Use of High-Density Histone Peptide Arrays for Parsing the Specificity of a Histone-Modifying Enzyme Complex
12 May 2013Methylation of arginine residues by protein arginine methyltransferases (PRMTs) is an underexplored component of the histone code by epigenetic regulation. The histone code encompasses an exceedingly complex combination of post-translational modifications (PTMs) of histone residues that marks and directs regulation of the underlying genome. This application note describes the use of a novel peptide array to study the substrate specificity of a critical enzyme complex.

Genome AnalysisGenomics, the study of genomes, includes functional genomics, evolutionary genomics and comparative genomics. There are many genomic technologies such as DNA sequencing of whole genomes, computational biology and bioinformatics. DNA and nucleic acids must be isolated and concentrated from cells for analysis with kits, automated analyzers and software. Other useful technologies for studying genomics include PCR, microarrays and electrophoresis.ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.Microarray AnalysisMicroarrays, also known as biochips, are used for the detection and analysis of multiple genes, proteins, antibodies, or biomarkers on a single microchip. This can reveal information on protein or gene expression, single nucleotide polymorphism (SNP), copy number variation (CNV), epigenetics and patient health in clinical diagnostic tests. Discover a range of microarray scanners and prefabricated antibody, protein, RNA and DNA microarrays for your analysis or consider creating your own custom microarrays with a microarray printer.

The main methods of protein crystallization include sitting drop, hanging drop and microbatch. It is important to control parameters such as pH, temperature and concentration. Following crystallization, detectors and software are used for data collection and analysis.Epigenetic AnalysisEpigenetic analysis products are used to study heritable phenotype changes that do not alter the DNA sequence, such as DNA modifications affecting gene activity. Determine whether genes have been methylated with DNA methylation quantification kits or methylation microarrays. Assess epigenetic regulation with histone modification kits or ChIP-on-chip microarrays. Kits are also available for bisulfite conversion and amplification of your samples, as well as epigenomic library preparation kits for next-generation sequencing (NGS).
