Article Title: Hot Start PCR with heat-activatable primers: a novel approach for improved PCR performance
Article Snippet: Extension of PTE primers by DNA polymerases The ability of Klenow fragment of DNA polymerase I and Taq DNA polymerase to perform template-dependent extension and elongation of the HIV-1 single OXP-modified primers was investigated.

Article Title: Protein Displacement by Herpes Helicase-Primase and the Key Role of UL42 During Helicase-Coupled DNA Synthesis by the Herpes Polymerase
Article Snippet: The absence of any products longer than ~100 nucleotides in assays containing UL30 is not due to either the lower processivity of UL30 relative to UL30-UL42 since UL30 and Klenow Fragment have similar processivity ( ) and Klenow Fragment generates long products.

Article Title: Cleavage of deoxyoxanosine-containing oligodeoxyribonucleotides by bacterial endonuclease V
Article Snippet: Klenow Fragment (3′–5′ exo-) was purchased from New England Biolabs (Beverly, MA).

Article Title: Protein Displacement by Herpes Helicase-Primase and the Key Role of UL42 During Helicase-Coupled DNA Synthesis by the Herpes Polymerase
Article Snippet: Even without ICP8, we found that non-cognate polymerases such as Klenow Fragment and T4 DNA polymerase allow the herpes helicase to more efficiently unwind DNA and allow the synthesis of long products.

Modification:

Article Title: Hot Start PCR with heat-activatable primers: a novel approach for improved PCR performance
Article Snippet: .. Primer extension with Klenow fragment of DNA polymerase Primer extension experiments using large fragment (Klenow) of DNA polymerase I (New England Biolabs) were performed at 25°C using the HIV-1 tat reverse primer (5′-AATACTATGGTCCACACAACTATTGCT-3′) that was unmodified or contained a single OXP modification. ..

DNA Synthesis:

Article Title: 5?CAG and 5?CTG Repeats Create Differential Impediment to the Progression of a Minimal Reconstituted T4 Replisome Depending on the Concentration of dNTPs
Article Snippet: Klenow fragment has weak strand displacement DNA synthesis activity that allowed it to synthesize through the duplex part of the minifork ( , lanes 2 and 5). .. However, contrary to the gp43-gp41 replication couple, DNA synthesis performed by Klenow fragment was not stimulated by gp41 ( , compare lanes 2, 3, 5, and 6). .. Under both conditions (with or without gp41), DNA synthesis was highly distributive as indicated by the numerous pause sites that were clearly visible along the template strand.

Plasmid Preparation:

Article Title: Establishment of conditional vectors for hairpin siRNA knockdowns
Article Snippet: The human U6 promoter was amplified by PCR from the genomic DNA of T24 cells with the primers U6proTop (5′-AGGCAAAACGCACCACGTGACGGAG-3′) and U6proBottomSphI (5′-GCATGCGGTGTTTCGTCCTTTCCACAAGAT-3′), then ligated into a TA cloning vector, pGEM-T Easy (Promega, Madison, WI) (Fig. B). .. The plasmid was then digested with SphI (New England Biolabs, Beverly, MA) and blunted with Klenow fragment (New England Biolabs) (Fig. C). .. Oligo1 [a mixture of two DNA oligomers, DNMTO1F (5′-GGAATGGCAGATGCCAACAGGACGT-3′) and DNMTO1R (5′-CCTGTTGGCATCTGCCATTCC-3′)] was ligated following restriction digestion with AatII (New England Biolabs) (Fig. D).

DNA synthesis activity of minimal reconstituted T4 replisomes across a minifork containing a random sequence. The minifork was prepared with the plasmid p-Empty and thus contains a random sequence to be replicated. <t>gp43,</t> gp41, and gp59 are the DNA polymerase, the helicase and the helicase loader of bacteriophage T4, respectively. (A) Gp43 was incubated with the minifork, alone (lane 2), with gp41 (lanes 3–8) or with gp41 and gp59 (lanes 9–15). The reaction was quenched at various times and the samples were loaded on a denaturing sequencing gel. (a) corresponds to the radiolabelled p821 primer. (b) corresponds to radiolabelled p821 extended by 15 nts up to the base of the 5′ ss tail of the lagging strand template. (c) corresponds to the radiolabelled p821 extended up to the end of the leading strand template after strand displacement DNA synthesis. The (a), (b), and (c) DNAs are also shown in the context of the minifork on the right side of the figure. Major transient intermediate products are indicated by backward arrows. The four sequencing reactions (A, T, C, and G) of the leading strand template of the minifork are shown on the left side of the figure. (B) The minifork was incubated with <t>Klenow</t> fragment alone (lanes 2 and 5), together with gp41 (lanes 3 and 6) or with gp41 and gp59 (lanes 4 and 7) for 20 minutes. The reaction products were resolved on a denaturing sequencing gel. Two amounts of Klenow fragment were tested (1 mU/ μ L, lanes 2–4; 10 mU/ μ L, lanes 5–7). (a) and (c) are as in 3A.
