EXTRAClean Urine Exosome Purification and RNA Isolation Kits
Product Info
Document
Product Info
Overview
Ensure optimal results for sensitive applications like NGS
Up to a tenfold increase in microRNA mapping during sequencing runs to reduce costs
Purification and enrichment of intact urinary exosomes for functional studies.
Bind and elute all RNA irrespective of size or GC content, without bias.
Isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias.
No phenol extractions, Proteinase K treatment, nor carrier RNA required.
No time-consuming ultracentrifugation, filtration nor special syringes are required.
No precipitation reagents nor overnight incubation required.
Compatible with urine from any species.
Pure exosomes are purified and are free-from any other RNA-binding proteins.
Purification is based on EXTRAClean spin column chromatography that uses Norgen’s proprietary resin separation matrix.
Norgen’s EXTRAClean Urine Exosome Purification and RNA Isolation Mini Kit constitutes an all-in-one system for the purification of exosomes and the subsequent isolation of RNA from different urine sample volumes ranging from 250 μL to 1 mL. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. The EXTRAClean columns undergo stringent processing and rigorous quality control measures to minimize contamination traces, ensuring optimal results for sensitive applications such as NGS. The kit is designed to isolate all sizes of RNA, including microRNA. The kit provides a clear advantage over other available kits in that it does not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the kit allows the user to elute into a flexible elution volume ranging from 50 μL to 100 μL. The purified RNA is free from any protein-bound circulating RNA and of the highest integrity. The purified RNA can be used in a number of downstream applications including real time PCR, reverse transcription PCR, NGS application, Northern blotting, RNase protection and primer extension, and expression array assays.
All sizes, including miRNA and small RNA (< 200 nt)
Elution Volume
50-100 μL
