| Application: | Anti-SI antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige . |
| Biochem/physiol Actions: | SI (Sucrase-isomaltase, α-glucosidase) is mainly involved in the breakdown of dietary starches and sugars into glucose. In carbohydrate digestion, it essentially hydrolyzes the mixture of linear α-1,4- and branched α-1,6-oligosaccharide substrates. HNF (hepatocyte nuclear factor )-1α and HNF-1β suppresses the SI gene expression as well as its activity. Mutations in the SI gene cause SI congenital sucrase-isomaltase deficiency. |

| Features and Benefits: | Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section. Every Prestige Antibody is tested in the following ways: • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues. • Protein array of 364 human recombinant protein fragments. |
| General description: | SI (Sucrase-isomaltase, a-glucosidase) is a small intestinal molecule of the glycoside hydrolase 31 family (GH31) consisting of duplicated catalytic domains, N- and C-terminal and a narrow hydrophobic +1 subsite for substrate specificity. The two domains are connected through the small intestinal brush-border membrane via an O-glycosylated stalk stemming from the N-terminal domain. |
| Immunogen: | Sucrase-isomaltase, intestinal recombinant protein epitope signature tag (PrEST) |
