• 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.

Description

Attogene’s Microcystin Test Kit (Rapid – Recreational Water) can be used to detect microcystins in liquid samples; highly sensitive, rapid, robust screening kit for algae toxins microcystins and nodularins.

The most frequently reported cyanobacterial toxins are the hepatotoxic microcystins (MCs). MCs are peptides with a molecular weight ranging from 900 to 1,100 Da. They consist of seven amino acids of which the two terminal amino acids of the linear peptide are condensed to form a cyclic compound.

A tiered notification system which takes different actions based on different numeric thresholds for microcytin-LR concentrations in recreational waters has been developed. This is guidance that allows states to take various actions—such as posting information about harmful algal blooms (HABs), issuing a recreational public health advisory, or temporarily closing recreational waters through a no contact advisory—depending on the severity of the bloom event.

Microcystin-LR

Informational sign postings about HABs at recreational waters: < 6 μg/L
Recreational public health advisory: 6 μg/L
Elevated recreational public health advisory (e.g. no contact): 20 μg/L

Introduction

MagPure Circulating DNA Mini Kit is designed for purification of high quality circulating DNA (cfDNA) fromcell-free body fluids (such as plasma, serum). The purified DNA is suitable for direct use in downstream applications such as PCR, real-time PCR, biochip analysis and NGS.

Principle

This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and protease. DNA is released into the lysate. After adding magnetic particles and binding solution, DNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol to remove salts, and finally DNA was eluted by elution buffer.

Advantages

• Economy – less than 50% of the price of Qiagen and other imported products
• Automatic – without labour

Storage and Stability

Proteinase K, Carrier RNA and MagPure Particles G should be stored at 2–8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15–25°C) does not affect their performance. Theremaining kit components can be stored dry at room temperature (15–25°C) and are stable for at least18 months under these conditions.The entire kit can be stored at 2–8°C, but in this case buffers should beredissolved before use. Make sure that all buffers are at room temperature when used.
