  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.

  Immunofluorescent analysis of 4% paraformaldehyde-fixed, 0.1% Triton X-100 permeabilized NIH/3T3 (Mouse embryonic fibroblast cell line) cells labeling PAI1 with Anti-PAI1 antibody [EPR21850-82] ab222754 at 1/100 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) (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).
