Bisulfite Conversion Overview

Zymo Research offers the fastest, most trusted, and most cited products in the industry for bisulfite conversion of methylated DNA.

Bisulfite Conversion - Cytosine to Uracil

Bisulfite conversion, also known as bisulfite treatment, is used to deaminate unmethylated cytosine to produce uracil in DNA and is considered the "gold standard" for downstream applications to assess DNA methylation status. Methylated cytosines are protected from the conversion to uracil, allowing the use of direct sequencing to determine the locations of unmethylated cytosines and 5-methylcytosines at single-nucleotide resolution. Zymo Research offers the fastest, most cited, and most trusted products in the industry for bisulfite conversion of methylated DNA.
