on the association of HLA-DR alpha and beta chains. HLA-DR is variably expressed on B cells, activated T cells and NK cells, monocytes, macrophages, dendritic cells (DC), Langerhans cells, thymic epithelial cells, and tumor cell lines including B cell lines, myelomas, and some myeloid leukemias. HLA-DR functions in the presentation of peptide antigens to CD4+ T lymphocytes in the generation and regulation of adaptive immune responses. HLA-DR expressed on thymic stromal cells plays a key role in the positive and negative selection of CD4+ T cells during thymopoiesis. Certain HLA-DR alleles, polymorphisms or aberrant expression patterns are associated with susceptibility to diseases including autoimmunity and cancer. L203 antibody binding is reportedly blocked by the L243 monoclonal antibody suggesting that the two antibodies recognize crossreactive or spatially related determinants on HLA-DR.

The antibody was conjugated to BD Horizon BUV737 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome with an Ex Max near 350 nm and an Em Max near 737 nm. BD Horizon Brilliant BUV737 can be excited by the ultraviolet laser (355 nm) and detected with a 740/35 nm filter.  Due to the excitation of the acceptor dye by the red laser line, there may be significant spillover into red laser detectors with filters in the 700-720 nm range.

BUV737
The BD Horizon Brilliant™ Ultraviolet 737 (BUV737) Dye is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This tandem fluorochrome is comprised of a BUV395 donor with an excitation maximum (Ex Max) of 350-nm and an acceptor dye with an emission maximum (Em Max) at 735-nm. BUV737, driven by BD innovation, is designed to be excited by the ultraviolet laser (355-nm) and detected using an optical filter centered near 740-nm (e.g., 740/35 bandpass filter). The acceptor dye can be excited by the Red (628–640nm) laser resulting in cross-laser excitation and fluorescence spillover. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
