Principle of the Assay: AGLU ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-AGLU antibody and an AGLU-HRP conjugate. The assay sample and buffer are incubated together with AGLU-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the AGLU concentration since AGLU from samples and AGLU-HRP conjugate compete for the anti-AGLU antibody binding site. Since the number of sites is limited, as more sites are occupied by AGLU from the sample, fewer sites are left to bind AGLU-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The AGLU concentration in each sample is interpolated from this standard curve.
NCBI and Uniprot Product Information
NCBI Description
This gene encodes acid alpha-glucosidase, which is essential for the degradation of glycogen to glucose in lysosomes. Different forms of acid alpha-glucosidase are obtained by proteolytic processing. Defects in this gene are the cause of glycogen storage disease II, also known as Pompe's disease, which is an autosomal recessive disorder with a broad clinical spectrum. Three transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]
Uniprot Description
GAA: Essential for the degradation of glygogen to glucose in lysosomes. Defects in GAA are the cause of glycogen storage disease type 2 (GSD2); also called acid alpha-glucosidase (GAA) deficiency or acid maltase deficiency (AMD). GSD2 is a metabolic disorder with a broad clinical spectrum. The severe infantile form, or Pompe disease, presents at birth with massive accumulation of glycogen in muscle, heart and liver. Cardiomyopathy and muscular hypotonia are the cardinal features of this form whose life expectancy is less than two years. The juvenile and adult forms present as limb-girdle muscular dystrophy beginning in the lower limbs. Final outcome depends on respiratory muscle failure. Patients with the adult form can be free of clinical symptoms for most of their life but finally develop a slowly progressive myopathy. Belongs to the glycosyl hydrolase 31 family.

Product Notes
The Monkey A-Glu gaa (Catalog #AAA744987) is an ELISA Kit and is intended for research purposes only. The product is available for immediate purchase. The AAA744987 ELISA Kit recognizes Monkey A-Glu. It is sometimes possible for the material contained within the vial of "alpha-Glucosidase, ELISA Kit" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
