    S1 nuclease converts supercoiled plasmid <t>DNA</t> to nicked circular and linear forms through digestion at a variety of locations in the plasmid. (A) Two μg of supercoiled pRH04.152-rbsB was incubated at 22°C (top) or 37°C (bottom) with different amounts of S1 nuclease for different lengths of time and then analyzed by agarose gel electrophoresis. The sixth and seventh lanes contain undigested supercoiled control and SpeI-digested linear control, respectively. The band that runs slower than the linear band was presumed to correspond to nicked circular plasmid. In the thirteenth lane, after the DNA was digested with 10 units for 24 hours an additional 10 units of S1 nuclease was added and the DNA was incubated for an additional hour. The first and last lanes contain the λDNA/HindIII molecular weight standards. (B) Plasmids with or without the f1 origin (pDIMC8-pfMBP and pRH04-pfMBP, respectively) were incubated with or without S1 nuclease, followed by incubation with or without NcoI, <t>EagI,</t> and SacII and then analyzed by agarose gel electrophoresis. (C) Plasmids with or without the f1 origin (pDIMC8-rbsb and pRH04-rbsb, respectively) were incubated with S1 nuclease or DNaseI, followed by incubation with XmnI and analyzed by agarose gel electrophoresis.

    Maternal methylation of a novel DMR at the Actn1 gene in diverse mouse tissues. A) A detailed map of the novel maternal Actn 1 DMR is shown in the lower part. The diagram directly above shows the design for the MS-RFLP and bisulfite sequencing validation assays. Also included in this diagram are the locations of the methylation-sensitive enzyme restriction sites tested with MS-RFLP ( BsaAI, EagI and HpaII) , the strain-specific cut sites ( AhdI (present in 129S1 but not in PWK, due to SNP rs32640406) and StyI (present in PWK but not in 129S1, due to SNP rs32640412)), and the strain-specific resulting restriction fragments (see Methods). B) MS-RFLP results of four mouse liver samples. The matrix above the gel shows the different conditions for each individual lane. The plus sign (+) indicates addition, while the minus sign (−) indicated no addition of each corresponding endonuclease. C) Percent maternal methylation of an individual CpG (targeted by the BsaAI endonuclease) within different tissues. Circles represent individual (PWK×129S1)F 1 mice, while triangles represent individual (129S1×PWK)F 1 mice. Horizontal bars represent percent maternal methylation averages.

    CDKN2A gene and its expression in the presence or absence of the c.53C > T mutation. (a) Schematic representation of the genomic structure and transcripts of the CDKN2A gene locus with c.53C > T mutation and primer locations. The exons are shown as rectangles and primers as arrows. Primers 1 and 5 were used for RFLP analysis (see figure c), primers 3 and 4 were used for ddPCR analysis (see figure b), and primers 2 and 5 were used for additional ddPCR analysis (see Figure S1 ). An <t>EagI</t> restriction site is present in a wild‐type carrier, but absent in the individual with the c.53C > T mutation. The size of the locus, transcripts, exons, and introns is not shown to scale. Of note, the size of the intron between exon 1a and exon 2 is approximately 3.5 kb. (b) Comparison of CDKN2A transcript copies after normalization to GAPDH in early and late passage primary fibroblasts from young and advanced age healthy subjects without the c.53C > T mutation and in early and late passage primary fibroblasts from the XPA patient where the c.53C > T mutation is present at an allele frequency of 55.3% in the late passage. Primers 3 and 4 were used for this ddPCR analysis.

Primers 1 and 5 were first used to amplify the cDNA followed by digestion with restriction enzyme EagI (indicated by +).

    Article Snippet: To determine the physical map of pELF1, the excised plugs containing pELF1 DNAs were separately digested at 37°C for 24 h with 20 U of Sal I-HF (New England BioLabs, Ipswich, MA, United States), at 25°C for 24 h with 100 U of Sma I (New England BioLabs), at 37°C for 24 h with 150 U of Eag I-HF (New England BioLabs), and at 37°C for 24 h with 150 U of Sac I-HF (New England BioLabs).

    Techniques: Produced

    PFGE of the restriction fragments of pELF1 with proteinase K treatment. Lanes: Low Range PFG Marker; proteinase K-treatment only; proteinase K-treated Sal I digests; proteinase K-treated Sma I digests; proteinase K-treated Eag I digests. N. D., not digested.

    CDKN2A gene and its expression in the presence or absence of the c.53C > T mutation. (a) Schematic representation of the genomic structure and transcripts of the CDKN2A gene locus with c.53C > T mutation and primer locations. The exons are shown as rectangles and primers as arrows. Primers 1 and 5 were used for RFLP analysis (see figure c), primers 3 and 4 were used for ddPCR analysis (see figure b), and primers 2 and 5 were used for additional ddPCR analysis (see Figure S1 ). An EagI restriction site is present in a wild‐type carrier, but absent in the individual with the c.53C > T mutation. The size of the locus, transcripts, exons, and introns is not shown to scale. Of note, the size of the intron between exon 1a and exon 2 is approximately 3.5 kb. (b) Comparison of CDKN2A transcript copies after normalization to GAPDH in early and late passage primary fibroblasts from young and advanced age healthy subjects without the c.53C > T mutation and in early and late passage primary fibroblasts from the XPA patient where the c.53C > T mutation is present at an allele frequency of 55.3% in the late passage. Primers 3 and 4 were used for this ddPCR analysis. (c) RFLP analysis of CDKN2A transcript in early and late passage primary fibroblasts from young age healthy and advanced age healthy subjects without the c.53C > T mutation and in early and late passage primary fibroblasts from XPA patient where the c.53C > T mutation is present at an allele frequency of 55.3% in the late passage only. Primers 1 and 5 were first used to amplify the cDNA followed by digestion with restriction enzyme EagI (indicated by +). Part of the amplified sample was used as an undigested control (indicated by −). Undigested PCR product is 658 bp in size, while digested fragments are 274 bp and 384 bp in size
