Taq DNA polymerase

Supplier: G-Biosciences
Description: <i>Taq</i> DNA Polymerase is a highly thermostable recombinant DNA polymerase derived from the thermophile <i>Thermus aquaticus</i>. The molecular weight of the recombinant protein is 94 kD. The <i>Taq</i> Polymerase is able to amplify DNA up to 5 kb with an elongation velocity of 0,9 to 1,2 kb/min at 70 to 75 °C. The error rate of this <i>Taq</i> Polymerase is ~2,2×10⁻⁵ nucleotide⁻¹ cycle⁻¹. <i>Taq</i> DNA polymerase catalyses the 5’→3’ synthesis of DNA. The enzyme has no detectable 3’→5’ proofreading exonuclease activity, and possesses low 5’→3’ exonuclease activity, which results in a 3’-dA overhang on the PCR product

Bacterial Protein Extraction Kits, B-PER™

Supplier: Thermo Fisher Scientific
Description: B-PER® Bacterial Protein Extraction Reagents are designed to extract soluble protein from bacterial cells. The B-PER® Bacterial Protein Extraction Kit eliminates the need for harsh mechanical procedures, like sonication. The easy-to-use cell lysis solution uses mild non-ionic detergents to disrupt cells and solubilise proteins without denaturation. Enzyme supplements such as DNase I and Lysozyme allow for improved yield of large molecular weight proteins which are difficult to purify. B-PER® is also compatible with downstream protein purification methods such as GST purification and His-tagged immobilised metal affinity chromatography (IMAC).

Pfu DNA polymerase

Supplier: G-Biosciences
Description: <i>Pfu</i> DNA Polymerase, derived from the hyperthermophilic archae <i>Pyrococcus furiosus</i>, has superior thermostability and proofreading properties compared to other thermostable polymerases. It has a molecular weight of 90 kDa and can amplify DNA targets up to 2 kb. The elongation velocity is 0,2~0,4 kb/min (70~75 °C). <i>Pfu</i> DNA Polymerase possesses 3' to 5' exonuclease proofreading activity that enables the polymerase to correct nucleotide misincorporation errors. This means that<i> Pfu</i> DNA Polymerase-generated PCR fragments will have fewer errors than <i>Taq</i>-generated PCR inserts. Using <i>Pfu</i> DNA Polymerase results in blunt-ended PCR products, which are ideal for cloning into blunt-ended vectors. <i>Pfu</i> DNA Polymerase is superior for techniques that require high-fidelity DNA synthesis.

Cyanine 3-dUTP

Catalog Number: (ENZOENZ42501)
Supplier: ENZO LIFE SCIENCES
Description: Cyanine 3-dUTP can replace TTP in reactions in which it serves as a substrate for E. coli DNA polymerase (holoenzyme and Klenow fragment), T4 and Taq DNA polymerases, reverse transcriptase (from AMV and M-MuLV) and terminal transferase. Fluorescently labeled probes can be prepared with this fluorescent nucleotide by a variety of methods including nick translation, cDNA labeling and 3’-end labeling. Probes generated by these methods are suitable for use for the identification of specific sequences by in situ hybridization procedures on fixed cells and tissues by direct fluorescence detection. Cyanine 3-dUTP can also be used for multicolor fluorescence labeling.

Chemicon® ReBlot Plus Mild Antibody Stripping Solution, 10X

Catalog Number: (MILF2502)
Supplier: Merck
Description: Western blotting is a commonly used technique for studying protein function and localisation. Typically, protein samples are electro-phoresed on SDS-page and transferred to a membrane such as nitrocellulose or nylon, where they are probed with specific antibodies. Unlike nucleic acid based technologies, which allow reuse of southern and northern blots, it has been difficult to reuse western blots.

T4 UvsX DNA Recombinase

Supplier: G-Biosciences
Description: T4 UvsX DNA recombinase mediates DNA strand exchange between homologous chromosomes. The protein forms a right-handed nucleoprotein complex on single ssDNA called the presynaptic filament that can search for homology in duplex DNA and pair the recombining DNA molecules to form a DNA joint molecule. This process is aided by ssDNA binding proteins and recombination mediators. The filament is then elongated by DNA polymerase with the newly synthesised strand displacing the old strand. The newly synthesised duplex DNA can then act as a template for the next cycle to achieve exponential amplification of dsDNA. <i>E.coli</i> cells expressing recombinant T4 UvsX gene.

PerfeCTa® qPCR FastMix™ reaction mixes

Supplier: Quantabio
Description: FastMixes include buffers and stabilisers optimised for maximum PCR efficiency, reproducibility, and sensitivity with TaqMan® and TaqMan® MGB probe chemistries. A key component of PerfeCTa® qPCR FastMixes is AccuFast™ <i>Taq</i> DNA polymerase that enables instant activation and rapid polymerisation kinetics. Upon heat activation (20 seconds at 95 °C), the antibodies irreversibly denature releasing fully active, unmodified <i>Taq</i> DNA polymerase. This promotes specific and efficient primer extension with the convenience of room temperature reaction assembly. FastMixes deliver maximum PCR efficiency, sensitivity, specificity, and a robust fluorescent signal with either fast or conventional cycling conditions.

Taq DNA polymerase (native, with BSA)

Catalog Number: (EP0072)
Supplier: Thermo Fisher Scientific
Description: <i>Taq</i> DNA Polymerase is a highly thermostable DNA polymerase from the thermophilic bacterium <i>Thermus aquaticus</i>. The enzyme catalyses 5'→3' synthesis of DNA, has no detectable 3'→5' exonuclease (proofreading) activity and possesses low 5'→3' exonuclease activity. In addition, <i>Taq</i> DNA polymerase exhibits deoxynucleotidyl transferase activity, which frequently results in the addition of extra adenines at the 3'-end of PCR products. Native <i>Taq</i> DNA polymerase is preferred for amplification of bacterial DNA sequences homologous to those found in <i>E.coli</i>. Native<i> Taq</i> DNA polymerase stabilised with BSA is often the best choice when amplifying DNA samples of lower purity, e.g. genomic DNA from mouse tail.
