Hieff Superfast DNA Methylation Bisulfite Kit

The Hieff Superfast DNA Methylation Bisulfite Kit (Column-based) rapidly converts unmethylated cytosines in DNA samples to uracil, while leaving methylated cytosines unchanged. During high-temperature bisulfite treatment, double-stranded DNA denatures into single strands. In the presence of HSO3-, cytosine residues undergo deamination and are converted into uracil, with methylated cytosines remaining unaltered. In subsequent PCR amplification, uracil is replaced by thymine (T). The conversion process takes only 5 minutes, accommodating DNA input ranging from 100 pg to 2 μg, and achieves a conversion efficiency of ≥99% for unmethylated cytosines. The converted DNA is suitable for downstream applications such as PCR amplification and NGS sequencing.
