PTP-MEG2/PTPN9 Antibody (291835) [Unconjugated]

Western blot shows lysates of Raji human Burkitt's lymphoma cell line, TS1 mouse helper T cell line, CTLL‑2 mouse cytotoxic T cell line, and Nb2‑11 rat lymphoma cell line. PVDF membrane was probed with 1 µg/mL of Human/Mouse/Rat PTP-MEG2 Monoclonal Antibody (Catalog # MAB2668) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for PTP-MEG2 at approximately 68 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background

Megakaryocyte protein tyrosine phosphatase 2 (PTP-MEG2), also known as PTPN9, contains an N-terminal domain homologous to the yeast retinaldehyde binding domain Sec14p and a C-terminal phosphatase domain. The Sec14p domain targets PTP-MEG2 to the membrane of secretory vesicles, where it promotes vesicle fusion. Elevated levels of membrane-bound PTP-MEG2 activity in erythroid progenitor cells are observed in polycythemia vera and may affect responsiveness to colony stimulating factors.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Primary Antibodies are guaranteed for 1 year from date of receipt.
