Mal-amido-PEG5-alkyne is a PEG linker containing a maleimide group and an alkyne. The hydrophilic PEG spacer increases solubility in aqueous media. The alkyne group can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

The kit offers the unique feature to isolate total RNA including small RNA and DNA from serum and plasma without the need to resort to the cumbersome phenol/chloroform extraction or a time consuming proteinase digest. RNA purified using the kit is ready for applications such as RT-PCR, Northern blotting, poly A+ RNA (mRNA) purification, nuclease protection, and in vitro translation.

Principle
This product is based on the purification method of high binding magnetic particles. The sample material is denatured in Lysis Buffer. The protein is then precipitated by Protein Precipitation Solution and pelleted by centrifugation. After adding magnetic particles and binding solution, RNA 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 RNA was eluted by Elution Buffer.
Advantages
Safe – no phenol chloroform extraction and no use of Trizol reagent
Fast – several samples can be extracted in 60 minutes by column method

Storage and Stability
MagPure Particle N should be stored at 2–8°C upon arrival. However, short-term storage (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.

Bacillus cereus is a rod-shaped, gram-positive bacterium. Some strains of B. cereus cause foodpoisoning and other diseases such as keratitis. B. cereus grows at a wide range of temperature, from 4°C to 37°C. In fact, many foodborne illnesses caused by B. cereus are a consequence of improperly cooked or improperly stored food, including dairy products and meats. The majority of food poisoning by B. cereus could be divided into two types of symptoms – the emetic type and the diarrheal type, both of which are caused by the enterotoxin produced by the bacteria.

Storage Conditions and Product Stability All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
