Alkyne-PEG2-iodide is a crosslinker containing a propargyl group and an iodine group. The propargyl group can form triazole linkage with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry reactions. Iodine (I) is a very good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research use only.

Introduction
Hipure Stool RNA Kit is specially designed for stool RNA extraction. This kit is suitable for extracting high-purity microbial or host cell RNA from ≤0.1g stool samples. The kit adopts silica gel column purification technology and original solution system, which can effectively remove humic acid and other inhibitory factors in stool samples. The purified RNA can be directly used in RT-PCR, Northern hybridization and other experiments.

Principle
The HiPure silica gel column uses a high binding ability glass fiber filter membrane as the substrate. Under the condition of high concentration of ionizing agent (such as Guanidinium chloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bonding and electrostatic and other physical factors, while protein or other impurities are not adsorbed and removed. The filter membrane that has adsorbed nucleic acids is washed to remove proteins and salts. Finally, low salt buffer solution (such as Buffer TE) or water can be used to wash out the nucleic acids adsorbed on the filter membrane. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.
The stool samples are homogenized in the lysis solution, further lysed in a high-temperature water bath, and RNA is released into the lysis solution. Chloroform extraction removes genomic DNA and impurities, transfer the supernatant to an alcohol free binding solution, purify RNA through a column, and finally elute RNA with RNase Free Water. The purified RNA can be directly used for experiments such as PCR, Southern hybridization, and enzyme digestion.
Advantages
High purity – unique adsorbent for more efficient removal of inhibitors
High concentration – maximum extraction of total RNA from stool samples
Sensitive – RNA can be purified at the level of PG
