Accurate sodium bisulfite sequencing in plants.

Heme oxygenase up-regulation under ultraviolet-B radiation is not epigenetically restricted and involves specific stress-related transcriptions factors

Heme oxygenase-1 (HO-1) plays a protective role against oxidative stress in plants. The mechanisms regulating its expression, however, remain unclear. Here we studied the methylation state of a GC rich HO-1 promoter region and the expression of several stress-related transcription factors (TFs) in soybean plants subjected to ultraviolet-B (UV-B) radiation. Genomic DNA and total RNA were isolate...

Whole genome amplification of sodium bisulfite-treated DNA allows the accurate estimate of methylated cytosine density in limited DNA resources.

Sodium bisulfite modification-based fine mapping of methylated cytosines represents the gold standard technique for DNA methylation studies. A major problem with this approach, however is that it results in considerable DNA degradation, and large quantities of genomic DNA material are needed if numerous genomic regions are to be profiled. In this study, we examined whether whole genome amplific...

Partial bisulfite conversion for unique template sequencing

We introduce a new protocol, mutational sequencing or muSeq, which uses sodium bisulfite to randomly deaminate unmethylated cytosines at a fixed and tunable rate. The muSeq protocol marks each initial template molecule with a unique mutation signature that is present in every copy of the template, and in every fragmented copy of a copy. In the sequenced read data, this signature is observed as ...

Neutralization of Excess Formalin by sodium Meta - Bisulfite in combined Anthrax & clostridial vaccine

EpiGnomeTM Methyl-Seq Kit: a novel post–bisulfite conversion library prep method for methylation analysis

Epigenomics is increasingly becoming an important field of research, and the ability to detect and quantify DNA methylation accurately is now critical for numerous fields of study, including disease biology and gene expression. The differential reactivities of methylated and nonmethylated cytosines in DNA with sodium bisulfite forms the basis for their identification in the genome by sequencing...
