Propargyl-PEG13-acid consists of an alkyne group and a carboxylic acid. The carboxylic acid reacts with amine groups to form amide bonds in the presence of EDC or HATU as an activator. The alkyne group is commonly used in copper catalyzed azide-alkyne Click Chemistry reactions. The hydrophilic PEG units enhance the solubility of the molecule in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Introduction

HiPure PCR Pure Mini Kit uses proprietary chemistry and HiPure technology to recover DNA Fragments between 70bp-30kbp with yields exceeding 85%. DNA is suitable for ligations, PCR, sequencing, restriction digestion, or various labeling reactions. In addition, this kit can be also used to recover DNA directly from enzymatic reactions such as PCR and enzyme digestion reactions.

Compared with the gel purification kit, this product uses guanidine hydrochloride mediated adsorption, which have better A260/A230 ratio.

Principle

The HiPure system uses a simple bind-wash-elute procedure. Gel slices are dissolved in a buffer containing a pH indicator, allowing easy determination of the optimal pH for DNA binding, and the mixture is applied to the column. Nucleic acids adsorb to the silica-gel membrane in the high-salt conditions provided by the buffer. Impurities are washed away and pure DNA is eluted with a small volume of low-salt buffer provided or water, ready to use in subsequent applications.

Advantages

• High recovery efficiency – ≥85% DNA recovery
• Fast – isolation can be completed in 10 minutes by column gel method
