• The Acetylcholinesterase Assay Kit provides a convenient method for the detecting AChE activity and screening for inhibitors.
• The kit uses DTNB to quantify the thiolcholine produced from the hydrolysis of acetylthiolcholine by AChE.

Description

AchE Inhibitor Screening Kit (Colorimetric) provides a rapid, simple, sensitive, and reliable test suitable for high-throughput screening of AchE inhibitors.

ACETYLCHOLINESTERASE (EC 3.1.1.7, AChE), also known as RBC cholinesterase, is found primarily in the blood and neural synapses. AChE catalyzes the hydrolysis of the neurotransmitter acetylcholine into choline and acetic acid, a reaction necessary to allow a cholinergic neuron to return to its resting state after activation. Inhibition of the enzyme leads to acetylcholine accumulation, hyperstimulation of nicotinic and muscarinic receptors, and disrupted neurotransmission. AChE inhibition is an important target for the management of Alzheimer’s disease. In addition to Alzheimer’s disease, AChE inhibitors have been useful in the diagnosis or treatment of diseases such as glaucoma, myasthenia gravis, bladder distention, and more.

The Attogene Acetylcholinesterase Inhibitor Assay is based on an improved Ellman method, in which thiocholine produced by the action of acetylcholinesterase forms a yellow color with 5,5′-dithiobis(2-nitrobenzoic acid). The intensity of the product color, measured at 412nm, is proportionate to the enzyme activity in the sample.

The Acetylcholinesterase Assay Kit provides a convenient method for the detecting AChE activity and screening for inhibitors.
The kit uses DTNB to quantify the thiolcholine produced from the hydrolysis of acetylthiolcholine by AChE.

Introduction

This product is suitable for rapid extraction of RNA (include miRNA) from tissue, cells, blood, s and other clinical samples. RNA can be used directly for RT-PCR, quantitative RT-PCR, test of virus DNA and so on.

Principle

This product is based on silica column purification. Remove paraffin by Buffer DPS. Sample lysis withproteinase K digestion requires only 15 minutes. After lysis, samples are incubated at 80ºC for 15 minutes. Transfer to an adsorption column and RNA is adsorbed on the membrane, while protein is not adsorbed andis removed with filtration. After washing proteins and other impurities, RNA was finally eluted with low-saltbuffer.

Advantages

• Efficient DNA removal – one step RNA extraction can effectively remove genomic DNA
• High quality – one step RNA extraction reagent combined with silica gel column can obtain the highest concentration
• Fast – the whole extraction only takes 15-25 minutes
• Nontoxic – no toxic phenol chloroform extraction is required in the extraction

Storage and Stability

Proteinase K should be stored at 2–8°C upon arrival. DNase I should be stored at -20°C. However, short-term storage (DNase I up to 1 weeks, Proteinase K up to 8 weeks) at room temperature (15–25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15–25°C) and are stable for at least 18 months under these conditions.
