ATAC-seq (Assay for Transposase Accessible Chromatin using sequencing) is a high-throughput sequencing technology that uses the transposase Tn5 to investigate chromatin accessibility. The core principle of ATAC-seq is to use the transposase Tn5 to cleave open chromatin regions and, in doing so, to incorporate sequencing adapters into the DNA at these regions. These adapter-tagged DNA fragments are then subjected to high-throughput sequencing to identify open chromatin regions in the cell nucleus. These regions are typically sites in the genome that are readily accessible to transcription factors and other regulatory proteins. Therefore, ATAC-seq is a powerful tool for studying epigenetic changes in gene expression regulation, cell differentiation, and disease

Our Comprehensive Service
At LC Sciences, we offer a genome-wide microRNA expression profiling service utilizing a microarray detection system that was developed specifically for microRNA detection. Send us your total RNA sample and we’ll perform all the necessary functions from sample QC through data analysis. We can perform microarray analysis on a single sample to create a simple expression profile or we can hybridize two samples to the same microarray for “dual sample” analysis. This is very useful whenever comparison of two samples is needed such as wildtype vs. mutant or samples treated in two different ways.
Our “Total RNA to Data” comprehensive service includes: Sample QC, Sample Preparation and Labeling, microRNA Detection (hybridization to a µParaflo® microfluidics chip), Array Scan and Data Extraction, and Full Data Analysis.
In about 2-3 weeks you will receive: original and processed scan images, array layout and a list of sequences, raw and processed data, a list of differentially expressed transcripts (dual sample arrays only), and a summary of the results.
