BUV395 Mouse Anti-Human KIR2DL1/S1/S3/S5 (CD158)
Multiparameter flow cytometric analysis of KIR2DL1/S1/S3/S5 (CD158) expression on peripheral blood leucocyte populations. Whole blood was stained with BD Horizon™ BV421 Mouse Anti-Human CD56 antibody (Cat. No. 562751/562752; Lower Plots) and either BD Horizon™ BUV395 Mouse IgG2b, κ Isotype Control (Cat. No. 563558; Left Plots) or BD Horizon™ BUV395 Mouse Anti-Human KIR2DL1/S1/S3/S5 (CD158) (Cat. No. 567326/567327; Right Plots). Erythrocytes were lysed with BD Pharm Lyse™ Lysing Buffer (Cat. No. 555899). Flow cytometry and data analysis were performed using a BD LSRFortessa™ X-20 Cell Analyzer System and FlowJo™ software. Upper Plots: The bivariate pseudocolor density plots showing the correlated expression of KIR2DL1/S1/S3/S5 (CD158) [or Ig isotype control staining] versus side light scatter signals (SSC-A) were derived from gated events with the forward and side-light scatter characteristics of intact leucocytes. Lower Plots: The bivariate pseudocolor density plots showing the correlated expression of KIR2DL1/S1/S3/S5 (CD158) [or Ig isotype control staining] versus CD56 were derived from gated events with the forward and side-light scatter characteristics of intact lymphocytes.

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 and unconjugated antibody and free dye were removed.

Recommended Assay Procedures

BD™ CompBeads can be used as surrogates to assess fluorescence spillover (Compensation).  When fluorochrome conjugated antibodies are bound to 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 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 BD Horizon Brilliant™ dyes are used in a multicolor flow cytometry panel.  Fluorescent dye interactions may cause staining artifacts which may affect data interpretation.  The BD Horizon Brilliant™ Stain Buffer was designed to minimize these interactions. When BD Horizon Brilliant™ Stain Buffer is used in in the multicolor panel, it should also be used in the corresponding compensation controls for all dyes to achieve the most accurate compensation. For the most accurate compensation, compensation controls created with either cells or beads should be exposed to BD Horizon Brilliant™ Stain Buffer for the same length of time as the corresponding multicolor panel. 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).

HP-MA4

The HP-MA4 monoclonal antibody specifically recognizes several Killer Cell Immunoglobulin-like Receptors (KIRs) which are also known as CD158 molecules. HP-MA4 recognizes Killer cell immunoglobulin-like receptor 2DL1 (encoded by KIR2DL1; aka, CD158a and NKAT-1), Killer cell immunoglobulin-like receptor 2DS1 (KIR2DS1; CD158h), Killer cell immunoglobulin-like receptor 2DS3 (KIR2DS3; NKAT-7), and Killer cell immunoglobulin-like receptor 2DS5 (KIR2DS5; CD158g, NKAT-9) which are collectively known as KIR2DL1/S1/S3/S5 (CD158). These type I transmembrane glycoproteins are encoded by polymorphic genes and have 2 extracellular Ig-like domains (KIR2D, domains D1 and D2) followed by a transmembrane region and either long (L) or short (S) cytoplasmic domains. Various CD158 molecules are differentially expressed by CD56dim natural killer (NK) cells and some T cells and can regulate their cytotoxic effector functions. Although different KIR gene content varies amongst haplotypes for individuals, certain "framework" genes including KIR3DL3, KIR3DP1, KIR3DL4, and KIR3DL2, are found in all haplotypes. KIR2DL1 has a long cytoplasmic domain with two tyrosine-based inhibitory motifs (ITIM) that enables inhibitory signal transduction by ligand-bound KIR2DL1 leading to reduced cytotoxic effector cell activity. KIR2DS1, KIR2DS3, KIR2DS5 (KIR2DS1/S3/S5) proteins each have a short cytoplasmic tail with a positively charged amino acid in their transmembrane region which allows association with the DAP12 transmembrane protein. DAP12 acts as an activating signal transduction element through its immunoreceptor tyrosine-based activation motifs (ITAMs) in its cytoplasmic domain leading to upregulated cytotoxic effector cell function. Some MHC class I molecules can serve as ligands for CD158 molecules, with HLA-C ligands reported for KIR2DL1, KIR2DS1, and KIR2DS5.

The antibody was conjugated to BD Horizon™ BUV395 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. With an Ex Max near 348 nm and an Em Max near 395 nm, BD Horizon™ BUV395 can be excited by the ultraviolet laser (355 nm) laser and detected with a 379/28 filter. This dye has been exclusively developed by BD Biosciences as an optimal dye for use on instruments equipped with the ultraviolet laser and has virtually no spillover into any other detector.

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.
