Description

The cloning kits are available with a variety of competent cells, or without competent cells, depending upon your needs and budget. This product comes in Supply Center packaging, which features an additional outer box that holds both the TOPO vector box and the competent cells box. This special packaging helps ensure that visitors to a Supply Center obtain the complete kit. Each kit uses the pCR™ 2.1-TOPO TA vector with convenient restriction sites for subcloning.
pCR™ 2.1-TOPO™ TA vector: cloning and subcloning simplicity
The pCR 2.1-TOPO TA vector is linearized with 3'-thymidine (T) overhangs for direct ligation of Taq polymerase–amplified PCR products (TA cloning) and is “activated” with covalently bound Topoisomerase I. There is no need to add ligase and cloning is complete in 5 minutes. EcoRI sites flanking the PCR product insertion site allow for easy excision of inserts or use any combination of 15 convenient restriction sites flanking your PCR insert for easy, directional subcloning.
pCR 2.1-TOPO TA clone selection and manipulation
The pCR 2.1-TOPO TA vector contains both ampicillin and kanamycin resistance markers and the LacZα gene for blue/white screening.
Simplified TOPO-based cloning
Using TOPO cloning technology, there is no need for PCR primers containing specific sequences, post-PCR procedures, vector preparation, or other time-intensive DNA manipulation steps. Just add your PCR reaction straight to the provided topoisomerase-charged vector, incubate 5 minutes, and transform E. coli competent cells.
Efficient cloning
With up to 95% of clones carrying the desired insert, you can screen less clones, saving time and money. The pCR; 2.1-TOPO TA vector used in this kit comes with 3'-T overhangs for efficient ligation of Taq polymerase–amplified PCR products, which contain 3'-A overhangs.
The standard in cloning
When it comes to cloning, TOPO™ cloning technology has been a reliable partner for thousands of scientists for over ten years. Fast, simple-to-use, and efficient, TOPO™ cloning has been applied to many different vectors for a wide array of applications.
TOPO TA Cloning Kits for Subcloning: kit options
The TOPO TA Cloning Kit for Sequencing can be purchased with a variety of competent cells that deliver different advantages depending upon your needs:

• General cloning: TOP10 cells (Cat. No. K4500-01, K4500-40)
• High-efficiency cloning: TOP10 Electrocomp™ Cells (Cat. No. K4560-01, K4560-40)
