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.
Detail
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.
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.

Introduction
Hipure Microbial RNA kit is suitable for extracting high-purity total RNA from bacterial/yeast culture medium. This kit combines high-efficiency Magzol Reagent (one-step extraction reagent) and silicagel column purification technology to complete the extraction of high-purity total RNA in only 40 minutes. The obtained RNA can be directly used in RT-PCR, Northern blot, poly-A + purification, nucleic acid protection and in vitro translation.

Principle
Hipure silica gel column is based on glass fiber filter membrane with high binding force. Under the condition of high concentration of ionizing agent (such as guanidine hydrochloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bond and electrostatic, while protein and other impurities are not adsorbed and removed. The filter membrane adsorbed with nucleic acid is washed to remove the residual protein and salt. Finally, the nucleic acid adsorbed on the filter membrane can be washed out with low salt buffer (such as buffer TE) or water. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.
Advantages
Fast – several samples can be extracted in 30 minutes
High purity – the purified RNA can be directly used in various downstream applications
High recovery – RNA can be recovered at the level of PG
Good repeatability – silica gel column purification technology can obtain ideal results every time
Broad spectrum – it can deal with various bacteria, including Gram-positive bacteria that are difficult to be lysed
Sufficient components – the kit contains carried wall breaking enzymes and glass beads

Storage and Stability
Buffer PHC 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, Buffer PHC up to 12 weeks) at room temperature(15–25°C) does not affect their performance. The remaining kit components can be stored at roomtemperature (15–25°C) and are stable for at least 18 months under these conditions.

Isolate high quality DNA from a broad variety of phage strains
High yields of total DNA
Fast and easy processing using a rapid spin-column format
No phenol or chloroform extractions or cesium chloride banding required
High yields of DNA recovered3-15 µg DNA from 106-1010 pfu/ mL of enriched phages
This kit provides a rapid spin column method for the purification of total DNA from a broad spectrum of bacteriophages propagated in bacteria grown in liquid cultures. The DNA is isolated without the use of phenol, chloroform or cesium chloride banding procedures. The spin-column based procedure is rapid and can be completed in less than 45 minutes. The kit is highly efficient for processing small volumes of phage supernatant (500 µL – 1 mL) and with the optional DNase and Proteinase K treatments phage DNA yields are maximized while host DNA contamination is minimized. Purified total phage DNA is of the highest integrity, and can be used in a number of downstream applications including PCR, qPCR, Restriction Fragment Length Polymorphism (RFLP), sequencing, cloning, Southern Blot and more.

Storage Conditions and Product Stability All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 1 year after the date of shipment.
Follicle-Stimulating Hormone (FSH) allows for progression of ovarian folliculogenesis, and enables Sertoli cell proliferation in the testis. Anti-FSH reacts with FSH-producing cells, therefore FSH staining is useful for classifying pituitary cancers and understanding pituitary disease.
