Product Info
Overview
Isolate all sizes of circulating and exosomal RNA, including microRNA
Versatile plasma and serum input volumes
Concentrate circulating and exosomal RNA into small elution volumes
Isolate inhibitor-free circulating and exosomal RNA
Bind and elute all RNA irrespective of size or GC content, without bias
Available in Spin Column or 96-well plate formats
Process 96-well plates using vacuum or centrifugation
Purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services
Compatible with Streck Cell-Free RNA BCT® Tubes
Purification is based on Norgen’s proprietary resin matrix
These kits are able to isolate all sizes of circulating and exosomal RNA, including microRNA, without the use of phenol or chloroform. The slurry format provides an advantage over other available kits in that it does not require extension tubes for the purification of free-circulating and exosomal RNA from large sample volumes. RNA can be isolated from either fresh or frozen samples using this kit. This kit is suitable for the isolation of RNA from serum or plasma prepared from blood collected only on either EDTA or citrate. Plasma samples prepared from blood collected on heparin should not be used as heparin can significantly interfere with many downstream applications including RT-PCR. The purified plasma/serum free-circulating and exosomal RNA is eluted in an elution solution that is compatible with PCR, qPCR, methylation-sensitive reverse transcription qPCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, expression array assays, and NGS.
Free-circulating plasma and serum RNA can serve as both tumor- and fetal-specific markers for cancer detection and prenatal diagnosis. As well, free-circulating RNAs have the potential to provide biomarkers for other disease states. Free-circulating RNA in plasma or serum are usually present as short fragments of less than 1000nt, and free-circulating miRNA (21nt) can also be found in plasma and serum.
