- Isolate true total RNA including siRNA and microRNA
- No phenol extractions
- Purify high-quality RNA in 30 minutes
- Purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen's NGS services
- Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
Norgen’s Preserved Blood RNA Purification Kit I provides a rapid method for the isolation and purification of total RNA from blood that has been preserved using Tempus™ 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.

FAQs
Spin Column
- Incomplete lysis of blood.
Ensure that the appropriate amount of Lysis Solution was used.
- An alternative elution solution was used.
It is recommended that the Elution Solution supplied with this kit be used for maximum RNA recovery.
- Ethanol was not added to the lysate.
Ensure that the appropriate amount of ethanol is added to the lysate before binding to the column.
- Ethanol was not added to the Wash Solution.
Ensure that 50 mL of 95% ethanol is added to the supplied Wash Solution prior to use.
- Insufficient centrifugation time and speed when pelleting the stabilized blood RNA before column purification.
Centrifuge the samples for at least 30 minutes or longer at 4,000 x g or higher. The RNA pellet was lost during decanting Pour off the supernatant slowly and carefully.
- Insufficient solubilization of blood.
Ensure that the appropriate amount of Lysis Buffer was used.
- Centrifuge temperature is too low.
Ensure that the centrifuge remains at room temperature throughout the procedure. Temperatures below 15°C may cause precipitates to form that can cause the columns to clog.
- RNase contamination.
RNases may be introduced during the use of the kit. Ensure proper procedures are followed when working with RNA. Please refer to “Working with RNA” at the beginning of the protocol's user guide.
- Procedure not performed quickly enough.
In order to maintain the integrity of the RNA, it is important that the procedure be performed quickly.
- Improper storage of the purified RNA.
For short term storage RNA samples may be stored at -20°C for a few days. It is recommended that samples be stored at -70°C for longer term storage.
- RNA was not washed 3 times with the provided Wash Solution A.
Traces of salt from the binding step may remain in the sample if the well is not washed 3 times with Wash Solution A. Salt may interfere with downstream applications, and thus must be washed from the well.
- Ethanol carryover.
Ensure that the dry spin under Column Wash in the centrifugation protocol or the extended vacuum in the vacuum protocol is performed in order to remove traces of ethanol prior to elution. Ethanol is known to interfere with many downstream applications.
