Description

Molecular cloning assisted by vectors is the most popular and common method to obtain genes of interest. Yeastern Biotech’s T&A™ Cloning Kit offers a quick, reliable and efficient method for cloning a variety of DNA sequences.

The T&A™ Cloning Kit contains the T&A™ Cloning Vector and all the reagents needed for ligation. It is a convenient pack for cloning PCR product generated using thermostable DNA polymerases, such as YEAtaq DNA polymerase, which add a single terminal 3′-dA nucleotide overhang. After ligation, the mixture can be used directly for transformation into competent cells (ECOS™) or be purified first to achieve higher transformation efficiency.

Features

• Fast ligation, completed in only 5 minutes
• More accurate results
• Accept a wide range of inserts with different sizes
• Two types of ligation buffers provided for your convenience
• Allow blue/white screening
• Contain ampicillin marker for antibiotic selection
• Include M13 primer sites for convenient sequencing

Applications

• Cloning of terminal 3’-dA nucleotides overhang PCR products up to 5 kb
