DBCO-PEG23-amine is a PEG linker which contains DBCO and amine moieties. The DBCO group is commonly used in copper-free Click Chemistry reactions. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The hydrophilic PEG spacer increases the water solubility of the compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Norgen’s EXTRAClean Urine Cell-Free Circulating RNA Purification Kits provide a fast, reliable, reproducible, and simple procedure for isolating circulating RNA and exosomal RNA from various urine inputs ranging from 250 μL and up to 30 mL. The purified RNA is of the highest integrity, and can be used in a number of downstream applications including real-time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extensions, and expression array assays.
EXTRAClean Cell-Free Circulating RNA Purification Mini Kit:
For sample volumes ranging from 250 μL to 2 mL
EXTRAClean Cell-Free Circulating RNA Purification Midi Kit:
For sample volumes ranging from 2mL to 10mL. The first column will handle the large volume input of urine that is followed by a concentration on a mini column for a final elution of 50 μL to 100 μL
EXTRAClean Cell-Free Circulating RNA Purification Maxi Kit:
For sample volumes ranging from 10 mL to 30 mL. The first column will handle the large volume input of urine that is followed by a concentration on a mini column for a final elution of 50 μL to 100 μL.

The kit includes HS Dye, HS Dilution Buffer, and two DNA Standards. The assay is accurate for DNA concentrations from 10 pg/µL to 100 ng/µL, and is highly selective for double-stranded DNA over RNA.
Features
DNA selectivity and sensitivity of the HS kit. A series of input DNA (20, 40, 60, 80, 100, and 120 ng) was used with or without the contamination of RNA.
Comparison of dsDNA HS kits. The performance of the BioDynami dsDNA HS kit is nearly identical to that of Thermo Fisher’s Qubit dsDNA HS kit.

Introduction
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).

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).

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.
