Preserved Blood RNA Purification Kit II (for use with PAXgene Blood RNA Tubes)

Norgen’s Preserved Blood RNA Purification Kit II provides a rapid method for the isolation and purification of total RNA from blood that has been preserved using PAXgene Blood RNA Tubes*. The kit purifies all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA (miRNA) and small interfering RNA (siRNA). The RNA is preferentially purified from other cellular components such as proteins, without the use of phenol or chloroform.

Purification is based on spin column chromatography using Norgen’s proprietary resin as the separation matrix. Norgen’s proprietary resin provides superior affinity to the full size range of RNA molecules, resulting in large and small RNA (miRNA) purification with better linearity and sensitivity. The purified RNA is of the highest integrity, and can be used in a number of downstream applications including real time RT-PCR, RT-PCR, Northern blotting, RNase protection and primer extension, expression profiling, miRNA cloning and amplification and Next Generation Sequencing.

PAXgene Blood RNA Tubes are a product of PreAnalytiX GmbH.  PAXgene Blood RNA Tubes are not provided.
