DBCO-TFP ester is an amine-reactive, labeling reagent used to modify proteins, antibodies, and other amine-containing biopolymers. The highly reactive DBCO group can be used in copper-free click reactions. The TFP ester can react with primary amine groups and is also less susceptible to undergo hydrolysis compared to NHS ester. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

No precipitation reagents, nor overnight incubation required
Compatible with plasma/serum from most species
Pure exosomes are purified and are free from any other RNA-binding proteins
Purification is based on spin column chromatography that uses Norgen’s proprietary resin
The purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services
Norgen’s Plasma/Serum Exosome and RNA Isolation Kits constitute all-in-one systems for the purification of exosomes and the sequential isolation of exosomal RNA from different plasma/serum sample volumes. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. These kits are designed to isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias. These kits provide a clear advantage over other available kits in that they do not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. The RNA isolated from the purified exosomes is free from any protein-bound circulating RNA and is of the highest integrity. The purified RNA can be used in a number of downstream applications including real time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.

Average Yields*
Variable depending on specimen
*Please check page 4 of the product insert for the average yields and the common RNA quantification methods.
Storage Conditions and Product Stability All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment. It is recommended to warm Lysis Buffer A for 20 minutes at 60°C if any salt precipitation is observed.
Important Note This kit is suitable for the purification of exosomes from fresh or frozen serum or plasma 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.
Free-circulating nucleic acids, such as tumor-specific extracellular DNA fragments and mRNAs in the blood or fetal nucleic acids in maternal blood, are present in serum or plasma usually as short fragments, <1000bp (DNA). HiPure Circulating DNA Mini Kit enables efficient purification of these circulating nucleic acids from human plasma, serum, or urine. Samples can be fresh or frozen (provided that they have not been frozen and thawed more than once).

Principle
This product is based on silica gel purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption plate and filter column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, nucleic acid was finally eluted with low-salt buffer (10 Mm Tris,pH 8.0).
Advantages
High yield – most optimal process, free DNA (>50bp) can be obtained to the maximum extent
High concentration – low elution volume, ensuring high nucleic acid concentration
High purity – low alcohol binding method, completely removing inhibitor and protein pollution
High recovery – DNA can be recovered at the level of PG by silica gel column purification

Storage and Stability
Proteinase K and carrier RNA should be stored at 2–8°C upon arrival. However, short-term storage(up to 12 weeks) at room temperature (15–25°C) does not affect their performance. The remainingkit components can be stored dry at room temperature (15–25°C) and are stable for at least 18 months under these conditions.The entire kit can be stored at 2–8°C, but in this case buffers shouldbe redissolved before use. Make sure that all buffers are at room temperature when used.
