    A blend of Taq–Phusion polymerases improves selective poly(A) amplification of cDNA and reduces AL1 primer requirements. Cells were obtained by LCM from a human breast biopsy and split into 10-cell equivalent amplification replicates. ( A ) Poly(A) PCR was performed with 15 µg of AL1 primer with Taq alone (10 units), Phusion alone (4 units) or Taq/Phusion combination (3.75 units/1.5 units). ( B ) Poly(A) PCR was performed with either 25, 5, 2.5, or 0.5 µg of AL1 primer and the Taq–Phusion blend from (A). Above—Relative abundance for the indicated genes and preamplification conditions was measured by quantitative PCR (qPCR). Data are shown as the median inverse quantification cycle (40–Cq) ± range from n = 3 amplification replicates and were analysed by two-way (A) or one-way (B) ANOVA with replication. Below—Preamplifications were analysed by agarose gel electrophoresis to separate poly(A)-amplified cDNA from nonspecific, low molecular-weight concatemer (n.s.). Qualitatively similar results were obtained separately three times. Lanes were cropped by poly(A) PCR cycles for display but were electrophoresed on the same agarose gel and processed identically. The uncropped image is shown in Supplementary Fig. S13A .

(2) The hybrid primers are color coded, blue for sequence complementary to the plasmid, and green for the insert. The length of the primers can be adjusted by clicking on the arrow buttons if the user wishes to alter the annealing temperature. (3) If the insert site needs to be adjusted, the user can use the provided arrow buttons. (4) The secondary PCR conditions are optimized for iProof or Phusion as the polymerase, so the user should follow manufacturer’s instructions if using another high fidelity enzyme. ‘Insert’ refers to the mega-primer purified from the primary PCR reaction. (5) The entire sequence of the new plasmid is output, with insert in green and parental plasmid in blue. (6) The plasmid map can be drawn by specifying the positions of markers manually, or by auto-finding common features. Restriction enzyme cut sites can also be specified or automatically identified. If desired, the plasmid can be exported as a genbank file. (7) All projects are automatically saved, but making changes to the output page will activate the save button so those changes can be uploaded to the database. If the user has registered an account to access the plasmid management system, the save button will attach the project to their profile. (8) After the project has been completed and sent for sequencing, the sequencing results can be copied into a popup window for BLAST2 sequence alignment.

    Article Title: RF-Cloning.org: an online tool for the design of restriction-free cloning projects
    Article Snippet: RECOMMENDED RF-CLONING PROTOCOL By default, the starting hybrid primers will be at least 40 bp long with an annealing temperature of at least 55°C for the primary PCR (amplification of insert) and at least 60°C for the secondary PCR (extension around the plasmid). .. High-fidelity DNA polymerase should be used for all PCR reactions, and it has been our experience that iProof (BioRad, Hercules, CA, USA) and Phusion (New England Biolabs, Ipswich, MA, USA) produce consistent results. .. To generate the mega-primer, use a standard 50 μl PCR reaction (1× PCR buffer, 200 μM dNTP, 500 nM of each primer, 1 U polymerase, user defined amount of starting template) and cycle 30–35 times with the RF-Cloning.org recommended annealing temperature, followed by product purification (e.g. by gel extraction).

    Article Title: High-throughput mutagenesis using a two-fragment PCR approach
    Article Snippet: When using KOD Hot Start Master Mix, the following thermocycling setup was used: Initial denaturation at 95 °C for 2 min, followed by 20 step-down thermal cycles, each comprising denaturation at 95 °C for 20 s, annealing from 65 °C down to 55.5 °C for 10 s (0.5 °C decrement per cycle), and elongation at 70 °C for at the appropriate time (up to 135 s), then 5 thermal cycles with the constant annealing temperature (denaturation at 95 °C for 20 s, annealing at 62.5 °C for 10 s, elongation at 70 °C with the same time period as used in the step-down cycles), completed with a hold at 10 °C. .. For truncations of the AtETR1 and LeETR1 plasmids by the two-fragment approach, a slightly different PCR protocol was used: 20 μL PCR mixture prepared with nuclease-free water (Cell Signaling Technology) contained 1 ng DNA template, 500 nM each primer, 200 μM each dNTP (deoxynucleoside triphosphate; NEB), 0.4 U μL−1 Phusion High-Fidelity DNA Polymerase (NEB), and either 1× Phusion buffer HF (NEB) or 3% (v/v) DMSO (NEB) with 1× Phusion buffer GC (NEB). .. Also, PCR thermocycling described above was modified in case of the ETR1 plasmids to have: (1) 11 step-down cycles with annealing starting from 65 °C down to 60 °C (i.e. decreasing by 0.5 °C in each subsequent cycle); (2) elongation time of at least 30 s per kbp of the target product (up to 200 s for the longest PCR products); and (3) final elongation time of 5 min.

    Article Title: Restriction enzyme-free mutagenesis via the light regulation of DNA polymerization
    Article Snippet: It is important to note that the selection of primers is key, and for some sequences, longer hybridization arms are required (see GFP deletion in ), which in turn requires additional caging groups to prevent undesirable hybridization during the PCR (see ‘Results and Discussion’ section). .. The forward and reverse primers (5 μl each of a 10 μM solution), the pGFPuv template (1 μl of a 0.1 ng/μl solution), dNTPs (2 μl each of a 1 mM solution), Phusion GC Buffer (5 μl of a 10× stock, New England Biolabs), Phusion DNA Polymerase (1 μl, two units) and dH2 O (31 μl) were mixed and subjected to the following PCR program: 95°C (2 min), followed by 40 cycles of 95°C (30 s), 40°C (60 s) and 72°C (3.3 min), with a final extension at 72°C (2 min). .. An identical PCR reaction was then repeated, using 5 μl of the previous reaction as the template, followed by purification with a PCR cleanup kit (Promega).
