What is NGS and How Does Illumina Sequencing Work?
Next-generation sequencing (NGS) is a technology that allows us to determine the order of nucleotides in entire genomes or targeted regions of DNA or RNA. One of the most widely used NGS technologies is Illumina sequencing, which employs a method called sequencing by synthesis (SBS). This method tracks the addition of labeled nucleotides as the DNA chain is copied, generating DNA sequencing data in a massively parallel fashion.
Compared to older methods like the Sanger chain-termination method, Illumina sequencing offers several advantages. It provides high-accuracy data with increased sensitivity, enabling us to detect even rare genetic variants. Illumina sequencing is also highly scalable, allowing labs to generate large amounts of data in a single run using different instrument models.
With Illumina sequencing, researchers can obtain DNA sequencing data output ranging from hundreds of kilobases to multiple terabases, depending on the instrument used. This vast amount of data allows for in-depth analysis and a better understanding of complex biological systems. Illumina sequencing has revolutionized genomics research, enabling us to study whole genomes, target specific genomic regions, perform RNA sequencing for gene expression analysis, explore epigenetic factors, study cancer samples, investigate the human microbiome, and identify novel pathogens.

Deep Sequencing and Its Uses
Deep sequencing, also known as high-depth or ultra-deep sequencing, is a powerful technique used in genomics research to analyze genomic regions at a granular level. By sequencing a genomic region multiple times, deep sequencing allows researchers to detect rare clonal types or cells that may comprise only a small proportion of the original sample. This approach has significant applications in various research areas, particularly in cancer research and the study of rare cell populations.
In cancer research, deep sequencing plays a crucial role in identifying mutations within tumors. Tumors often contain a mixture of normal and tumor tissue, as well as multiple sub-clones of cancer cells. Deep sequencing enables researchers to accurately characterize the genetic landscape of tumors, providing insights into tumor evolution and treatment resistance. By detecting rare clonal types, deep sequencing helps researchers understand the heterogeneity of tumors and design personalized treatment strategies.
Deep sequencing is not limited to cancer research. It is also valuable in studying rare cell populations in other research fields, such as immunology and microbiology. By analyzing genomic regions of interest with exceptional depth, researchers can uncover rare genetic variants and gain insights into the functional significance of these variants. Additionally, deep sequencing allows for the detection of low-frequency mutations or genetic alterations that may be relevant to disease progression or treatment response.
Table: Applications of Deep Sequencing

In conclusion, deep sequencing provides researchers with a powerful tool to explore genomic regions in detail. Its applications in cancer research and the study of rare cell populations have transformative implications for understanding disease mechanisms and developing targeted therapies. By enabling the detection of rare clonal types and low-frequency mutations, deep sequencing opens new avenues for precision medicine and personalized treatment approaches.
Factors Affecting Sequencing Depth in Cancer Research
In cancer research, achieving the appropriate sequencing depth is crucial for accurate detection and analysis of cancer mutations. Several factors influence the sequencing depth required for a specific study, ensuring reliable results and insights into tumor biology. Let’s explore these factors:
Tumor Purity
Tumor purity refers to the proportion of tumor cells in a sample that contains both normal and tumor tissue. Higher tumor purity necessitates deeper sequencing depth to accurately detect and characterize tumor mutations. This is because lower tumor purity can dilute the mutation signals, making them harder to distinguish from normal DNA. Therefore, it is essential to assess tumor purity before determining the appropriate sequencing depth for a cancer research study.
Tumor Heterogeneity
Tumor heterogeneity refers to the presence of multiple clonal types within a tumor. Different clonal types may have distinct genetic mutations, which can affect treatment response and disease progression. To capture the full spectrum of tumor heterogeneity, deeper sequencing depth is required to ensure the detection of low-frequency mutations and subclones. Understanding tumor heterogeneity can provide valuable insights into cancer evolution and guide personalized treatment strategies.
Sensitivity
The desired sensitivity level of a study also impacts the sequencing depth requirements. Low-frequency clones with clinically important mutations may require higher coverage to ensure their detection. Sensitivity can be influenced by factors such as the size of the target region, the specific mutation of interest, and the clinical significance of the mutation. Researchers must consider these factors when determining the appropriate sequencing depth to achieve the desired sensitivity level.
Summary table:
| Factor | Definition |
|---|---|
| Tumor Purity | The proportion of tumor cells in a sample |
| Tumor Heterogeneity | The presence of multiple clonal types within a tumor |
| Sensitivity | The desired level of mutation detection |
By considering tumor purity, tumor heterogeneity, and sensitivity, researchers can determine the appropriate sequencing depth for their cancer research studies. Adequate sequencing depth ensures reliable detection and characterization of cancer mutations, providing valuable insights into tumor biology and personalized treatment strategies.
