背景 | Src-Homology 2 domain Phosphatase-1 (SHP-1), also known as Protein Tyrosine Phosphatase 1C (PTP1C), PTPN6, and Hematopoetic Cell Phosphatase (HCPH), is an enzyme that selectively dephosphorylates tyrosine residues in proteins. Spontaneous point mutations in the SHP-1 gene in mice produce the “motheaten” and "motheaten viable” phenotypes that are severely autoimmune and immunodeficient (1). The enzyme is highly expressed in leukocyte cell types (2). SHP-1 has a regulatory region containing two Src homology 2 (SH2) domains that are critical for its binding to ITIM domains in inhibitory immunoreceptors (3). Deletion of the SH2 domains, as in this product, causes a marked increase in phosphatase activity (4). SHP-1 will dephosphorylate a wide variety of proteins, including the EGF receptor (5). A phosphopeptide containing the EGFR (Y992) sequence (R&D Systems, Catalog # ES006) can be used to measure the activity of SHP-1 by detecting the release of phosphate (R&D Systems, Catalog # DY996). |

Detection of Human/Mouse/Rat SHP‑1 by Western Blot. Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line and Nb2-11 rat lymphoma cell line. PVDF membrane was probed with 0.5 µg/mL Goat Anti-Human/Mouse/Rat SHP‑1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1878) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). For additional reference, Recombinant Human Active SHP‑1 aa 205-595 (Catalog # 1878-SH) and Recombinant Human SHP‑2 (Catalog # 1894-SH) (2 ng/lane) were included. A specific band for SHP-1 was detected at approximately 70 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1. | |
Detection of Human SHP‑1 by Simple WesternTM. Simple Western lane view shows lysates of HepG2 human hepatocellular carcinoma cell line, loaded at 0.2 mg/mL. A specific band was detected for SHP‑1 at approximately 65 kDa (as indicated) using 5 µg/mL of Goat Anti-Human/Mouse/Rat SHP‑1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1878) followed by 1:50 dilution of HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system. |
