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 BUV496 under optimal conditions that minimize unconjugated dye and antibody.

Recommended Assay Procedures

For optimal and reproducible results, BD Horizon Brilliant Stain Buffer should be used anytime two or more BD Horizon Brilliant dyes (including BD OptiBuild Brilliant reagents) 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).

Product Notices

  1. This antibody was developed for use in flow cytometry.
  2. 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.
  3. Researchers should determine the optimal concentration of this reagent for their individual applications.
  4. An isotype control should be used at the same concentration as the antibody of interest.
  5. 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.

4E5

The 4E5 monoclonal antibody specifically recognizes Ly-49D, which is expressed on subsets of natural killer (NK) cells in C57BL/6, C3H/He (at a very low frequency), and SJL, but not DBA/2, AKR, CBA/J, or BALB/c mice. Unlike Ly-49D antigen has not been betected on NK-1.1+ (or DX5+) T cells. In 129/J mice, the 4E5 antibody cross-reacts with Ly-49O, Ly-49R, and Ly-49V. The Ly-49 family of NK-cell receptors, members of the C-type lectin superfamily, are disulfide-linked type-II transmembrane protein homodimers with extracellular carbohydrate-recognition domains, which bind to MHC class I alloantigens. The Ly-49 family members are expressed independently, such that an individual NK or T cell may display more than one class of Ly-49 receptor homodimers. Ly-49D weakly binds to MHC class I antigens of the k halpotype, and Ly-49D+ IL-2-activated NK cells lyse target cells expressing H-2[a], H-2[b], H-2[d], H-2[k], H-2[p], H-2[q], and H-2[s] and the CHO (Chinese hamster ovary) cell line. Ly-49D+ cells mediate allogenic resistance to H-2d bone marrow transplantation. In vitro studies suggest that the Ly-49D receptor mediates activation of NK-cell cytolytic activity via tyrosine phosphorylation of their ITIMs (Immunoreceptor Tyrosine-based Inhibitory Motifs). Molecular differences between the Ly-49D stimulatory receptor and the inhibitory members of the Ly-49 family include the absence of an ITIM in Ly-49D, the lack of phosphorylation of Ly-49D in activated NK cells, and the association of a novel tyrosine-phosphorylated protein (pp16) with Ly-49D in activated NK cells. Ly-49O and Ly-49V are closely related to Ly-49A[B6] and, like Ly-49A, have ITIM domains. Ly-49O- and Ly-49V-transfected 293T (human kidney epithelial) cells bind tetramers of H-2D[b], D[b], D[k], and L[d]. In addition, the Ly-49V-transfected cells also bind K[b], K[d], and K[k]. Ly-49R is closely related to Ly-49D[B6] and is putative activating receptor due to its  lack of an ITIM domain. Ly-49R-transfected 293T cells bind soluble tetramers of H-2D[b], D[d], D[k], and L[d].

The antibody was conjugated to BD Horizon™ BUV496 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome of BD Horizon BUV395 with an Ex Max of 348-nm and an acceptor dye with an Em Max at 496-nm. BD Horizon BUV496 can be excited by the ultraviolet laser (355 nm) and detected with a 515/30 nm filter with a 450LP. Due to the excitation of the acceptor dye by other laser lines, there may be significant spillover into the channel detecting BD Horizon V500 or BV510 (eg, 525/40-nm filter). However, the spillover can be corrected through compensation as with any other dye combination.

BUV496
The BD Horizon Brilliant™ Ultraviolet 496 (BUV496) 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 496-nm. BUV496, driven by BD innovation, is designed to be excited by the ultraviolet laser (355-nm) and detected using an optical filter centered near 500-nm (e.g., 515/30-nm bandpass filter). The acceptor dye can be excited by the Violet (405-nm) 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.
