RNA-seq03:21

RNA-seq

12.7K
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. 
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

Next-generation Sequencing

101.9K
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....

Sanger Sequencing

780.2K
DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

Single Nucleotide Polymorphisms-SNPs

20.1K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

    Area of Science:

    • Genomics
    • Molecular Biology
    • Biotechnology

    Background:

    • Single-cell genome sequencing faces challenges with low physical coverage and high error rates.
    • Distinguishing true biological variants from technical artifacts is difficult in single-cell data.

    Purpose of the Study:

    • To develop and validate a robust method for high-coverage, accurate single-cell genome sequencing.
    • To improve the detection efficiency of genetic variants in individual human cells.

    Main Methods:

    • The SNES method integrates flow-sorting of single nuclei (G1/0 or G2/M).
    • It employs time-limited multiple displacement amplification (MDA) and exome capture.
    • Next-generation sequencing is utilized to generate high-coverage data.

    Main Results:

    • SNES achieved 96% data coverage from single human cells.
    • The method demonstrated low allelic dropout and false-positive error rates.
    • High detection efficiencies were observed for single nucleotide variants (92%) and indels (85%).

    Conclusions:

    • SNES significantly enhances the accuracy and reliability of single-cell genome sequencing.
    • This method provides a powerful tool for analyzing genetic variations at the single-cell level.
    • It overcomes key limitations of existing single-cell sequencing approaches.
