Main Functions
Extract pathogen DNA/RNA from whole blood, body fluid, serum, plasma, sputum, immersion solution, tissue homogenate supernatant, etc.
This product is based on silica gel purification. The sample is lysed and digested with lysate and protease, DNA/RNA is released into the lysate. Transfer to an adsorption plate and filter column. DNA/RNA is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, DNA / RNA is finally eluted with low-salt buffer (10 MmTris, pH 8.0).
Advantages
Fast – column purification, several samples can be finished in 30 mins
High quality – high purity total RNA/DNA can be directly used in various sensitive downstream applications
Safe – no phenol chloroform extraction required
Sensitive – DNA/RNA can be recovered at the level of PG

Storage and Stability
Proteinase K and DNase I (Powder) should be stored at 2–8°C upon arrival. However, short-term storage (DNase I up to 1 week, Proteinase K up to 8 weeks) at room temperature (15–25°C) does not affecttheir performance. The remaining kit components can be stored at room temperature (15–25°C) and are stable for 18 months under these conditions.
These kits provide 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. These kits can purify RNA from fresh or frozen serum or plasma samples prepared from blood collected 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 such as RT-PCR. The purified plasma/serum RNA 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. The EXTRAClean columns undergo stringent processing and rigorous quality control measures to minimize contamination traces, ensuring optimal results for sensitive applications such as NGS.
Background
Cell-free circulating RNA, including exosomal RNA in plasma or serum, has the potential to provide biomarkers for certain cancers and disease states, and includes tumor-specific extracellular RNA in the blood. 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.
EXTRAClean Plasma/Serum RNA Purification Mini Kit
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. The purified plasma/serum RNA is eluted in a flexible final volume of 10 μL to 25 μL.
EXTRAClean Plasma/Serum RNA Purification Midi Kit
This utilizes a two-column method, and can purify RNA from fresh or frozen serum or plasma samples prepared from blood collected on either EDTA or Citrate, from volumes ranging from 250 μL to 1.5 mL. The first column will handle the large volume input of bodily fluids that is followed by a concentration on a mini column for a final elution of 50 μL to 100 μL.
EXTRAClean Plasma/Serum RNA Purification Maxi Kit
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 2 mL to 5 mL. The first column will handle the large volume input of bodily fluids that is followed by a concentration on a mini column for a final elution of 50 μL to 100 μL.
