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 […]
EpiGenie Guide: ChIP Antibody ValidationFebruary 11, 2013If you can find a ChIP Grade or ChIP Validated antibody, then you’ve got a head start. But there’s no reason to stress if you can’t. Leave that for the data analysis part of your experiments (only kidding). A quick check of the spec sheet of any antibody can reveal lots of useful info. Here […]
EpiGenie 5hmC Technology GuideOctober 31, 2012A couple of years ago, researchers keen to analyze 5-hmC had a couple of options, but those early approaches couldn’t quite satisfy all of their increasing demands. Fast-forward a bit and it’s a very different story. Today there’s a plethora of options, each with its own strengths and weaknesses. As a result, one of the […]
Guide: Key Restriction Enzymes for DNA Methylation AnalysisOctober 22, 2012Enzymes and, in particular, restriction enzymes have been invaluable assistants in the laboratory for decades, so it is not surprising that they have been instrumental in driving discoveries in epigenetics-related research as well. Enzymatic manipulation of methylated DNA has seen a tremendous amount of innovation over the last 30 years, making these DNA modifying enzymes great […]
Free White Paper: Histone Acetylation and Methylation – Epigenetic Modulators of Gene ExpressionSeptember 26, 2012Histone acetylation and methylation are important cellular processes, but it can be hard keeping track of the structural ups and downs from HATs and HDACs. This free white-paper provides an informative, concise review of the key players in histone acetylation and methylation and their impact on specific residues. Download here >>>
