R6626 MagPure Stool RNA Kit

Introduction

This product is specially designed for stool RNA extraction. The kit is suitable for extracting high-purity microbial or host cell RNA from ≤ 0.15g stool samples. The purified RNA can be directly used in RT-PCR and Northern hybridization.

Details

Principle

The Kit combines the speed and efficiency of silica-based technology with the convenient handling of magnetic particles for purification of total RNA. Samples are lysed and RNA is purified from lysates in one step through its binding to the silica surface of the particles in the presence of a chaotropic salt. The particles are separated from the lysates using a magnet and DNA is removed by treatment with RNase-free DNase. The magnetic particles are efficiently washed, and RNA is eluted in RNase-free water.

Storage and Stability

MagPure RNA Particles 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, MagPure RNA Particles 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.

Tetra(3-methoxy-N-(PEG5-prop-2-ynyl)propanamide) Methane

Tetra(3-methoxy-N-(PEG5-prop-2-ynyl)propanamide) Methane is a branched crosslinker with four terminal propargyl groups. The propargyl groups can react with azide compounds or biomolecules via copper catalyzed Click Chemistry to form a stable triazole linkage.
