endo-BCN-PEG6-t-butyl ester is a click chemistry linker. The hydrophilic PEG spacer increases solubility in aqueous media. The BCN group can react with azide-tagged molecules. The protected carboxyl group (COOH) prevents self coupling or polymerization under standard acid/amine or acid/hydroxyl coupling conditions. It can be converted to free acid under acidc condition. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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 Midi Kit enables efficient purification of these circulating nucleic acids from human plasma, serum, or urine. The extracted products can be used for clinical in vitro detection.

Principle

This product is based on silica Column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption 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.

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 thelevel of PG by silica gel column purification

Storage and Stability

Proteinase K, 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 remaining kit 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 should be redissolved before use. Make sure that all buffers are at room temperature when used.
