The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

アプリケーション Abreviews 特記事項
WB 1/1000 - 1/2000. Detects a band of approximately 50 kDa (predicted molecular weight: 50 kDa).
ICC 1/50 - 1/100.
Flow Cyt 1/20.

ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.

IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
  • 追加情報
    Is unsuitable for IP.
  • ターゲット情報

    • 機能
      May play an important role in CKII- and p60c-src-induced signal transduction cascades.
    • 配列類似性
      Belongs to the protein-tyrosine phosphatase family. Non-receptor class 1 subfamily.
      Contains 1 tyrosine-protein phosphatase domain.
    • 翻訳後修飾
      Oxidized on Cys-215; the Cys-SOH formed in response to redox signaling reacts with the alpha-amido of the following residue to form a 4-amino-3-isothiazolidinone serine cross-link, triggering a conformational change that inhibits substrate binding and activity. The active site can be restored by reduction.

    • ab75856, at 1/50 dilution, staining PTP1B in human tonsil, by Immunohistochemistry using formalin-fixed, paraffin-embedded tissue.


    • Predicted band size : 50 kDa

      Lane 1: Wild-type HAP1 cell lysate (20 µg)
      Lane 2: PTPB1 knockout HAP1 cell lysate (20 µg)
      Lane 3: Jurkat cell lysate (20 µg)
      Lane 4: MCF7 cell lysate (20 µg)
      Lanes 1 - 4: Merged signal (red and green). Green - ab75856 observed at 54 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab75856 was shown to specifically react with PTP1B when PTP1B knockout samples were used. Wild-type and ProteinX knockout samples were subjected to SDS-PAGE. ab75856 and ab8245 (loading control to GAPDH) were diluted 1/1000 and 1/2000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.

    • Flow Cytometry analysis of Jurkat cells labelling PTP1B with ab75856 at 1/2000 (red). Cells were fixed with 90% methanol. ab150077, Alexa Fluor® 488-conjugated goat anti-rabbit IgG (1/2000) was used as the secondary antibody. Black - Isotype control, rabbit monoclonal IgG (ab172730). Blue - Unlabelled control, cells without incubation with primary and secondary antibodies.
