Improving Human Health

Epigenetics is the study of how the environment impacts gene expression through DNA modifications that do not alter the genome sequence. Instead, chemical modifications like methylation and acetylation impact several factors, including the folding of chromatin, the binding of histones, the activity of effectors, and the efficacy of promoters. Changes to the epigenome are linked to adverse health effects and are a known underlying risk factor for cancer and other complex diseases. The identification of new epigenetic hallmarks of disease, and the screening for known epigenetic markers, are vital to improving human health.

Twist Bioscience Supports Epigenetic Analysis

A complete methyl-seq workflow including enzymatic conversion capturing up to 15% more methylated cytosines

Custom target enrichment panels for precise, uniform capture of regions of interest involved in epigenetics

Highly uniform libraries of long oligos powering massively parallel functional genomic assays for interrogating gene expression

The Benefits of Enzymatic Conversion in Methyl-seq Workflows

The Benefits of Enzymatic Conversion in Methyl-seq Workflows

While most methods rely on bisulfite conversion of DNA to detect unmethylated cytosines, bisulfite treatment requires high temperatures and a harsh pH that can damage DNA, which is particularly challenging with small sample size or already fragile sample types.

With the Twist Methylation Detection System, you can rescue DNA molecules and experience uniform genomic coverage of more DNA regions by using an enzymatic conversion method. This method allows you to detect up to 15% more methylated cytosines, increasing confidence in methylated-base calls for the study of epigenetics.

Massively Parallel Reporter Assays Elucidate Genetic Factors Powering Gene Expression

Without a detailed understanding of the elements that alter gene expression through epigenetic means, clinically relevant information coded within the growing influx of genetic data will remain undiscovered.

Researchers utilize Massively Parallel Reporter Assays (MPRAs) to interrogate regulatory elements in high throughput.

Twist Long Oligos Power MPRAs

Twist Long Oligos Power MPRAs

Our silicon platform allows us to quickly generate large, accurate and highly uniform MPRA libraries consisting of oligos up to 300 base pairs in length.

These libraries have many advantages:

  • Accurate oligonucleotide synthesis allows you to have confidence in your results and trust that the DNA sequence you design is the sequence you’ll test
  • High uniformity removes bias and screening burden from over and underrepresented elements
  • Access to long oligonucleotide libraries means barcodes can be implemented without sacrificing the sequence of interest
  • Long oligonucleotides also mean more of the natural genetic context can be encoded—enabling more biologically accurate analyses
Epigenetic Analysis: A Promising Tool in Early Cancer Detection

Epigenetic Analysis: A Promising Tool in Early Cancer Detection

DNA methylation is an epigenetic modification that can impact gene expression, and certain abnormal methylation patterns have shown correlation with cancer. While many researchers work toward developing tests to identify multiple cancers from a single blood sample, it remains complex. However, the Twist Targeted Methylation Detection System helps to meet those challenges. With its unique ability to rapidly generate immense numbers of oligonucleotide probes, Twist is able to simplify deconvolution and reduce bias while retaining high sensitivity to low-abundance DNA.

Customer Testimonials

"While working with cfDNA samples, we fell in love with Twist’s targeted methylation solution at first sight! It showed three times better performance, better uniformity, and less off-bait with four-times less cost than other products used previously."
Gahee Park, PhD Research Associate
University of Cambridge
“Twist’s custom panel has enabled us to achieve the enrichment level and precision that we need. When we started with NGS for methylation detection, the maximum we could target was 30 regions, but now with our Custom Panel from Twist, we can capture thousands with better coverage.”
