BUV395 Mouse Anti-Human HLA-ABC
BUV395 Mouse Anti-Human HLA-ABC
Multiparameter flow cytometric analysis of HLA-ABC expression on human peripheral blood leucocyte populations. Whole blood was stained with either BD Horizon™ BUV395 Mouse IgG2a, κ Isotype Control (Cat. No. 563809; Left Plot) or BD Horizon™ BUV395 Mouse Anti-Human HLA-ABC antibody (Cat. No. 567859/567860; Right Plot). Erythrocytes were lysed with BD FACS Lysing Solution (Cat. No. 349202). A bivariate pseudocolor density plot showing the correlated expression of HLA-ABC (or Ig Isotype control staining) versus side-light scatter (SSC-A) signals was derived from gated events with the forward- and side-light scatter characteristics of intact leucocyte populations. Flow cytometry and data analysis were performed using a BD LSRFortessa™ Cell Analyzer System and FlowJo™ software.

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 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® CompBeads. This will 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. /566349) or the BD Horizon Brilliant™ Stain Buffer Plus (Cat. No. 566385).

W6/32

The W6/32 monoclonal antibody recognizes a monomorphic epitope expressed on native β2 microglobulin (β2m)-associated Major Histocompatibility Complex (MHC) class I molecules: Human Leucocyte Antigen (HLA)-A, HLA-B, and HLA-C (HLA-ABC). HLA class I molecules are heterodimers comprised of an ~40-45 kDa, highly polymorphic transmembrane α heavy chain, a type I glycoprotein that is noncovalently-associated with an invariant β2-microglobulin (β2m) light chain. The N-terminal extracellular region of the HLA class I heavy chain is comprised of three domains (α1, α2, and α3). The α1 and α2 domains form a closed antigen-binding groove that accommodates 8-10 aa-peptide antigens. β2m non-covalently associates with the α3 heavy chain domain and promotes HLA class I stability. The W6/32 antibody recognizes a conformational epitope on the HLA class I heavy chain. HLA Class I antigens are normally expressed on most nucleated cells. Their expression is upregulated on activated cells or cells responding to various agents including proinflammatory cytokines or mediators. Reduced HLA Class I expression is found on certain virus-infected or tumor cells. HLA class I antigens expressed on thymic epithelial cells are involved in the positive and negative selection of CD8+ T cell precursors which determines their TCR repertoire during T cell maturation. In the periphery, these HLA Class I antigens serve to either present endogenous antigens or cross-present exogenous antigens for the generation of effector and memory CD8+ T cell responses. Target cell HLA Class I antigens can serve as ligands for inhibitory receptors expressed on NK cells and CD8+ T cells and suppress their cytotoxic responses. Human HLA class I molecules play critical roles in cell-mediated immune responses and tumor surveillance as well as tolerance to self-antigens.

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.
