    New England Biolabs dnase i buffer
    The β-gt can specifically modify 5hmC residues at a high efficiency. ( a ) Oligonucleotides that were either incubated in the presence or absence of the β-gt were digested with Taq I, treated with alkaline phosphatase, 5′-end labeled using T4 polynucleotide kinase and digested to 5′-mononucleotides using <t>DNase</t> I and Snake Venom Phosphodiesterase. Radiolabeled mononucleotides were analyzed by two-dimensional TLC. C, 3′-deoxyribocytosine-5′-monophosphate; T, 3′-deoxyribothymidine-5′-monophosphate; 5meC, 3′-deoxyribo-N5-methylcytosine-5′-monophosphate; 5hmC, 3′-deoxyribo-N5-hydroxymethylcytosine-5′-monophosphate. ( b ) HPLC coupled to tandem mass spectrometry was used to measure the efficiency of the β-gt reaction. Substrates analyzed were 2.7 kb linear PCR products of pUC18: the dC substrate contained only cytosine residues; the 5meC substrate was created by methylating the CpG dinucleotide of the cytosine substrate; the 5hmC substrate was created by using d5hmC in place of dCTP in the PCR reactions; the β-glu-5hmC substrate was created by incubating the 5hmC substrate with the β-gt in the presence of UDP-glucose.

    The β-gt can specifically modify 5hmC residues at a high efficiency. ( a ) Oligonucleotides that were either incubated in the presence or absence of the β-gt were digested with Taq I, treated with alkaline phosphatase, 5′-end labeled using T4 polynucleotide kinase and digested to 5′-mononucleotides using DNase I and Snake Venom Phosphodiesterase. Radiolabeled mononucleotides were analyzed by two-dimensional TLC. C, 3′-deoxyribocytosine-5′-monophosphate; T, 3′-deoxyribothymidine-5′-monophosphate; 5meC, 3′-deoxyribo-N5-methylcytosine-5′-monophosphate; 5hmC, 3′-deoxyribo-N5-hydroxymethylcytosine-5′-monophosphate. ( b ) HPLC coupled to tandem mass spectrometry was used to measure the efficiency of the β-gt reaction. Substrates analyzed were 2.7 kb linear PCR products of pUC18: the dC substrate contained only cytosine residues; the 5meC substrate was created by methylating the CpG dinucleotide of the cytosine substrate; the 5hmC substrate was created by using d5hmC in place of dCTP in the PCR reactions; the β-glu-5hmC substrate was created by incubating the 5hmC substrate with the β-gt in the presence of UDP-glucose. Control DNA was prepared from salmon sperm. LC/MS/MS chromatograms of the cytosine residues from each of the substrates are presented. Abbreviations: dC, 3′-deoxyribocytosine; 5me(dC), 3′-deoxyribo-N5-methylcytosine; 5hm(dC), 3′-deoxyribo-N5-hydroxymethylcytosine; 5-glu-hm(dC), 3′-deoxyribo-N5-(β- d -glucosyl(hydroxymethyl))cytosine.

    Article Snippet: Reaction mixture was first heated at 95°C for 5 min. 35 cycles were then carried out with the following parameters: denaturing at 95°C for 30 s, annealing at 60°C for 30 s, extension at 72°C for 40 s. Reaction was finished with a final extension at 72°C for 5 min. PCR products were then denatured at 95°C for 5 min, annealed by cooling down at room temperature for 30 min, and treated with T7 endonuclease I (NEB, M0302L) at 37°C for 15 min. Digested DNA was separated on a 3% agarose gel.

Each PCR product was amplified from genomic DNA extracted from a hind leg of a sexually matured drone, and then treated with T7 endonuclease I. Magenta and blue arrowheads indicate the expected band size of the PCR products digested by T7 endonuclease I at the sgRNA target site (#3 and #10 in Experiment 3, #6 in Experiment 5) and at repeated A region, respectively. ( B ) Sequences around the sgRNA target site of mutant drones in ( A ). Orange dashes indicate detected deletions.
