eBook: ChIP Seq Data Analysis Tools & DatabasesSeptember 13, 2016Chromatin immunoprecipitation (ChIP) is a powerful workflow for analysis of chromatin structure. The antibody-based pulled down of protein-DNA interactions is only half the process. Once the genomic regions bound by a protein are enriched and sequenced, bioinformatics tools and pipelines are necessary to identify, characterize, and compare these regions between samples. This ‘dry’ side of the ChIP workflow is […]
eBook: ChIP Reloaded | Recent Advances & Technical GuidanceMarch 25, 2016In this eBook, we’ve summarized several recent technical advances in ChIP that simplify the process and improve performance. Then we tossed in invaluable technical guidance from ChIP experts tackling every thing from working with challenging samples to data normalization. To top it all off, we’ve highlighted some new web applications that aim to streamline ChIP data analysis […]
eBook: DNA Demethylation in DevelopmentMarch 19, 2016This ebook provides an introduction to the key cytosine base modifications: 5-methylcytosine, 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC), and 5-carboxylcytosine (5caC) that have been at the center of intense study in recent years. Inside, we’ve compiled numerous highlights that provide background on how these modifications function in DNA demethylation and also highlight the growing data that captures the role of demethylation […]
Guide: Optimizing ChIP Seq for FFPE SamplesFebruary 25, 2016Inside the world’s formalin-fixed, paraffin-embedded (FFPE) tissue repositories exists an enormous store of biological information. This valuable preservation technique allows researchers to perform histological and even genetic analysis years after sample collection. Although the FFPE process is a valuable preservation process, it presents challenges to researchers seeking to apply epigenetic techniques such as chromatin immunoprecipitation […]
Guide: Bisulfite-Converted DNA AmplificationJanuary 12, 2015Over the years, bisulfite conversion has become the most widely used method for DNA methylation analysis. It is the most convenient and effective way to map DNA methylation to individual bases. As the first step in numerous downstream analysis techniques, it is absolutely critical that the bisulfite conversion process is understood and performed well. Our […]
EpiGenie Guide: RNA Immunoprecipitation (RIP) and BeyondJuly 10, 2013RNA binding proteins (RBPs) play important roles in many cellular and disease processes, together with their DNA binding brethren, they compromise almost one quarter of annotated human genes. The tools used to understand when and where these proteins bind and interact with RNAs in the cell have lagged behind those for protein-DNA interactions, although they […]
Application Note: Automated Bisulfite ConversionJune 14, 2013Unlike more mainstream assays, bisulfite conversion approaches have been dependent on manual manipulation of spin plates and columns or have been of limited throughput. By adapting the clean-up of bisulfite converted DNA to a magnetic bead based procedure and coupling it to the Freedom EVO® platform, Zymo Research has opened the door to high-throughput bisulfite […]
Guide: Getting Started with Genome-Wide 5-mC and 5-hmC SequencingApril 10, 2013With recent advances in sample preparation, highthroughput sequencing, and bioinformatics, researchers looking to study DNA methylation and hydroxymethylation now have several options for investigating these epigenetic modifications on a genome-wide scale. The following technologies offer varying levels of resolving power, with some offering regional estimates of DNA methylation status, while others provide quantitative values at […]
Guide: Peak Calling for ChIP-SeqFebruary 27, 2013Chromatin-immunoprecipitation sequencing (ChIP-seq) is the most widely used technique for analyzing Protein:DNA interactions. Very briefly, cells are cross-linked, fragmented and immunoprecipitated with an antibody specific to the target protein; the resulting ChIP DNA fragments are used as the template in a next-generation sequencing library preparation and many millions of short sequence reads are generated for […]
Guide: Getting Started with ChIP-SeqFebruary 27, 2013Chromatin-immunoprecipitation (ChIP) followed by sequencing of the immuno-precipitated DNA is a powerful tool for the investigation of Protein:DNA interactions. To perform ChIP-seq, chromatin is isolated from cells or tissues and fragmented. Antibodies against chromatin associated proteins are used to enrich for specific chromatin fragments. The DNA is recovered, sequenced and aligned to a reference genome […]
