Researchers studying circulating unmethylated and methylated preproinsulin (INS) DNA in type 1 diabetes (T1D) sought to test the differences between subjects with new-onset T1D and controls. DNA was extracted from serum using the ZR Serum DNA Kit and bisulfite converted with the EZ DNA Methylation Kit or the EZ DNA Methylation-Lightning Kit. Droplet digital PCR was used to measure unmethylated and methylated serum levels. The data demonstrated that elevations in both unmethylated and methylated INS DNA occurs in new-onset T1D and that levels of these DNA species change during T1D evolution. The use of methylation levels as potential biomarkers for diabetes may prove to be a novel tool in the near future.Fisher MM, et al. (2015) Elevations in Circulating Methylated and Unmethylated Preproinsulin DNA in New-Onset Type 1 Diabetes. Diabetes. 2015 Nov;64(11):3867-72. doi: 10.2337/db15-0430. Epub 2015 Jul 27.
The EZ DNA Methylation-Lightning Kit was used to bisulfite convert DNA from prefrontal cortex samples of patients with psychiatric diseases. The researchers then used a recently developed bisulfite padlock probe-based approach for ultra-deep mapping of modified cytosines in patients affected or unaffected by major psychosis. Their findings revealed significant epigenetic differences between patients and controls and also identified interesting epigenetic age effects.Pal M et al.

In order to investigate why endogenes are less susceptible to RNA silencing than transgenes, researchers from Germany used the EZ DNA Methylation-Lightning Kit to bisulfite convert DNA from locally and systemically silenced transgenic plant leaves. After amplifying the bisulfite-converted DNA using ZymoTaq polymerase and bisulfite sequencing, the researchers were able to conclude that cDNA transgenes are prone to post-transcriptional gene silencing and RNA-directed DNA methylation while endogene-resembling transgenes are resistant to systemic silencing and DNA methylation.Dadami E. et al. (2014) An endogene-resembling transgene is resistant to DNA methylation and systemic silencing. RNA Biology. 11:7, 1-8
“It combines the speed of the lightning kit with the use of magnetic beads. This allows the full automation of bisulfite treatment. This is what we were looking for.”
