Summary
Next-generation DNA sequencing platforms offer high throughput and lower costs compared to older methods. While read lengths are shorter, new techniques enhance their utility for comprehensive genome analysis.
Area of Science:
- Genomics
- Molecular Biology
- Biotechnology
Background:
- Capillary sequencing is being superseded by new technologies for high-throughput DNA analysis.
- Next-generation sequencing (NGS) platforms utilize flow cell technology for mass parallel sequencing.
Purpose of the Study:
- To compare and contrast emerging DNA sequencing platforms.
- To evaluate their performance, cost, and application suitability.
Main Methods:
- Comparative analysis of various NGS platforms.
- Assessment of sequencing chemistry, throughput, cost, and error models.
- Evaluation of data handling and template formats.
Main Results:
- NGS platforms exceed capillary sequencing in daily base output and cost-effectiveness.
- Shorter read lengths and limited simultaneous sample capacity present practical challenges.
- Paired-end sequencing and template selection methods improve genome analysis utility.
Conclusions:
- NGS technologies represent a significant advancement in DNA sequencing capabilities.
- Continuous improvements are expected, with potential for future disruptive technologies.

03:00Next-generation Sequencing
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features.

01:23Flow Cytometry
The development of flow cytometry techniques began in 1934 with initial attempts by Andrew Moldavan, a bacteriologist who counted the cells in a flowing capillary system. Moldavan pumped cells through a capillary tube focused under a microscope for visualization. The invention of photometry allowed the measurement of differentially-stained cells, and Louis Kamentsky developed the first multiparameter flow cytometer in 1965 to identify and count the cancer cells in cervical tissue specimens.

03:21RNA-seq
RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
