Number of Assays	Cost
96T	$625
2 x 96T	$1170

Methods Overview:

The included ELISA micro-strip plate is provided pre-coated with an a monoclonal capture antibody selective to the antigen. Samples are mixed by the experimenter with a provided biotin-linked detection antibody and a streptavidin-HRP solution, and then the mixture is added to the plate for 60 min at 37^oC. The plate is washed after the 60 min incubation period and color reagents are added, resulting in a reaction that yields a blue colored solution. A stop solution is applied to terminate the reaction, and the resulting yellow solution is measured at 450nm.

Introduction to Insulin Degrading Enzyme:

Insulin-degrading enzyme (IDE) is a zinc-binding protease known to cleave short polypeptides with variable sequences. IDE was first identifiable for its ability to degrade the B chain of insulin and has since been shown to have additional substrates, including the signaling peptides glucagon, TGF alpha, β-endorphin and amyloid-beta (Aβ). In vitro and in vivo studies have shown correlations between IDE activity levels, Aβ degradation, and Alzheimer’s disease. Mice engineered to lack both alleles of the IDE gene show a 50% decrease in Aβ degradation, resulting in cerebral accumulation of Aβ. Studies of genetically inherited forms of Alzheimer’s show reduction in both IDE expression and catalytic activity among affected individuals.
