The CatchPoint SimpleStep ELISA employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. CatchPoint HRP Development Solution containing the Stoplight Red Substrate is added. During incubation, the substrate is catalyzed by HRP generating a fluorescent product. Signal is generated proportionally to the amount of bound analyte and the intensity is measured in a fluorescence plater reader at 530/570/590 nm Excitation/Cutoff/Emission.
Alpha 1 Antitrypsin (SERPINA1) is a serine protease inhibitor found in a variety of biological fluids. While it can inhibit trypsin, chymotrypsin, and plasminogen activator, its main target is elastase. Alpha 1 Antitrypsin plays a critical role in the lung by inhibiting the activity of elastase, produced by neutrophils during inflammatory responses. The aberrant form plays a role in coagulation and insulin induced NO synthesis. Alpha 1 Antitrypsin deficiency results in emphysema and may also result in liver disease.

Alpha 1 Antitrypsin also known as A1AT or alpha-1 proteinase inhibitor is a serine protease inhibitor with a molecular mass of about 52 kDa. This protein mainly expresses in the liver and found in high concentrations in the blood plasma. A1AT protects tissues from enzymes of inflammatory cells especially neutrophil elastase. Its expression level is regulated by the liver making it a significant player in maintaining tissue integrity.
Biological function summary
A1AT regulates protease activity by forming complexes with target enzymes. It specifically inhibits neutrophil elastase a powerful enzyme capable of degrading elastin an important component of connective tissues. A1AT prevents excessive tissue damage during inflammation by maintaining a balance in protease activity within connective tissues across various organs.
Pathways
Alpha 1 Antitrypsin functions within the proteolytic pathways involved in inflammatory response and tissue remodeling. A1AT is closely related to neutrophil elastase in these processes. It interacts with other protease inhibitors like alpha 2-macroglobulin reinforcing its protective role against enzymatic activity that can lead to tissue destruction under pathophysiological conditions.
Alpha 1 Antitrypsin deficiency is a genetic condition that can cause chronic obstructive pulmonary disease (COPD) and liver cirrhosis. Deficient A1AT levels result in unregulated elastase activity leading to lung tissue damage and impaired liver function. Other proteins such as MMP-9 collaborate with elastase in exacerbating tissue damage illustrating how insufficient A1AT can significantly contribute to disease development.
