Description

TArget Clone and TArget Clone -Plus- are high efficient TA cloning kits. TArget Clone [Code No. TAK-101] can be applied to the TA cloning of PCR products amplified using Taq DNA polymerase, Blend Taq [Code No. BTQ-101], Blend Taq -Plus- [Code No. BTQ-201] or KOD Dash [Code No. LDP-101]. Almost all PCR products having dA overhanging at the 3'end are available. TArget Clone -Plus- [Code No. TAK-201] can be applied to the TA cloning of blunt-end PCR products amplified using KOD -Plus- [Code No. KOD-201] or KOD FX [Code No. KFX-101]. TArget Clone -Plus- contains 10xA-attachment mix. This reagent is a mixture of anti-KOD DNA polymerase antibody specific to KOD 3'→5' exonuclease activity (proof-reading activity) and Taq DNA polymerase, which exhibits terminal transferase activity. The 10 x A-attachment mix allows for blunt end PCR products to acquire overhanging dA at the 3'-ends.

Application data

Example 1.TA cloning of a 500 bp-PCR product amplified with KOD- Plus- and Blend Taq.

Human b-globin gene (0.5 kb) was amplified using KOD -Plus- [Code No. KOD-201] or Blend Taq [BTQ-101]. Then, the unpurified PCR products were cloned into the pTA2 vectors using TArget Clone or TArget Clone -Plus- according to each instruction manual. Subsequently, DH5a competent cells were transformed using the ligation products and cultured on the LB/Amp/X-gal plate overnight at 37ºC. As shown Fig. 1, PCR products from Blend Taq were successfully cloned into the pTA2 Vector using both kits. And, PCR products from KOD -Plus- was cloned efficiently into pTA2 Vector using TArget Clone -Plus-.
