Analysis of SHP2 (pY542) in activated human lymphocytes. Peripheral blood mononuclear cells (PBMC, left panel) were either stimulated by cross-linking of CD3 and CD28 with NA/LE Mouse anti-Human CD3 mAb UCHT1 (Cat. 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, then allowed to undergo phosphorylation at 37°C for 1-2 minutes (shaded histogram) or unstimulated (open histogram). The PBMC were then fixed with BD Cytofix™ Fixation Buffer (Cat. No. 554655) for 10 minutes at 37ºC, permeabilized with BD Phosflow™ Perm Buffer III (Cat. No. 558050) on ice for at least 30 minutes, blocked with normal mouse immunoglobulin, and then stained with PE Mouse anti-Human SHP2 (Y542, Cat. No. 560389). For data analysis, lymphocytes were selected by their scatter profile. Flow cytometry was performed on a BD FACSCanto™ II flow cytometry system. The specificity of mAb L99-921 was confirmed by western blot analysis using unconjugated antibody on lysates from mouse and human cells. Lysates from NIH-3T3 cells (middle panel) that had been treated with 200 nM PDGF (Cat. No. 354051) for 30 minutes (right blot) or untreated (left blot) were probed with purified mouse anti-SHP2 (pY542) monoclonal antibody at concentrations of 1.0, 0.25 and 0.063 μg/ml (Lanes 1, 2, and 3, respectively). SHP2 (pY542) is identified as a band of 65-72 kDa in the treated cells. Lysates from PBMC (right panel) that were untreated (lane 1) or stimulated by cross-linking of CD3 and CD28 (lane 2) were probed with 0.5 μg/ml purified mouse anti-SHP2 (pY542) monoclonal antibody. SHP2 (pY542) is identified as a band of 65-72 kDa, with increased intensity in the stimulated cells.

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 with R-PE under optimum conditions, and unconjugated antibody and free PE were removed.
Recommended Assay Procedures
This antibody conjugate is suitable for intracellular staining of cell lines and peripheral blood mononuclear cells using BD Cytofix™ Fixation Buffer. Any of the three BD Phosflow™ permeabilization buffers may be used.
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).
- 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.

Antibody Details
L99-921
SHP2 is a member of the cytosolic class of protein-tyrosine phosphatases (PTPs). SHP2 reportedly contains two SH2 domains, both of which are N-terminal to the PTP catalytic domain. SH2 PTPs are believed to work in conjunction with protein-tyrosine kinases to maintain intracellular protein phosphotyrosine homeostasis and cell cycle progression. The expression of SHP2 has been reported to be highest in brain, heart, and kidney. SHP2 is phosphorylated at two C-terminal tyrosine residues: Y542 and Y580. Phosphorylation of Y542 creates an interaction in the N-terminal SH2 domain and appears to relieve basal inhibition of the PTP, while phosphorylation at Y580 creates an interaction at the C-terminal that stimulates PTP activity.
The L99-921 monoclonal antibody recognizes the phosphorylated Y542 of SHP2 (PTP2C isoform 2). The homologous phosphorylation site in the PTP2Ci splice variant (isoform 1) is Y546. The specificity of this antibody was validated by confirming, using western blot analysis, that RNA-mediated interference (RNAi) of the specific protein was able to down-regulate the expression of SHP2 (pY542).

Format Details
PE
R-Phycoerythrin (PE), is part of the BD family of Phycobiliprotein dyes. This fluorochrome is a multimeric fluorescent phycobiliprotein with excitation maximum (Ex Max) of 496 nm and 566 nm and an emission maximum (Em Max) at 576 nm. PE 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 575 nm (e.g., a 575/26-nm bandpass filter). As PE is excited by multiple lasers, this can result in cross-laser excitation and fluorescence spillover on instruments with various combinations of Blue, Green, and Yellow-Green lasers. Please ensure that your instrument’s configurations (lasers and optical filters) are appropriate for this dye.
