Scientific Reports 6: Article number: 28506; published online: 24 June 2016; updated: 08 December 2016.

In this Article the Authors incorrectly stated that they had developed a novel method termed bisulfite amplicon sequencing (BSAS). The method was reported by Masser et al. (reference 18 in the Article). Thus the following sentence (which appears verbatim in ref 18):

“By combining the benefits of bisulfite conversion, targeted amplification, tagmentation-based library construction, and NGS, we have developed a novel method termed bisulfite amplicon sequencing (BSAS) for targeted digital high accuracy quantitation of DNA methylation18”.

should read:

“In a previous study, Masser et al. developed a method termed bisulfite amplicon sequencing (BSAS) for targeted digital high accuracy quantitation of DNA methylation by combining the benefits of bisulfite conversion, targeted amplification, tagmentation-based library construction, and NGS18”.

The following sections in “Materials and Methods” failed to appropriately cite the protocols followed:

“DNA bisulfite conversion and bisulfite specific PCR”.

should read:

“DNA bisulfite conversion and bisulfite specific PCR13”.

“NGS library preparation and sequencing”.

should read:

“NGS library preparation and sequencing18”.

“Real-time PCR analysis”.

should read:

“Real-time PCR analysis13”.

An additional reference is listed below as reference 1 and should appear in the text as below:

“NGS data analysis and digital methylation quantitation”.

should read:

“NGS data analysis and digital methylation quantitation1”.

The Authors apologize for these errors.
