Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: E. coli-derived rat PAI1 recombinant protein (Position: S24-D240). (reported region: S24-D240).
- Molecular weight context: reported MW: 45-50 kDa; calculated MW: nan
- Reactivity: Mouse,Rat
- Applications: ELISA, WB
As a polyclonal antibody, the reagent recognizes multiple epitopes on the target, which can improve detection robustness but may increase sensitivity to sample-dependent epitope changes.
Biological background
serpin family E member 1. Plasminogen activator inhibitor-1 (PAI-1) also known as endothelial plasminogen activator inhibitoror serpin E1 is a protein that in humans is encoded by the SERPINE1 gene. This gene encodes a member of the serine proteinase inhibitor (serpin) superfamily. This member is the principal inhibitor of tissue plasminogen activator (tPA) and urokinase (uPA), and hence is an inhibitor of fibrinolysis. Defects in this gene are the cause of plasminogen activator inhibitor-1 deficiency (PAI-1 deficiency), and high concentrations of the gene product are associated with thrombophilia. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. Functional note: Serine protease inhibitor. This inhibitor acts as 'bait' for tissue plasminogen activator, urokinase, protein C and matriptase-3/TMPRSS7. Its rapid interaction with PLAT may function as a major control point in the regulation of fibrinolysis (By similarity). Reported localization: Secreted. Expression/tissue context: Ubiquitous.
Research relevance and current trends
- Angiogenesis: Researchers commonly examine how Serpine1 relates to this theme using model systems and orthogonal readouts.
- Cardiovascular: Researchers commonly examine how Serpine1 relates to this theme using model systems and orthogonal readouts.
Common research applications
- Western blotting: compare relative Serpine1 levels across conditions; band patterns may reflect isoforms and processing.
- ELISA-compatible use: when applicable, interpret signal as relative abundance across sample sets with consistent handling and dilution strategy.
Notes for experimental interpretation
- Specificity notes: No cross reactivity with other proteins.
- Cross-reactivity: No cross-reactivity with other proteins.
- Isoforms and PTMs: Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.
- Controls: Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD/KO samples when available.
