Sage Science

Sage Science develops sample prep technologies for life science research. We focus on electrophoretic approaches that improve and automate high-value steps in Next Gen sequencing workflows. Sage sells the Pippin™ line of DNA size selection instruments, which are widely used for DNA, RNA, and ChIP-seq library construction for short-read sequencing. Our systems are also used for preparing high molecular weight DNA for 3rd generation, long-range genomics platforms. Our products are manufactured at our headquarters in Beverly, Massachusetts, USA.

Use ddRAD-seq to Study Non-Model Organisms

Reduced-representation genome sequencing has been one of the most important advances in the last several years for enabling massively parallel genotyping of organisms for which there is no reference-grade genome assembly. An implementation of the approach known as ddRAD-seq, first conceived in the Hoekstra lab at Harvard, has been widely adopted by the plant and…

NGS Target Enrichment Strategies

Next-generation sequencing (NGS) has ushered in a new era of understanding of both the inner workings and the function of the genome. NGS allows researchers to look at traits—including diseases—that are linked to differences or mutations in an individual’s genes. Since only about 1% of the human genome constitutes genes that code for proteins, several…

ChIP-seq Workflows Run Best with Automated DNA Size Selection

Chromatin immunoprecipitation sequencing, better known as ChIP-seq, is a massively parallel approach for understanding the interactions between proteins and DNA. This is especially important for determining the activity of transcription factors, which is why it’s frequently used to learn about the complicated series of biological steps leading to cancer. It’s also key to many epigenetic…

Generating High-Quality Genome Assemblies from Metagenomic Sequencing

The decreasing costs in genomic sequencing over the past decade have inspired researchers to apply shotgun next-generation sequencing to entire microbial communities. While the reads generated typically cannot be assembled cleanly into individual genomes, there is often enough information produced to identify most microbes present in the population. However, this approach lacks sufficient resolution to…

CRISPR-Inspired Method Targets Large, Repetitive DNA Elements

Target capture through PCR has been a mainstay in genomics for years, but scientists working on especially repetitive, poorly characterized, or rapidly evolving regions continue to struggle to fish out those stretches of DNA for further study. However, whole genome sequencing, the only other alternative for these regions, can force researchers to pay for much…

NGS-Based HLA Typing Delivers More Comprehensive Information

Used for matching organ transplants to donors and other applications, human leukocyte antigen (HLA) typing is rapidly shifting from older methods to NGS technologies. This is a major step forward, as more complete views of the highly polymorphic HLA genes provide a deeper understanding of how a person’s natural genetic variation might affect transplant matches…

Size-Selection Is Essential for Cell-Free DNA Studies

Advances in using cell-free DNA (cfDNA) to glean clinically meaningful information for a patient have been stunning. For the most part, these research studies (or downstream diagnostic tests) isolate fetal DNA in the mother’s blood or tumor-derived DNA from the background of healthy DNA in the bloodstream. Typically known as liquid biopsies, these minimally invasive…

How Does Automated Electrophoresis Perform DNA Size Selection?

Anytime lab processes get automated by a sophisticated scientific instrument, there can be a “black box” effect, leading users to wonder what’s going on in there. For DNA electrophoresis, it’s no different. It’s easy to see what’s happening in a manual gel, but the automated gel-based DNA size selection platforms can be more mysterious. Automated…

DNA Sizing Tutorial: When to Use Manual Gels, Beads, and More

There are several methods for size-selecting DNA fragments prior to sequencing. How do you choose which is best? Here’s a look at various options, plus considerations to help you determine when to use each one. Manual Gels Virtually every student in a biology lab knows how to prepare and cut a manual gel—but their ubiquity…

For Better NGS Assemblies, Use More Precise DNA Size Selection

It may not be intuitive that a sample preparation step like DNA size selection would have a significant impact on downstream data analysis, but NGS users have proven that it does. Indeed, the precision of your size selection (or lack thereof) can make or break a genome assembly. Consider the alignment challenge for paired-end reads:…

The Art of Size Selection for Small RNAs

Size selection is a critical step in NGS pipelines, but may be most challenging for studies of small RNAs. The concept behind size selection is simple: separate a sheared DNA or cDNA sample by fragment size, and then use the resulting sizes to remove unwanted fragments. This is a tried-and-true way to get rid of…

For Long-Read Sequencers, Size Selection Is Key

It took scientists a little while to warm up to long-read sequencing, but now you couldn’t pry most of them away from their sequencers with a crowbar. Long reads — we’re talking 10,000 bases and more — provide a level of contiguity and completeness in genome assemblies that simply isn’t possible with short-read sequencers. They…

Why DNA Size Selection Matters in NGS Pipelines

Of all the sample prep steps necessary for next generation sequencing, DNA size selection may have the greatest impact on quality of results. After all, ineffective sizing can waste sequencing capacity on low molecular weight material such as adapter-dimers or primer-dimers, while imprecise sizing can prevent bioinformaticians from producing accurate assemblies. High-quality size selection can…
