ab242674 is a BSA and Azide Free antibody supplied in an unconjugated format and it is suitable for sandwich ELISAs to quantify Human Alpha 1-antichymotrypsin. The recommended pair for sandwich ELISA is:
Capture: ab242674, Human Alpha 1-antichymotrypsin Capture Antibody (unconjugated)
Detector: Anti-AACT antibody [EPR20127-181] - BSA and Azide free (Detector) ab242919, Human Alpha 1-antichymotrypsin Detector Antibody (unconjugated)
The reference range value is 500 - 32000 pg/ml.
Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.
This product is a recombinant monoclonal antibody, which offers several advantages including:
- - High batch-to-batch consistency and reproducibility
- - Improved sensitivity and specificity
- - Long-term security of supply
- - Animal-free batch production
For more information, read more on recombinant antibodies.
Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.
This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.
Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
The recommended antibody orientation is based on internal optimization for ELISA-based assays. Antibody orientation is assay dependent and needs to be optimized for each assay type. Please note that the range provided for this antibody is only an estimation based on the performance of the product using the recommended antibody pair. Performance of the antibody pair will depend on the specific characteristics of your assay. We guarantee the product works in sandwich ELISA, but we do not guarantee the sensitivity or dynamic range of the antibody in your assay.
Supplementary info
- This supplementary information is collated from multiple sources and compiled automatically.
- Activity summary
The target protein Alpha-1-antichymotrypsin (AACT) also known as ACT is a serpin family member with a mass of approximately 68 kDa. This protein functions as an inhibitor of serine proteases particularly targeting chymotrypsin-like enzymes. AACT is expressed in the liver and secreted into the plasma where it carries out its inhibitory role. It is a significant component of the antiprotease shield in human physiology guarding tissues against proteolytic damage.
- Biological function summary
Alpha-1-antichymotrypsin plays a role in regulating protease activity to maintain tissue integrity. AACT forms part of a complex that involves other protease inhibitors and enzymes contributing to the balance of protein breakdown and regeneration. Its presence in the extracellular matrix highlights its structural and protective functions supporting cells against enzyme-mediated degradation.
- Pathways
Alpha-1-antichymotrypsin takes part in inflammatory and immune response pathways. It interacts within the acute phase response pathway a system activated during inflammatory events. This protein's relationship with other protease inhibitors such as alpha-1-antitrypsin accentuates its role in controlling proteolytic enzymes that could otherwise propagate unchecked inflammation and tissue damage.
- Associated diseases and disorders
Alpha-1-antichymotrypsin associates with neurodegenerative diseases such as Alzheimer's disease and pulmonary disorders. Its elevated levels have been observed in Alzheimer's disease cases where it might participate alongside amyloid-beta precursor protein influencing amyloid plaque formation. In lung-related disorders its collaboration with proteins like elastase can affect tissue breakdown emphasizing its role in maintaining pulmonary health.
