Goat anti human PAI-1 antibody recognizes an internal epitope within human plasminogen activator inhibitor 1 (PAI-1), also known as serpin E1. PAI-1 is a 402 amino acid ~45 kDa serine protease inhibitor and the principle inhibitor of tissue plasminogen activator (tPA) and urokinase (uPA)

PAI-1 is present in plasma, platelets and endothelial cells, is expressed at increased levels in various disease states (Kruithof et al. 1988), and has been linked to an increased occurrence of thrombosis in obesity and coronary artery disease (Oseroff et al. 1989). Defects in PAI-1 are characterized by abnormal bleeding (Takahashi et al. 1996).

Goat anti human PAI-1 antibody has been used successfully for the detection of PAI-1 in human tissues by immunohistochemistry, western blotting and ELISA.

Storage Information

This product is shipped at ambient temperature. It is recommended to aliquot and store at -20°C on receipt. When thawed, aliquot the sample as needed. Keep aliquots at 2-8°C for short term use (up to 4 weeks) and store the remaining aliquots at -20°C.

Avoid repeated freezing and thawing as this may denature the antibody. Storage in frost-free freezers is not recommended.

Application Name Verified Min Dilution Max Dilution
ELISA 1/32000
Immunohistology - Paraffin 1 4.0 6.0 ug/ml
Western Blotting 0.1 0.3 ug/ml
  1. 1 This antibody requires heat-mediated antigen retrieval prior to staining paraffin sections. Citrate buffer pH6.0 is recommended for this purpose.
Where this antibody has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. It is recommended that the user titrates the antibody for use in their own system using appropriate negative/positive controls.
Histology Positive Control Tissue
Human Placenta
Western Blotting
Goat anti human PAI-1 detects a band of approximately 45kDa in human duodenum, liver and lung lysates. A minimum incubation time of 1 hour is recommended with this antibody.
