The Alpha 1-Antichymotrypsin ELISA kits listed below utilize specific antibodies for the plate-based assay of Alpha 1-Antichymotrypsin in various samples. Alpha 1-Antichymotrypsin is another term for the SERPINA3 gene, which encodes the protein, serpin family A member 3 in humans. It has been reported that Alpha 1-Antichymotrypsin plays a role in inflammatory response pathways and the metabolism of lipids, among other functions. Structurally, the SERPINA3 protein is 423 amino acid residues in length and 47.7 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is known to be a secreted protein. In terms of tissue specificity, it is notably expressed in plasma. This protein is known to be O-glycosylated. Other names for this target antigen include AACT, ACT, and GIG24. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
