T&A™ Cloning Vector, 20 preps, Cat.No.: YBB-TA-FYC002-20P-Vector, Size: 20 preps, Store at -20°C, 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.
