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
