Analysis of the methylation of peripheral blood L1 and B1 repeat elements in aging 10

<p>The Net Temperature Shift (NTS) of L1 and B1 repeat elements from peripheral blood (PB) DNA isolated from C57Bl/6 mice at −3, 85, 206, 245 and 299 days following irradiation with sham (white box; <i>n</i> = 7) or 10 mGy (grey box; <i>n</i> = 8) X-rays was assessed by high resolution melt analysis following genomic DNA extraction, bisulphite modification and amplification with L1 and B1 primers.
