Features
- No liquid nitrogen required for homogenization - Liquid nitrogen is not required for homogenization of samples, making RNA purification rapid and convenient.
- Isolate RNA from a wide range of samples - Total RNA can be isolated from a wide range of plant and filamentous fungi samples.
- Isolate a diversity of RNA species - All sizes of RNA are isolated from large mRNA down to microRNA, without the use of phenol or chloroform.
- Isolate total RNA, including viral RNA - RNA samples can be used for the detection of viral pathogens, as viral RNA is isolated with the total RNA.
- High yield of RNA - High yields of purified RNA can be isolated with this kit.
- No phenol:chloroform extractions - Total RNA is isolated without the use of harmful chemicals such as phenol or chloroform. RNA is of the highest quality and can be used in a number of downstream applications.
Norgen's Plant/Fungi Total RNA Purification Kit provides a rapid method for the isolation and purification of total RNA, including viral RNA, from a wide range of plant and filamentous fungal species. Total RNA can be purified from fresh or frozen plant tissues, plant cells or filamentous fungi samples using this kit. All sizes of RNA are purified, from large mRNA and ribosomal RNA down to microRNA (miRNA) and small interfering RNA (siRNA). The procedure is rapid and convenient, as it does not rely on the use of liquid nitrogen in order to homogenize the samples. Purification is based on spin column chromatography using Norgens proprietary resin as the separation matrix. The RNA is preferentially purified from other cellular components, such as proteins, without the use of phenol or chloroform. The purified RNA is of the highest integrity, and can be used in a number of downstream applications including real time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.
Purification is based on spin column chromatography using Norgens proprietary resin as the
separation matrix. The RNA is preferentially purified from other cellular components such as
proteins without the use of phenol or chloroform. The process involves first macerating the cells
or tissue in a mortar with the provided Lysis Solution (please see the flow chart on page 4). The
Lysis Solution contains detergents, as well as large amounts of a chaotropic denaturant that will
rapidly inactivate RNases and proteases that are present. Alternatively, liquid nitrogen can be
used to homogenize the sample. The lysate is then spun in a microcentrifuge in order to pellet
and remove any debris. Ethanol is then added to the clarified lysate, and the solution is loaded
onto a spin-column. Norgens resin binds nucleic acids in a manner that depends on ionic
concentrations, thus only the RNA will bind to the column while most of the DNA and proteins are
removed in the flowthrough. The bound RNA is then washed with the provided Wash Solution in
order to remove any remaining impurities, and the purified total RNA is eluted with the Elution
Buffer. The purified RNA is of the highest integrity, and can be used in a number of downstream
applications.

Isolate RNA from a Wide Range of Plants
RNA was isolated from 50 mg samples of tobacco leaves (Lanes 1 and 2), tomato leaves (Lanes 3 and 4), peach leaves (Lanes 5 and 6) and grape leaves (Lanes 7 and 8) using Norgens Plant/Fungi Total RNA Purification Kit, and 5 uL aliquots were run on a 1X MOPS 1 % formaldehyde-agarose gel. Total RNA was isolated in all cases, including all small microRNA species Lane M is Norgens 1 kb RNA Ladder.Detection of Plum Pox Virus in Peach Leaves
Total RNA was isolated from two 50 mg samples of peach leaves using Norgens Plant/Fungi Total RNA Purification Kit, and 3 m L of the RNA was used in an RT-PCR reaction for the detection of plum pox virus. Plum pox virus was detected from both samples, indicating that the RNA is of a high quality and that the kit is highly sensitive for total RNA isolation.- Quantitative, real-time RT-PCR
