Key elements and design rationale
- Antibody format: Rabbit Polyclonal Rabbit IgG
- Immunogen / epitope context: E.coli-derived rat SERPINA1 recombinant protein (Position: K211-R411). Rat SERPINA1 shares 66% amino acid (aa) sequence identity with human SERPINA1. (reported region: K211-R411).
- Molecular weight context: reported MW: 53 kDa; calculated MW: 46136 MW
- Reactivity: Mouse,Rat
- Applications: IHC, 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
Alpha-1-antiproteinase; Alpha-1-antiproteinase. SERPINA1 is also known as PI, A1A or AAT. The protein encoded by this gene is secreted and is a serine protease inhibitor whose targets include elastase, plasmin, thrombin, trypsin, chymotrypsin, and plasminogen activator. Defects in this gene can cause emphysema or liver disease. Several transcript variants encoding the same protein have been found for this gene. Functional note: Inhibitor of serine proteases. The primary target is elastase, but also has a moderate affinity for plasmin and thrombin. Reported localization: Secreted. Expression/tissue context: Plasma. .
Research relevance and current trends

- Cancer: Researchers commonly examine how SERPINA1 (Alpha-1-antiproteinase) relates to this theme using model systems and orthogonal readouts.
- Cancer Metabolism: Researchers commonly examine how SERPINA1 (Alpha-1-antiproteinase) relates to this theme using model systems and orthogonal readouts.
Common research applications
- Western blotting: compare relative SERPINA1 (Alpha-1-antiproteinase) levels across conditions; band patterns may reflect isoforms and processing.
- IHC/IHC-F: assess spatial distribution of SERPINA1 (Alpha-1-antiproteinase) across tissue regions and cell types using matched controls.
Notes for experimental interpretation
- Specificity notes: No cross reactivity with other proteins.
- Cross-reactivity: No cross-reactivity with other proteins.
- Family / similarity context: Belongs to the semaphorin family.
- 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.
