IDE Human, Active Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain (42-1019 a.a) containing a total of 984 amino acids, having a molecular mass of 114 kDa.
IDE is fused to a 6 amino acid His-tag at C-terminus and is purified by proprietary chromatographic techniques.

The IDE solution (0.5mg/ml) contains 10% Glycerol, 100mM NaCl, 0.05% Brij35 and 20mM Tris-HCl buffer (pH 7.5). 

Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.

Greater than 90.0% as determined by SDS-PAGE.

Specific activity is greater than 3,000 pmol/min/ug in which 1 unit will convert 1.0 pmole of Mca-RPPGFSAFK(Dnp)-OH to MCA-Pro-Leu-OH per minute at pH 7.5 at 25°C.

Insulin-degrading enzyme (IDE) is a crucial protease that plays a significant role in maintaining glucose homeostasis by degrading insulin and other bioactive peptides. Dysregulation of IDE has been implicated in various metabolic disorders, particularly type 2 diabetes mellitus. IDE is also associated with the clearance of amyloid-beta peptides in the brain, making it relevant to Alzheimer's disease pathology. Studying the recombinant form of IDE is fundamental to understanding its functional mechanisms and exploring potential avenues for therapeutic interventions.

The primary goal of this research is to express and purify recombinant IDE using diverse expression systems. Recombinant DNA techniques will be employed to construct expression vectors containing the IDE gene, followed by expression in bacterial, yeast, or mammalian cell-based systems. The recombinant IDE will be purified using affinity chromatography or other appropriate methods, facilitating subsequent biochemical and biophysical characterization.

The second objective is to investigate the substrate specificity and catalytic activity of the purified IDE. In vitro enzymatic assays will be conducted to analyse the ability of the recombinant IDE to degrade insulin and other potential substrates. The effects of various factors, such as pH, temperature, and potential modulators, on IDE activity will be evaluated. Additionally, the interactions between IDE and its substrates will be explored using binding assays.

The third objective is to elucidate the three-dimensional structure of the IDE recombinant using techniques like X-ray crystallography or nuclear magnetic resonance (NMR) spectroscopy. Structural insights into the active site and binding pockets of IDE will provide valuable information for understanding its substrate recognition and catalytic mechanisms. This knowledge could be instrumental in designing targeted therapeutic compounds.

By characterizing the IDE recombinant, this research aims to contribute to our understanding of its role in insulin metabolism, glucose regulation, and potential therapeutic applications. The findings from this study may have implications for the development of novel treatments for diabetes and other related disorders.
