Flow cytometric analysis of HLA-DQ expression on human peripheral blood lymphocytes and monocytes. Human whole blood was stained with either Alexa Fluor® 647 Mouse IgG2a, κ Isotype Control (Cat. No. 557715; dashed line histograms) or Alexa Fluor® 647 Mouse Anti-Human HLA-DR antibody (Cat. No . 564806; solid line histograms). The erythrocytes were lysed with BD FACS™ Lysing Solution (Cat. No. 349202). The fluorescence histograms showing HLA-DQ expression (or Ig Isotype control staining) were derived from gated events with the forward and side light-scatter characteristics of either intact lymphocytes (Left Panel) or monocytes (Right Panel). Flow cytometric analysis was performed using a BD™ LSR II Flow Cytometer System.

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 Alexa Fluor® 647 under optimum conditions, and unreacted Alexa Fluor® 647 was removed.
Product Notices
- 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).
- An isotype control should be used at the same concentration as the antibody of interest.
- 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.
- Source of all serum proteins is from USDA inspected abattoirs located in the United States.
- The Alexa Fluor®, Pacific Blue™, and Cascade Blue® dye antibody conjugates in this product are sold under license from Molecular Probes, Inc. for research use only, excluding use in combination with microarrays, or as analyte specific reagents. The Alexa Fluor® dyes (except for Alexa Fluor® 430), Pacific Blue™ dye, and Cascade Blue® dye are covered by pending and issued patents.
- Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).
- Alexa Fluor® is a registered trademark of Molecular Probes, Inc., Eugene, OR.

Antibody Details
Tu169
The TU169 monoclonal antibody specifically binds to the human Major Histocompatibility Complex (MHC) Class II HLA-DQ1 and DQ2 antigens and weakly to HLA-DQ3. HLA-DQ antigens exits as heterodimers comprised of polymorphic transmembrane HLA-DQ alpha and beta glycoproteins. HLA-DQ is expressed primarily on B cells, monocytes, macrophages, dendritic cells and activated T lymphocytes. HLA-DQ is involved in presenting peptidic antigens to CD4+ T lymphocytes. This antibody does not cross-react with HLA-DR2 and HLA-DR7. This antibody fixes complement.

Format Details
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.
