Alexa Fluor™ 647 Mouse Anti-Human HLA-ABC
Alexa Fluor™ 647 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 Alexa Fluor® 647 Mouse IgG2a, κ Isotype Control (Cat. No. 565357; Left Plot) or Alexa Fluor® 647 Mouse Anti-Human HLA-ABC antibody (Cat. No. 567855/567856; 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 unreacted dye was removed.

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® CompBeads. This will ensure that BD® CompBeads are appropriate for your specific cellular application.

Product Notices

  1. Please refer to www.bdbiosciences.com/us/s/resources for technical protocols.
  2. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
  3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
  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.
  5. 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).
  6. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
  7. An isotype control should be used at the same concentration as the antibody of interest.

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.

Alexa Fluor™ 647
Alexa Fluor™ 647 Dye is part of the BD red family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 653-nm and an emission maximum (Em Max) at 669-nm. Alexa Fluor 647 is designed to be excited by the Red laser (627-640 nm) and detected using an optical filter centered near 520-nm (e.g., a 660/20 nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
