    PAI1 was immunoprecipitated from 0.35 mg HepG2 (human hepatocellular carcinoma epithelial cell line) whole cell lysate with ab222754 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab222754 at 1/1,000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/5,000 dilution.
    Lane 1: HepG2 whole cell lysate 10 µg (Input).
    Lane 2: ab222754 IP in HepG2 whole cell lysate (+).
    Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab222754 in HepG2 whole cell lysate (-).
    Blocking/Dilution buffer: 5% NFDM/TBST.
    Exposure time: 3 minutes.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab222754).

    Flow cytometric analysis of 4% paraformaldehyde-fixed, 90% methanol permeabilized NIH/3T3 cells serum-starved for 4 hours, treated with TGF-β (10 ng/ml) for 3 hours, and then with TGF-β (10 ng/ml) and BFA (300 ng/ml) together for 18 hours (Red) / Untreated control (Green) labeling PAI1 with ab222754 at 1/60 (red/green) compared with a Rabbit monoclonal IgG (ab172730) (black) and an unlabeled control (cells without incubation with primary antibody and secondary antibody) (blue). Goat anti rabbit IgG (Alexa Fluor® 488, ab150077), at 1/2000 dilution was used as the secondary antibody.

    The expression of PAI-1 is induced by TGF-β in NIH/3T3 cell line (PMID 17890327).

    Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized NIH/3T3 (Mouse embryonic fibroblast cell line) cells labeling PAI1 with ab222754 at 1/100 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1,000 dilution (green). Confocal image showing the signal is increased in 4 hour serum-starved NIH/3T3 cells treated with TGF-β (10 ng/ml) for 3 hours, then with TGF-β (10 ng/ml) and BFA (300 ng/ml) together for 18 hours. The expression of PAI-1 is induced by TGF-β in the NIH/3T3 cell line (PMID 17890327). The nuclear counter stain is DAPI (blue).
    Counterstained with ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) at a 1/200 dilution (red).
    The negative control is the secondary antibody only.

    Additional bands at: 37 kDa (possible non-specific binding)

    Blocking/Diluting buffer and concentration: 5% NFDM/TBST.

    The expression levels of mouse and rat PAI1 may be low in normal liver tissue (PMID: 21898503). This antibody detects a 37 kDa extra band and no specific band in mouse liver and no bands in rat liver.
    Although lung tissue is reported to be PAI1 positive (PMID: 21768189, PMID: 17032919), this antibody can’t detect band of target in mouse lung and detects weak target band in rat lung.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab179483).
