Our Abpromise guarantee covers the use of ab127202 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 60 kDa (predicted molecular weight: 48 kDa).|
FunctionAlthough its physiological function is unclear, it can inhibit neutrophil cathepsin G and mast cell chymase, both of which can convert angiotensin-1 to the active angiotensin-2.
Tissue specificityPlasma. Synthesized in the liver. Like the related alpha-1-antitrypsin, its concentration increases in the acute phase of inflammation or infection. Found in the amyloid plaques from the hippocampus of Alzheimer disease brains.
Involvement in diseaseDefects in SERPINA3 may be a cause of chronic obstructive pulmonary disease (COPD) [MIM:107280].
Sequence similaritiesBelongs to the serpin family.
DomainThe reactive center loop (RCL) extends out from the body of the protein and directs binding to the target protease. The protease cleaves the serpin at the reactive site within the RCL, establishing a covalent linkage between the carboxyl group of the serpin reactive site and the serine hydroxyl of the protease. The resulting inactive serpin-protease complex is highly stable.

Predicted band size: 48 kDa
Observed band size: 60 kDa why is the actual band size different from the predicted?
Additional bands at: 40 kDa. We are unsure as to the identity of these extra bands.
Exposure time: 8 minutes
AACT contains a number of potential glycosylation sites (SwissProt) which may explain its migration at a higher molecular weight than predicted.
