BD Horizon™ PE-CF594 Mouse Anti-Human HLA-ABC

Name: PE-CF594 Mouse Anti-Human HLA-ABC
Brand: PE-CF594 Mouse Anti-Human HLA-ABC
SKU: 567869

Clone W6/32 (RUO)

Multiparameter flow cytometric analysis of HLA-ABC expression on human peripheral blood leucocyte populations. Whole blood was stained with either BD Horizon™ PE-CF594 Mouse IgG2a, κ Isotype Control (Cat. No. 562306; Left Plot) or BD Horizon™ PE-CF594 Mouse Anti-Human HLA-ABC antibody (Cat. No. 567869/567870; 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 to ensure that BD® CompBeads are appropriate for your specific cellular application.

Product Notices

Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
Please observe the following precautions: Absorption of visible light can significantly alter the energy transfer occurring in any tandem fluorochrome conjugate; therefore, we recommend that special precautions be taken (such as wrapping vials, tubes, or racks in aluminum foil) to prevent exposure of conjugated reagents, including cells stained with those reagents, to room illumination.
Source of all serum proteins is from USDA inspected abattoirs located in the United States.
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.
This reagent has been pre-diluted for use at the recommended Volume per Test. We typically use 1 × 10^6 cells in a 100-µl experimental sample (a test).
For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
An isotype control should be used at the same concentration as the antibody of interest.

Antibody Details

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.

This antibody is conjugated to BD Horizon PE-CF594, which has been developed exclusively by BD Biosciences as a better alternative to PE-Texas Red®. PE-CF594 excites and emits at similar wavelengths to PE-Texas Red® yet exhibits improved brightness and spectral characteristics. Due to PE having maximal absorption peaks at 496 nm and 564 nm, PE-CF594 can be excited by the blue (488-nm), green (532-nm) and yellow-green (561-nm) lasers and can be detected with the same filter set as PE-Texas Red® (eg, 610/20-nm filter).

Format Details

PE-CF594

BD Horizon™ PE-CF594 dye is a part of the BD PE family of dyes. This tandem fluorochrome is comprised of a R-Phycoerythrin (PE) donor that has excitation maxima (Ex Max) of 496-nm and 566-nm and an acceptor dye with an emission maximum (Em Max) at 615-nm. PE-CF594, driven by BD innovation, is designed to be excited by the blue (488-nm), Green (532-nm) and yellow-green (561-nm) lasers and detected using an optical filter centered near 615 nm (e.g., a 610/20-nm bandpass filter). The donor dye can be excited by the Blue (488-nm), Green (532-nm) and yellow-green (561-nm) lasers and the acceptor dye can be excited by the green (532-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.
