Detection of Mouse Phospho-SHP‑2 (Y542) by Western Blot. Western blot shows lysates of NIH-3T3 mouse embryonic fibroblast cell line untreated (-) or treated (+) with 50 ng/mL Human PDGF-BB (Catalog # 220-BB) for 20 minutes. PVDF membrane was probed with 1 µg/mL of Rabbit Anti-Human/Mouse Phospho-SHP-2 (Y542) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3790), followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Phospho-SHP-2 (Y542) at approximately 72 kDa (as indicated). The lysates were also probed for total SHP-2 with Human/Mouse/Rat SHP-2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1894). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Detection of Mouse Phospho-SHP‑2 (Y542) by Simple WesternTM. Simple Western lane view shows lysates of NIH-3T3 mouse embryonic fibroblast cell line untreated (-) or treated (+) with 50 ng/mL Recombinant Human PDGF-BB (Catalog # 220-BB) for 20 minutes, loaded at 0.2 mg/mL. A specific band was detected for Phospho-SHP-2 (Y542) at approximately 72 kDa (as indicated) using 10 µg/mL of Rabbit Anti-Human/Mouse Phospho-SHP-2 (Y542) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3790). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.*Non-specific interaction with the 230 kDa Simple Western standard may be seen with this antibody.

SHP‑2 in THP‑1 Human Cell Line. SHP‑2 was detected in immersion fixed THP‑1 human acute monocytic leukemia cell line treated with PMA(positive staining) and THP‑1 human acute monocytic leukemia cell line (untreated; negative staining) using Rabbit Anti-Human/Mouse Phospho-SHP‑2 (Y542) Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3790) at 3 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Rabbit IgG Secondary Antibody (red; NL004) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm. Staining was performed using our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Background: SHP-2
Src-Homology domain-2 containing protein tyrosine Phosphatase 2 (SHP-2), also called protein tyrosine phosphatase, non-receptor type 11 (PTPN11), PTP1D, PTP2C, and SYP, is an enzyme that dephosphorylates tyrosine residues in proteins. The protein contains two Src homology 2 (SH2) domains, which both regulate the activity of the enzyme (1) and allow it to selectively bind to SH2 sites on proteins such as Dok1, IRS1, and the insulin receptor (2). SHP-2 plays a unique stimulatory role in cell signaling. Cells lacking SHP-2 have poor mobility because the hyper-phosphorylation of FAK and other proteins in the focal adhesion complex (3) prevents turnover of cellular attachment points. Without SHP-2, sustained ERK stimulation does not take place (4). The Y992 phosphorylation site of EGFR is a particularly good substrate for SHP-2 (5) and a phosphopeptide containing this sequence can be used to measure the activity of the enzyme (R&D Systems, Catalog # ES006) by detecting release of phosphate (R&D Systems, Catalog # DY996).
