Norgen’s Plasma/Serum Circulating and Exosomal RNA Purification Kit (Slurry Format) provides a fast, reliable and simple procedure for isolating circulating RNA and exosomal RNA from plasma and serum samples ranging from 0.25 mL to 5 mL. This kit is able to isolate all sizes of circulating and exosmal 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.Preparation time for a single sample is less than 40 minutes. The purified plasma/serum free-circulating and exosmal 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.
