General description
Plasminogen activator inhibitor 1 (UniProt: P05121; also known as PAI, PAI-1, Endothelial plasminogen activator inhibitor, Serpin E1) is encoded by the PAI1 (also known as PLANH1, SERPINE1) gene (Gene ID: 5054) in human. PAI-1 is a member of the superfamily of serine-protease inhibitors and serves as a rapid acting inhibitor of tissue-type (tPA) and the urinary-type (uPA) plasminogen activators. It is a single chain glycoprotein that is synthesized with a signal peptide (aa 1-23), which is subsequently cleave off to produce the mature protein. It plays an essential role in fibrinolysis down-regulation and is responsible for the controlled degradation of blood clots. It is also involved in regulation of cell adhesion and spreading. It also plays a pivotal role in various acute and chronic pathophysiological processes, including cardiovascular disease, tissue fibrosis, cancer, and age-related diseases. Higher expression of PAI-1 is observed in the elderly and is also significantly enhanced in a variety of clinical conditions that are typical of the aging process, including obesity, insulin resistance, decreased immune responses, and increased inflammation. The increased expression of PAI-1 in vivo suppresses fibrinolysis that can lead to the pathological fibrin deposition and tissue damage. High PAI-1 plasma levels are consistently found in patients with severe sepsis but also with other acute or chronic inflammatory diseases such as atherosclerosis. Mutations in PAI1 gene are known to cause PAI-1 deficiency, a hematologic disorder characterized by increased bleeding after trauma, injury, or surgery. The bleeding defect is due to increased fibrinolysis of fibrin blood clots. Two isoforms of PAI-1 have been described that are produced by alternative splicing. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, Affinity™, reproducibility, and stability over conventional monoclonals.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected PAI-1 in Human placenta tissue sections.
Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user.
Biochem/physiol Actions
Clone 1C11 is a ZooMAb® rabbit recombinant monoclonal antibody that specifically detects Plasminogen activator inhibitor 1 (PAI-1). It targets an epitope within 16 amino acids from the N-terminal half.
Physical form
Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.
Preparation Note
Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
