Overview
ATAC sequencing (Assay for Transposase-Accessible Chromatin using sequencing) is a cutting-edge technique that maps chromatin accessibility across the genome. By leveraging a hyperactive transposase (Tn5) that simultaneously fragments and tags accessible chromatin regions with sequencing adapters, ATAC-seq enables the identification of open chromatin, which is a hallmark of active regulatory elements such as promoters, enhancers, insulators, and transcription factor binding sites. This method requires minimal input material compared to traditional approaches like DNase-seq or MNase-seq, making it highly efficient and sensitive. At DNA Labs India, we offer comprehensive ATAC sequencing and analysis services at an affordable cost of INR 60,000. Our service includes library preparation, high-throughput sequencing, and advanced bioinformatics analysis to identify differentially accessible regions, transcription factor footprints, and nucleosome positioning. This test is invaluable for researchers and clinicians studying gene expression regulation, epigenetic modifications, and disease mechanisms. It is particularly useful in oncology, immunology, neurology, and cardiovascular research, where understanding chromatin dynamics can reveal novel biomarkers and therapeutic targets. Our state-of-the-art facility ensures high-quality data generation and rigorous quality control. The turnaround time is 10 weeks, and we provide detailed interpretation reports to assist in clinical decision-making. With free home sample collection across major cities in India, DNA Labs India makes advanced genomic testing accessible and convenient.

The primary purpose of ATAC sequencing is to assess chromatin accessibility, which reflects the regulatory landscape of the genome. This test helps identify active regulatory elements, transcription factor binding sites, and nucleosome positioning. It is used to understand gene expression regulation, identify disease-associated epigenetic changes, and discover potential biomarkers. In clinical settings, ATAC-seq can aid in diagnosing genetic disorders, characterizing tumors, and guiding targeted therapies.

Questions customers ask
Frequently asked questions
What is ATAC sequencing?
ATAC sequencing (Assay for Transposase-Accessible Chromatin using sequencing) is a technique that identifies open chromatin regions in the genome, which are indicative of active regulatory elements.
What is the cost of ATAC sequencing in India?
At DNA Labs India, the cost is INR 60,000, which includes library preparation, sequencing, and analysis.
What sample is required for ATAC sequencing?
The test requires extracted DNA, typically obtained from a blood sample or tissue biopsy.
How long does it take to get results?
The turnaround time is approximately 10 weeks from sample receipt.
Is fasting required before the test?
No, fasting is not required for ATAC sequencing.
Can ATAC sequencing diagnose cancer?
ATAC sequencing can identify regulatory changes associated with cancer, but it is not a standalone diagnostic test. It is often used in research or alongside other tests.
Is home sample collection available?
Yes, we offer free home sample collection for online bookings across major cities in India.
What is the difference between ATAC-seq and RNA-seq?
ATAC-seq measures chromatin accessibility, while RNA-seq measures gene expression levels. They provide complementary information.
Are there any risks associated with the test?
The test involves a routine blood draw, which carries minimal risks such as slight bruising or infection.
Who should consider ATAC sequencing?
Individuals with suspected genetic or epigenetic disorders, cancer patients, or researchers studying gene regulation may benefit.
How is the data analyzed?
Bioinformatics pipelines align sequencing reads, identify peaks of accessibility, and annotate them to genomic features.
Is the test covered by insurance?
Insurance coverage is not guaranteed; it depends on the policy. We recommend checking with your provider.
