These kits provide a fast, reliable and convenient method to sequentially isolate and concentrate exosomal RNA as well as Free-Circulating RNA from different urine sample volumes. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. These kits are designed to isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias. These kits provide a clear advantage over other available kits since they do not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the kits allow the user to elute into a flexible elution volume ranging from 50 µL to 100 µL. The RNA isolated from the purified exosomes is free from any protein-bound circulating RNA and is of the highest integrity. Moreover, the free-circulating, protein-bound, RNA is free from any exosomal RNA. The purified RNA 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.

Storage Conditions and Product Stability
All buffers should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipping. It is recommended to warm Lysis Buffer A for 20 minutes at 60°C if any salt precipitation is observed.
Important Note
Urine samples stored at -70°C, -20°C or at 4°C will develop some precipitation due to the aggregation of some of the highly abundant proteins in urine. Eliminating these precipitates using centrifugation or filtration may cause the loss of exosomes. Furthermore, these precipitates may affect the quality of the purified nucleic acid. We recommend the use of Norgen’s Urine Preservative when collecting urine samples, which is designed for the preservation of nucleic acids and proteins in fresh urine samples at ambient temperatures. The components of the Urine Preservative allow samples to be stored for over 2 years at room temperature with no detected degradation of urine DNA, RNA or proteins. Norgen’s Urine Preservative is available as a liquid format in Norgen’s Urine Preservative Single Dose Ampules, as well as in a dried format in Norgen’s Urine Collection and Preservation Tubes.

The NGS DNA Fragmentation & Library Prep Kit (ion torrent platform) was developed for construction of high quality libraries for next generation sequencing for ion torrent platform. The kit uses intact genomic DNA (both EDTA-free DNA and DNA in TE buffer are compatible) as input DNA without an additional DNA fragmentation step. Our NGS kit has a fast and simple workflow with only three step. In addition, all steps can be performed in one tube. The DNA libraries can be generated within one hour with less than 10 minutes of hands-on time. Library multiplexing up to 12 samples is possible.
NGS DNA Fragmentation & Library Prep Kit Workflow
The incorporation of DNA fragmentation in the kit makes it possible to directly use intact genomic DNA as input DNA without the need of mechanical DNA shearing or enzymatic DNA fragmentation. The protocol is optimized to generate libraries from 200 bp to 500 bp in size. The library size is inversely correlated with the incubation time of step 1 at 20°C.
Kit features:
Library conversion efficiency for NGS DNA Fragmentation & Library Prep Kit (Ion Torrent Platform). 100 ng, 300 ng and 500 ng of DNA were used as input.
NGS DNA Fragmentation & Library Prep Kit (Ion Torrent Platform): Library size distribution with different incubation time.
