Plasma/Serum Circulating and Exosomal RNA Purification Maxi Kit (Slurry Format)
Norgen’s Plasma/Serum Circulating and Exosomal RNA Purification Maxi Kit (Slurry Format) provides a fast, reliable and simple procedure for isolating circulating RNA and exosomal RNA from various amounts of plasma/serum ranging from 2 mL to 5 mL. Free-circulating RNA and exosomal RNA in plasma and serum has the potential to provide biomarkers for certain cancers and disease states, and includes tumor-specific extracellular RNA in the blood. Norgen’s Plasma/Serum Circulating and Exosomal RNA Purification Maxi Kit (Slurry Format) provides an efficient method for the purification of all sizes of these fragmented free-circulating RNAs and exosomal RNAs from human plasma or serum.
Exosomes are 40 - 100 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. The exosomes contain cell-specific proteins, lipids and RNAs, which are transported to other cells, where they can alter function and/or physiology. 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. Recent work has demonstrated the presence of distinct subsets of microRNAs within exosomes which depend upon the tumour cell type from which they are secreted. 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.

Storage Conditions and Product Stability
All buffers should be kept tightly sealed and stored at room temperature (15-25oC) for up to 1 year without showing any reduction in performance. It is recommended to warm PS Solution A, PS Solution B and PS Solution C for 20 minutes at 60oC if any salt precipitation is observed.
