Congenital sucrase-isomaltase deficiency is an example of a disease in which mutation results in transport-incompetent molecules. sucrase-isomaltase is not transported to the brush border membrane but accumulates as a mannose-rich precursor in the endoplasmic reticulum, ER-Golgi intermediate compartment, and the cis-Golgi, where it is finally degraded.The enzyme consists of 2 subunits which are synthesized as a single chain mannose-rich precursor. From studies of the cDNA, the human protein has 83% identity with the rabbit enzyme. In addition to the previously reported homology with lysosomal alpha-glucosidase, the sucrase and isomaltase subunits appear to be homologous to a yeast glucoamylase.
Human Sucrase-isomaltase, intestinal (SI) ELISA Kit employs a two-site sandwich ELISA to quantitate SI in samples. An antibody specific for SI has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anySI present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for SI is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of SI bound in the initial step. The color development is stopped and the intensity of the color is measured.
