RNApure High-purity Total RNA Rapid Extraction Kit
Catalog Number：
The RNApure procedure represents a well-established technology for RNA purification. This technology combines the selective binding properties of a silica membrane with the speed of microspin technology. A specialized high-salt buffer system allows up to 100 μg of RNA longer than 200 bases to bind to the RNApure silica membrane.
Biological samples are first lysed and homogenized in the presence of a highly denaturing guanidine-thiocyanate–containing buffer, which immediately inactivates RNases to ensure intact RNA. Ethanol is added to provide appropriate binding conditions, and the sample is then applied to an RNApure Mini spin-column, where the total RNA binds to the membrane and contaminants are efficiently washed away. High-quality RNA is then eluted in 30–100 μl water.
