      Analysis of SLP-76 (pY128) in human peripheral blood lymphocytes.  Human peripheral blood mononuclear cells were either unstimulated (open histograms) or stimulated by cross-linking with CD3 (Purified NA/LE Mouse anti-Human CD3 mAb, clone UCHT1,Cat. No. 555329) and CD28 (Purified NA/LE Mouse anti-Human CD28, clone CD28.2, Cat. No. 555725) on ice for 15 minutes followed by incubation with the Purified Goat anti-Mouse Ig (Cat. No. 553998) on ice for 15 minutes, and then allowed to undergo phosphorylation at 37°C for 5 minutes (shaded histograms). The cells were fixed (BD Cytofix™ Fixation buffer Cat. No. 554655) for 10 minutes at 37°C, permeabilized (BD Phosflow™ Perm Buffer III, Cat. No. 558050) on ice for 30 minutes, blocked with normal mouse immunoglobulin, and then stained with Alexa Fluor® 647 Mouse anti-SLP-76 (pY128) (Cat. No. 558438) and PerCP-Cy5.5 Mouse anti-human CD3 mAb SK7 (Cat. No. 340949).  The left panel displays the upregulated phosphorylation of SLP-76 in activated CD3-positive T lymphocytes, while the right panel displays the lack of upregulated SLP-76 phosphorylation in CD3-negative non-T cells.  Flow cytometry was performed on a BD FACSCalibur™ flow cytometry 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

      1. 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).
      2. 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.
      3. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
      4. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at www.bdbiosciences.com/colors.
      5. 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.
      6. Alexa Fluor® 647 fluorochrome emission is collected at the same instrument settings as for allophycocyanin (APC).

      SLP-76 (SH2 domain-containing Leukocyte Protein of 76 kDa) is a tyrosine phosphoprotein that is involved in the T cell receptor (TCR)-mediated intracellular signaling pathway.  It may be involved in the signaling pathways of other peripheral blood leukocytes; thymic/splenic cells; and in human T, B, and monocytic cell lines.  SLP-76 consists of several motifs that signify its importance in protein-protein interactions involved in intracellular signaling pathways, such as the SH2 domain in the C-terminus, the three amino-terminus 17-amino acid repeats with conserved tyrosine and acidic residues (DYE(S/P)P), and a proline rich region.  SLP-76 has been shown to associate with Gads, Grb2, PLCγ1, SLAP-130, and Vav, all of which are part of the signaling cascade in T lymphocytes.  An early event in the T cell activation pathway is the phosphorylation, by the Syk-family kinase ZAP-70, of SLP-76 at the three conserved tyrosine motifs, which then mediate interactions with downstream effectors.  The phosphorylated tyrosine 128 (Y128) brings the Rho family guanine nucleotide exchange factor Vav1 and the Nck adapter protein, which binds to p21-activated kinase (PAK1) and Wiskott-Aldrich syndrome protein (WASP), into the activation complex.  Vav1, PAK1, and WASP may mediate TCR-stimulated actin cytoskeletal rearrangement.  

      The J141-688.36.58 monoclonal antibody recognizes the phosphorylated Y128 of activated SLP-76.

      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 670-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.
