Description

Description

These kits include everything necessary to clone and select recombinant vectors containing your PCR fragment of choice.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.
pCR4-TOPO TA Vector: Optimized for Sequencing
We have removed much of the multiple cloning site from the pCR4-TOPO TA vector to shorten the distance between sequencing primer sites and the insert site to as little as 33 bp. This means sequencing reactions give less vector sequence and more insert sequence. The pCR4-TOPO TA vector has sites for four common sequencing primers: M13 forward, M13 reverse, T7, and T3. The kits include an aliquot of each.
pCR4-TOPO TA Clone Selection and Manipulation
The pCR4-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 flanking EcoRI 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 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 with the providedE. coli competent cells.
Efficient Cloning
With up to 95% of clones carrying the desired insert, you can screen less clones to help you save time and money. The pCR4-TOPO TA vector used in this kit comes with 3'T overhangs for efficient ligation of Taq-amplified PCR products with 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 Sequencing Kit Options
The TOPO TA Cloning Kit for Sequencing can be purchased with a variety of competent cells that deliver different advantages depending on what your needs are:

  • 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 Competent E. Coli (Cat. No. K4530-20)
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 is also available.

  • 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 three steps and in as little as 5 minutes hands-on time
  • Efficient: Achieve up to 95% clones with correct insert
  • Proven: Reliable performance for over a decade with over 4,000 citations
