TOPO® TA Cloning® kits for sequencing provide a highly efficient, 5-minute cloning reaction for the direct insertion of Taq polymerase-amplified PCR products into a plasmid vector for sequencing. Each kit uses the pCR™4-TOPO® TA vector with specially designed sequencing primer sites that return more insert sequence and less vector sequence from each reaction, and are available with a variety of competent cells, or no competent cells, depending on your needs and budget. These kits include the tools necessary to clone and select recombinant vectors containing your PCR fragment of choice.• Get more sequence—allows for more insert sequence and less vector sequence when using standard sequencing primers• Fast and easy—go from PCR to clones in just 3 steps, including a 5-minute cloning reaction• Efficient—obtain up to 95% clones with correct insert• Proven—enabling reliable performance for over a decade with over 20,000 citationspCR™4-TOPO® TA Vector—Optimized for SequencingThe pCR™4-TOPO® TA vector has a minimized multiple cloning site and, thus, a shorter distance between the sequencing primer sites and the insert site (as little as 33 bp). So sequencing reactions produce less vector sequence and more insert sequence. The pCR™4-TOPO® TA vector has sites for 4 common sequencing primers: M13 forward, M13 reverse, T7, and T3. The kits include an aliquot of each.pCR™4-TOPO® TA Clone Selection and ManipulationThe pCR™4-TOPO® TA vector contains both ampicillin and kanamycin resistance markers and a LacZα-ccdB gene fusion for positive selection and blue/white screening. The vector’s minimized multiple cloning site still includes flankingEcoRI sites for simplified excision of cloned PCR products and a unique Sse8387I site for generation of nested deletions prior to sequencing. T7 and T3 promoters are also present for in vitro transcription.Simplified TOPO®-based CloningUsing 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 transformE. colicompetent cells.Efficient CloningWith up to 95% of clones carrying the desired insert, you can screen less clones and save time and money. The pCR™4-TOPO® TA vector used in this kit comes with 3´T overhangs for efficient ligation of Taq-amplified PCR products, which contain 3´A overhangs.The Most Widely Used Cloning KitWhen 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.Kit Options: TOPO® TA Cloning® Kits for SequencingTOPO® TA Cloning® kits for sequencing can be purchased with a variety of competent cells that deliver different advantages depending upon your needs:• General cloning: TOP10 (Cat. Nos. K4575-J10, K4575-01, K4575-40)• High-efficiency cloning: TOP10 Electrocomp™ cells (Cat. Nos. K4580-01, K4580-40)• General cloning, bacteriophage T1 resistance: DH5α-T1R (Cat. Nos. K4595-01, K4595-40)• Fast growth: Mach1™-T1R chemically competentE. coli(Cat. No. K4530-20)• Provide your own cells (Cat. Nos. 450071, 450030)We also offer a version of the kit that includes a PureLink® Quick Plasmid Miniprep Kit (Cat. No. K4575-02) for use in isolation of clean, sequencing-ready, recombinant plasmid.
