Summary
Pacific Biosciences' SMRT sequencing was used to extend the HLA-A*02:13 sequence. This advancement provides a more complete genetic reference for this important human leukocyte antigen allele.
Area of Science:
- Genomics
- Immunogenetics
Background:
- Human Leukocyte Antigen (HLA) genes are critical for immune response.
- Accurate sequencing of HLA alleles is essential for transplantation and disease association studies.
Purpose of the Study:
- To extend and refine the sequence of the HLA-A*02:13 allele using advanced sequencing technology.
Main Methods:
- Utilized Pacific Biosciences' Single Molecule, Real-Time (SMRT) sequencing technology.
- Applied long-read sequencing to achieve comprehensive coverage of the HLA-A*02:13 locus.
Main Results:
- Successfully extended the sequence of HLA-A*02:13.
- Generated high-quality, contiguous sequence data for the allele.
Conclusions:
- The extended sequence provides a more accurate and complete reference for HLA-A*02:13.
- This improved reference benefits research in immunogenetics, personalized medicine, and disease association studies.

Next-generation Sequencing
97.9K
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.

Cis-regulatory Sequences
11.6K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Sanger Sequencing
773.5K
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...

Maxam-Gilbert Sequencing
12.7K
In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.
