Butyrylcholinesterase (BCHE) is a major acetylcholine hydrolyzing enzyme in the circulation. Although it is present in significant amounts in human plasma, no endogenous physiological substrate has been described for this enzyme. It can degrade a large number of ester-containing compounds besides acylcholines, including neurotoxic organophosphate esters. Thus, it plays significant pharmacological and toxicological roles. It is thought to be involved in the pathological progression of Alzheimer's disease (AD) by depleting acetylcholine. In contrast to ACHE, it attenuates amyloid fibril formation in vitro. BCHE inhibitors have been used to delay symptoms of AD patients by virtue of their ability to enhance ACH availability. Its involvement in the cholinergic anti- inflammatory pathway connects BCHE and ACHE as possible markers of low-grade systemic inflammation observed in Type-2 diabetes, obesity, hypertension, coronary heart disease, and AD. BCHE can exist as monomers, dimers, or tetramers.

Applications:
Suitable for use in ELISA, Western Blot and SDS-PAGE.
Other applications not tested.

Recommended Dilution:
Optimal dilutions to be determined by the researcher.

Storage and Stability:
Lyophilized and reconstituted products are stable for 6 months after receipt at -70°C. Reconstitute with sterile 20mM Tris, 150mM sodium chloride, pH 8.0. Aliquot to avoid repeated freezing and thawing. Store at -70°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer

Note:
Thermal stability is described by the loss rate of the target protein. The loss rate was determined by accelerated thermal degradation by incubating the protein at 37°C for 48h, with no obvious degradation or precipitation observed. Protein loss is <5% within the expiration date under appropriate storage conditions.
