    Histone fate after in vitro chromatin resection by the Sgs1-Dna2 pathway. A , native PAGE of a 500-bp DNA fragment harboring a central, 601-positioning sequence reconstituted into mononucleosomes by salt step dialysis at different ratios ( r ) of histone octamers to DNA. Note that the minor nucleosome species is likely to represent a nucleosome assembled on the DNA end. B and C , chromatin resection time course with 3′-radiolabeled chromatin and reactions that contain Mre11-Rad50-Xrs2, Sgs1, Top3-Rmi complex, Dna2, and RPA. C, addition of <t>streptavidin-coated</t> magnetic beads inhibit chromatin resection on one strand. Note the appearance of slower migrating ssDNA. D, analysis of DNA and protein content following magnetic DNA pulldown after chromatin resection. Left panel , radiolabel analysis of DNA before (−) and after (+) resection. One sample was also treated with EcoRI prior to resection and the released DNA was analyzed. Right panel , histone immunoblotting of bead bound ( B ) and unbound ( U ) fractions before and after chromatin resection.

    Article Snippet: The biotinylated ends were captured with 50 μl of streptavidin-coated paramagnetic beads (Dynabeads® M-280 Streptavidin, Invitrogen), and the DNA was then ligated to 60 pmol linker 2 in a 100 μl reaction volume containing 400 U of T4 DNA ligase by incubation at 16°C for 4 h. The precipitate was gently resuspended in 100 μl of 0.15 M NaOH at room temperature for 10 min and eluted with 30 μl 10 mM Tris–Cl (pH 8.0).

    Schematic drawing of the PrASE procedures. A nested multiplex PCR amplification is performed with biotinylated inner PCR primers, generating short PCR products. The biotinylated PCR products are immobilized to streptavidin-coated magnetic beads, and ssDNA is generated by alkali elution of the non-biotinylated strand followed by annealing of ASE primers to the immobilized DNA strands. A washing step, where unannealed extension primers are removed, is then followed by PrASE with Cy5-labeled dCTPs and dUTPs. The last steps involve removal of unreacted nucleotides and PrASE enzymes, release of PrASE products by alkali elution and hybridization to tag microarrays. All procedures except the last step of hybridization to tag arrays are automated.
