Plasma/Serum RNA Purification Mini Kit
This kit provides a fast, reliable and convenient method to purify and concentrate high quality, high purity and inhibitor-free cell-free circulating and exosomal RNA using a convenient spin column method. This kit can purify RNA from fresh or frozen serum or plasma samples prepared from blood collected on either EDTA or Citrate, from volumes ranging from 50 µL to 200 µL. Plasma samples prepared from blood collected on heparin should not be used, as heparin can significantly interfere with many downstream applications such as RT-PCR.
The purified plasma/serum RNA is eluted in a flexible final volume of 10 µL to 25 µL and is fully compatible with all downstream applications including PCR, qPCR, methylation-sensitive reverse transcription qPCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, expression array assays, and NGS.
Plasma/Serum cell-free circulating RNA or exosomal RNA has the potential to provide biomarkers for certain cancers and disease states. Exosomes are 40 - 150 nm membrane vesicles, which are secreted by most cell types. Exosomes can be found in saliva, blood, urine, amniotic fluid and malignant ascitic fluids, among other biological fluids. Evidence has been accumulating recently that these vesicles act as cellular messengers, conveying information to distant cells and tissues within the body. These exosomes may play a functional role in mediating adaptive immune responses to infectious agents and tumours, tissue repair, neural communication and transfer of pathogenic proteins. For this reason exosomal RNAs may serve as biomarkers for various diseases including cancer. As the RNA molecules encapsulated within exosomes are protected from degradation by RNAses they can be efficiently recovered from biological fluids, such as plasma or serum.
