    New England Biolabs t4 ligase
    Schematic overview of the QL cloning procedure. An envelope gene or an envelope library is amplified with primers to introduce flanking Esp3I restriction sites enabling the generation of a 5′ NcoI and a 3′ Xho sitey (A; top). The envelope gene or an envelope library is incubated together with pQL9/11 in a one-tube reaction with Esp3I and <t>T4-Ligase.</t> Compatible “sticky-ends” (equally colored) can be ligated successfully, direct proper orientation and mediating resistance for further cleavage (A). Following transformation of CcdB sensitive bacteria, only recipients bearing a plasmid without CcdB are able to form colonies in the presence of ampicillin. (B) The lentiviral vector construct pQL9 comprises (i) 5′LTR (Long terminal repeat), (ii) EF1α (human promotor), (iii) GFP (marker gene), (iv) an IRES (internal ribosome entry site), (v) a CcdB positive selection marker [58] , and (vi) a 3′LTR sequence.

    Agarose gel electrophoresis analysis of <t>PCR</t> fragments multiplied by <t>Phusion</t> High-Fidelity PCR Master Mix with HF Buffer and Phusion High-Fidelity PCR Master Mix with GC Buffer. Analysed PCRs are labelled as the mutated residue and the letter indicating whether the fragment is multiplied by mutation-specific forward (F) or reverse (R) primer. Expected PCR fragments are between 3000 and 4000 bp long. While using the PCR master mix with GC buffer gave expected fragments in all shown cases, using the Phusion High-Fidelity polymerase with HF buffer failed to multiply four fragments.

    New England Biolabs t4 ligase buffer
    Strategy for constructing nicked heteroduplexes. A mismatch-containing oligonucleotide duplex (Fig. 1) is ligated into a template plasmid molecule (1). Linearization of the plasmid (2) in the presence of the heteroduplex oligo, <t>T4</t> ligase and restriction enzyme ( Bam HI) allows ligation of the small fragments onto each DNA end as a dead-end complex (3), because the Bam HI site is eliminated. Re-ligation of Bam HI-generated plasmid ends yields a molecule competent for a second digestion, returning them to the substrate pool. In the next step, digestion with Eco RI removes one ligation product and generates a ligation-competent DNA end (4). After removal of the smaller fragment, an intramolecular ligation reaction generates the nicked circular product (5). Unwanted linear molecules are removed by digestion with Exonuclease V (Materials and Methods).

    Figure Lengend Snippet: Construction outline of the MCP tac s promoter clusters . Fragment 5CP tac s with the flanking sequence was amplified by PCR with p5TG as the template. Fragment 1 was generated by digesting fragment 5CP tac s with BamH I. Fragment 2 was digested from fragment 5CP tac s with BamH I and Hind III. Fragment 3 was linearized from the plasmid p5TG with Hind III. Then, the three fragments were assembled together under the action of T5 exonuclease, Phusion DNA polymerase and Taq DNA ligase in the isothermal process.

    Article Snippet: Then, fragment 1, 2 and 3 were assembled together in vitro under the action of T5 exonuclease (Epicentre), Phusion Hot Start DNA Polymerase (New England Biolabs (NEB)) and Taq DNA ligase (NEB) at 50°C for 15 min.
