  • TOOLS UltraFast PCR Cloning Kit

    TOOLS UltraFast PCR Cloning Kit

    TOOLS UltraFast PCR cloning kit is designed for fast and directional cloning of the single or multiple DNA into any vector at any site, regardless of DNA fragment end compatibility. This kit is applicable for efficient clone of fragments of 50 bp - 10 kb. The vector is linearized at the cloning site. A small sequence overlapped with each end of the cloning site is added onto the insert through PCR. The insert and the linearized vector, with overlapped sequences of 15 bp - 20 bp on both 5’- and 3’-end, respectively, are mixed in an appropriate ratio and incubated with recombinase 2X UltraFast Mix at 50°C for 5 - 15 min. This kit is a novel cloning kit, applicable for homologous recombination with 1 - 5 fragments. The Kit is independent of DNA ligase, significantly reducing the self-ligated colonies. The enhanced recombinase and highly optimized buffer included in 2X UltraFast Mix significantly improve the recombination efficiency and the tolerance to impurities. pFAST vector is compatible with most PCR products, enabling the specific PCR products to be used directly for recombination without any treatments, which significantly simplify the procedure.

  • TOOLStart Blue Staining Reagent

    TOOLStart Blue Staining Reagent

    TOOLStart Blue Staining Reagent is an enhanced protein stain based on Coomassie dye that offers unsurpassed sensitivity and rapid band visualization. TOOLStart Blue Staining Reagent is a rapid, sensitive, and odorless. TOOLS Coomassie Blue detects the proteins for as few as 50 ng, and the protein bands are visible in just 3-5 minutes, with maximal staining achieved in 2-3 hours. TOOLStart Blue Staining Reagent is supplied in a ready-to-use form that is capable of being added directly to protein gels after electrophoresis without the need to wash, fix or de-stain.

  • 2x Ultra Hi-Fi PCR Master Mix

    2x Ultra Hi-Fi PCR Master Mix

    TOOLS 2× Ultra Hi-Fi PCR Master Mix is is a new generation superior enzyme based on Ultra Hi-Fi DNA Polymerase for robust PCR with higher fidelity. The unique extension factor, specificity-promoting factors and plateau-inhibiting factor newly added to Ultra Hi-Fi greatly improve its long-fragment amplification ability, specificity, and PCR yield. Ultra Hi-Fi is capable of amplifying long fragments such as 40 kb λ DNA, 40 kb plasmid DNA, 20 kb genomic DNA and 10 kb cDNA. The amplification error rate of P Ultra Hi-Fi is 53-fold lower than that of conventional Taq and 6-fold lower than that of Pfu. In addition, Ultra Hi-Fi has a good resistance to PCR inhibitors and can be used for direct PCR amplifications of bacteria, fungi, plant tissues, animal tissues, and even whole blood samples. P Ultra Hi-Fi contains two monoclonal antibodies inhibiting the 5 ́→3 ́ polymerase activity and 3 ́→5 ́ exonuclease activity at room temperature, which enable Ultra Hi-Fi to perform greatly-specific Hot-Start PCRs. 2× Ultra Hi-Fi PCR MasterMix contains 2× Ultra Hi-Fi Super-Fidelity DNA Polymerase, dNTP, and an optimized buffer system. The amplification can start only with the addition of primer and template, thereby easing PCR setup and improving reproducibility. Protective agents in this product are capable of repeated freeze-thaw cycles.
