Detection of Mouse PTEN by Western Blot. Western blot shows lysates of mouse brain tissue. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human/Mouse PTEN Monoclonal Antibody (Catalog # MAB847) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). A specific band was detected for PTEN at approximately 54 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.**For Western blot, we recommend the use of Rabbit Anti-Human/Mouse/Rat PTEN Affinitiy-purified Polyclonal Ab (AF847).

Detection of PTEN in Human U937 cell line by Flow Cytometry. Human U937 histiocytic lymphoma cell line was stained with Mouse Anti-Human/Mouse PTEN Monoclonal Antibody (Catalog # MAB847, filled histogram) or isotype control antibody (MAB002, open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgG F(ab')2Secondary Antibody (F0101B). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (FC005). Staining was performed using our protocol for Staining Intracellular Molecules.

PTEN in Human Liver. PTEN was detected in immersion fixed paraffin-embedded sections of human liver array using Mouse Anti-Human/Mouse PTEN Monoclonal Antibody (Catalog # MAB847) at 25 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Lower panel shows a lack of labeling if primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents.

Detection of PTEN in Human PBMC lymphocytes by Flow Cytometry. Human peripheral blood mononuclear cell lymphocytes were stained with Mouse Anti-Human/Mouse PTEN Monoclonal Antibody (Catalog # MAB847, filled histogram) or isotype control antibody (Catalog # MAB002, open histogram), followed by Phycoerythrin-conjugated Anti-Mouse IgG F(ab')2Secondary Antibody (Catalog # F0102B). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.

Western Blot Shows Human PTEN Specificity by Using Knockout Cell Line. Western blot shows lysates of HeLa human cervical epithelial carcinoma parental cell line and PTEN knockout HeLa cell line (KO). PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human/Mouse PTEN Monoclonal Antibody (Catalog # MAB847) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). A specific band was detected for PTEN at approximately 55 kDa (as indicated) in the parental HeLa cell line, but is not detectable in knockout HeLa cell line. GAPDH (MAB5718) is shown as a loading control. This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Background: PTEN
The tumor suppressor gene PTEN (phosphatase and tensin homolog deleted on chromosome 10), also known as MMAC1 (mutated in multiple advanced cancers 1), encodes a phosphatase that contains the catalytic signature motif (HCxxGxxRS/T) found in all members of the protein tyrosine phosphatase family. In vitro, the recombinant PTEN has both lipid phosphatase and protein phosphatase activities (1, 2). Interestingly, accumulating evidence has shown that the tumor suppressor activity of PTEN relies on its ability to dephosphorylate phosphatidylinositol (3,4,5)-triphosphate specifically at position 3 of the inositol ring (3). This activity reduces the levels of phosphatidylinositol (3,4,5)-triphosphate which is specifically produced from phosphatidylinositol (4,5)-diphosphate by PI 3-kinase upon activation by a variety of stimuli. Therefore, PTEN antagonizes PI 3-kinase-induced downstream signaling events and cellular processes including cell growth, apoptosis and cell motility. In vivo, the importance of PTEN catalytic activity in its tumor suppressor functions is underscored by the fact that the majority of PTEN missense mutations detected in tumor specimens target the phosphatase domain and cause a loss in PTEN phosphatase activity (4).
