Description

The ExcelTaq™ Hot Start II DNA Polymerase is a mixture of an aptamer-based inhibitor and a recombinant thermo-stable Taq DNA polymerase designed for preventing or minimizing non-specific DNA amplification in PCR reaction. The inactivation of polymerase is achieved by a reversible binding of the aptamer to the polymerase at temperatures below 45°C. The aptamer inhibitor releases polymerase during normal PCR cycling. The aptamer-based inhibition omits the time-consuming initial activation step required by chemically modified or antibody-based hot start polymerases.

The high specificity and sensitivity of ExcelTaq™ Hot Start II DNA Polymerase allows sensitive detection from limited amount of DNA templates, such as 1 pg of cDNA or 1 fg of plasmid DNA. With a high DNA synthesis rate and high thermo-stability, the ExcelTaq™ Hot Start II DNA Polymerase allows reactions to be set up at room temperature and is suitable for common and specialized PCR applications

Features

• Aptamer-based hot start PCR
• Reversible enzyme inactivation
• Omits extra enzyme activation step

Applications 

• High specificity PCR
• Generation of PCR products for TA cloning
• Routine PCR, multiplex PCR, colony PCR, and RT-PCR

Storage

-20°C for 24 months

Introduction

HiPure Gel Pure DNA Kit uses proprietary chemistry and HiPure technology to recover DNA fragments between 80bp-15kbp with yields exceeding 80%. 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.

Note: This kit can only recover 200mg of gel at most. If it is larger than 200mg, the column may be blocked. This column can only recover 5μg of DNA at most.

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 – up to 80% DNA recovery
• Low elution volume – elution volume can be as low as 10μl
• General – recover DNA fromgel or enzyme-driven reaction solutions such as PCR
• Fast – isolation can be completed in 10-15 minutes by column gel method
