LEFT: Analysis of ZAP70 (pY292) in activated human T lymphocytes.  Human whole blood was either stimulated by cross-linking of CD3 with NA/LE Mouse anti-Human CD3 mAb UCHT1 (Cat. No. 555329) on ice for 15 minutes followed by 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 histogram), or unstimulated (open histogram).  The cells were lysed and fixed with 1X BD Phosflow™ Lyse/Fix Buffer (Cat. No. 558049) for 10-15 minutes at 37ºC, 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® 488 Mouse anti-ZAP70 (pY292) and PerCP-Cy5.5 Mouse anti-human CD3 mAb SK7 (Cat. No. 340949).  Flow cytometry was performed on a BD FACSCalibur™ flow cytometry system.  For data analysis, CD3-positive and -negative lymphocytes were selected by their scatter and staining profiles.  The figure displays the CD3-positive T lymphocytes.  Up-regulated phosphorylation of ZAP70 (pY292) was not observed in the CD3-negative lymphocytes (data not shown).

No. 555329) and NA/LE Mouse anti-Human CD28 mAb CD28.2 (Cat. No. 555725) on ice for 15 minutes followed by 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 histogram), or unstimulated (open histogram).  The cells were fixed (BD Cytofix™ buffer, Cat. No. 554655) for 10 minutes at 37°C, permeabilized (BD Phosflow™ Perm Buffer III, Cat. No. 558050) on ice for at least 30 minutes, blocked with normal mouse immunoglobulin, and then stained with Alexa Fluor® 488 Mouse anti-ZAP70 (pY292).  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® 488 under optimum conditions, and unreacted Alexa Fluor® 488 was removed.

Recommended Assay Procedures

This antibody conjugate is suitable for intracellular staining of human whole blood (using BD Phosflow™ Lyse/Fix Buffer) and peripheral blood mononuclear cells (using BD Cytofix™ Fixation Buffer).  Any of the three BD Phosflow™ permeabilization buffers may be used.

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.

J34-602

The 70-kDa ζ chain-associated protein (ZAP70) is a Syk-family protein tyrosine kinase (PTK) that associates with the ζ subunit of the T cell antigen receptor (TCR) and undergoes tyrosine phosphorylation following TCR stimulation.  ZAP70 contains two SH2-like domains with the PTK domain located at the C-terminus.  TCR-mediated Lck activity leads to phosphorylation of ZAP70 on Tyrosine 493 in the regulatory loop of the PTK domain leading to upregulation of ZAP70 kinase activity.  Tyrosine 292 (Y292), in the linker region between the SH2 and PTK domains, is autophosphorylated by the activated PTK domain.  By binding with c-Cbl, the phosphorylated Y292 can down-regulate TCR signaling.

The J34-602 antibody recognizes ZAP70 phosphorylated at Y292.

Alexa Fluor™ 488
Alexa Fluor™ 488 Dye is part of the BD blue family of dyes. This is a small organic fluorochrome with an excitation maximum (Ex Max) at 494-nm and an emission maximum (Em Max) at 517-nm. Alexa Fluor™ 488 is designed to be excited by the Blue laser (488 nm) and detected using an optical filter centered near 520-nm (e.g., a 530/30-nm bandpass filter). Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
