Product description

TOPcloner™ XL TA Kit is suitable for cloning Taq polymerase-amplified long (3-10 kb) PCR products (with A-tail overhangs) at room temperature in 5 min. The vector provided in this Kit contains topoisomerase covalently coupled to its ends, which allows efficient ligation of DNA fragments with A-tail overhangs to the vector without using a regular ligase. This kit provides special gel purification reagents that ensures efficient cloning of long, full-length PCR products.



- Highly efficient long PCR product (3-10 kb) cloning

- Short reaction time (5 min)

- Direct use of PCR products



- Fast and efficient cloning of long, full-length (3-10 kb) A-tailed PCR products.

Figure 1. A schematic map of pTOP TA V2 (3807 bp). 

A molecule of topoisomerase (TOPO) is covalently coupled to each of the two 3 one-nt protruding ends (nt positions 294 and 295) of pTOP TA V2 (Cat.# EZ001 and EZ011). Therefore, pTOP TA V2 is ready to form a covalent bond when mixed with PCR products with one-nt 3 A overhang. The addition of one A to the duplex DNA ends is intrinsic to Taq DNA polymerase.

Large (10 kb) size of PCR product was cloned using TOPcloner™ XL TA Kit.
