Features and benefits
- Assure the best outcomes for delicate applications such as NGS.
- MicroRNA mapping during sequencing runs could be increased by up to ten times to cut expenses.
- Small-scale RNA concentration into 8 μL
- Perfect for concentrating RNA extracted from exosomes, plasma, serum, urine, and other body fluids, as well as any RNA samples that were first purified in large quantities.
- Effective RNA removal from enzymatic processes: in vitro transcription, DNase treatment, and labeling
- Cleanup of RNA that has been isolated using various techniques, such as phenol/chloroform extractions
- Processing in the rapid spin-column format is quick and simple.
- Appropriate for RNA of all sizes, ranging from microRNA (miRNA) to large rRNA
- No extractions of phenol or chloroform
- EXTRAClean spin column chromatography, which uses Norgen's exclusive separation matrix, is the basis for purification.
A quick way to purify, clean up, and concentrate up to 10 μg of RNA extracted using phenol/guanidine-based protocols and from a variety of upstream enzymatic reactions, including DNase treatment, labeling, and in vitro transcription, is offered by Norgen's EXTRAClean RNA Clean-Up and Concentration Micro-Elution Kit. It is possible to concentrate small amounts of RNA of all sizes, from large mRNA and ribosomal RNA to microRNA (miRNA) and small interfering RNA (siRNA), using an elution volume of at least 8 μL.
Without the use of phenol or chloroform, RNA is preferentially separated from other reaction constituents like proteins, RNases, and nucleotides. To reduce contamination traces and guarantee the best results for delicate applications like NGS, the EXTRAClean columns undergo a rigorous processing and quality control procedure.
RNase protection and primer extension, Northern blotting, end-point or quantitative reverse transcription PCR, expression array assays, and next-generation sequencing are just a few of the downstream uses for purified RNA, which has the highest integrity.

Features and benefits
- Make sure sensitive applications like NGS get the best results possible.
- MicroRNA mapping during sequencing runs can be increased up to tenfold to reduce costs.
- Exosomes from intact plasma or serum are purified and enriched for functional research.
- Variable volume of plasma or serum input.
- No carrier RNA, Proteinase K treatment, or phenol extractions are needed.
- There is no need for time-consuming filtration, ultracentrifugation, or specialized syringes.
- Neither an overnight incubation period nor precipitation reagents are needed.
- Suitable for serum or plasma from any species.
- Pure exosomes are devoid of any additional RNA-binding proteins.
- Using Norgen's exclusive resin separation matrix, EXTRAClean Mini Spin Column chromatography serves as the basis for purification.
- Small RNA sequencing is one of the many downstream uses for the purified RNA that are appropriate.
Norgen’s EXTRAClean Plasma/Serum Exosome Purification and RNA Isolation Mini Kit is an all-in-one system for exosome purification and subsequent exosomal RNA isolation from plasma/serum sample volumes ranging from 50 μL to 1 mL. The purification process uses Norgen's proprietary resin in spin column chromatography. To reduce contamination traces and guarantee the best results for delicate applications like NGS, the EXTRAClean columns undergo a rigorous processing and quality control procedure.
The kit separates extracellular vesicle RNA of all sizes, including microRNA. It has a distinct advantage over other kits on the market because it does not require any specialized equipment, extension tubes, protein precipitation reagents, phenol/chloroform, or protease treatments. The kit enables the user to elute into a variable elution volume between 50 and 100 µL.
The purified RNA has the highest integrity and is devoid of any circulating RNA bound to proteins. Numerous downstream processes, such as real-time PCR, NGS application, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays, can use the purified RNA.
