Engineered reagents preserve performance post-conversion

Libraries prepared with EM-Seq v2 maintain capture efficiency and uniformity. Performance is preserved through downstream workflows specifically for methylation applications, including compatibility with both standard and fast hybridization protocols.

Consistent Methylation Hybridization Capture Performance

EM-Seq v2 libraries processed with Twist hybridization maintain consistent capture efficiency and methylation performance, supporting reliable downstream analysis.

Reproducible Methylation Profiling Across Targets

Consistent detection of differentially methylated regions demonstrates reliable performance across methylation targets, reinforcing reproducibility for downstream methylation analysis.

Consistent library yield across DNA inputs

EM-Seq v2 generates consistent, usable library yields across a wide DNA input range. Reduced dropout at lower inputs supports methylation sequencing when sample availability is limited, while maintaining reliable performance across workflows.

Confident Enzymatic Conversion for Accurate CpG Methylation Calling

EM-Seq v2 delivers robust enzymatic conversion of unmethylated cytosines with consistent CpG call ratios, supporting accurate and reliable methylation analysis while preserving DNA integrity.

Enzymatic Methylation Conversion with EM-Seq v2

EM-Seq V2 uses enzymatic reactions to selectively convert unmethylated cytosines while protecting methylated bases. After amplification, unmethylated sites are read as thymine and methylated sites remain cytosine, enabling accurate methylation analysis without DNA damage.
