For a long time, amplicon sequencing has been a vital technique among microbiome researchers. It has been used to help scientists generate whole community bacteria or fungi in any complex sample. This transformative technology enables precise and efficient analysis of unique genomics regions by amplifying targeted regions through polymerase chain reaction (PCR). Unlike whole-genome sequencing, the approach minimizes costs and complexities, making it a preferred solution for many applications, from microbial studies to environmental research to mutation discovery.
Understanding Amplicon Sequencing and Its Uses
Amplicon sequencing involves analyzing targeted genetic. In simple words, it is the selection and separation of genetic regions of interest before sequencing to determine genetic disparity between samples of a targeted region.
It is used in a wide range of applications for microbe investigations. It is applied in oncology to profile tumors and detect mutations. It helps researchers identify genetic mutations connected to cancer development and progression.
It is used in public health to track pathogen. It helps researchers track infectious disease outbreaks by monitoring pathogens and studying viral and bacterial mutations. It helps them to respond to disease outbreaks more effectively.
It has also been helpful in identifying individuals carrying genetic mutations that can be passed to the next generation. It enables the detection of known pathogenic variants related to inherited disorders, allowing diagnosis and possible treatment.
Benefits of Amplicon Sequencing
Simplicity
Amplicon sequencing allows the study of specific gene regions unlike whole genome sequencing. A specific gene region can be targeted to identify different organisms of interest. It analyzes predefined regions of genome with exceptional precision. This approach helps scientists to focus on specific areas or genes of interest and avoid unnecessary assessments.
Time and Cost Efficient
Unlike other broader methods of sequencing, it is cost and time-efficient since it allows researchers to avoid sequencing entire genomes, thus reducing computational and financial resources required. Researchers don't have to waste a lot of time sequencing unnecessary genomes, lowering data storage and analysis due to smaller datasets. They also spend less time on library preparations and sequencing.
High Multiplexing Capability
It has the ability to process hundreds of Amplicons in a single reaction, thus offering unparalleled scalability. The possibility to multiplex helps researchers to asses a wide range of targets simultaneously, making it the best approach for large scale studies. It increases efficiency in researches that require broad genetic variant screening because it supports large sample sizes in a single run.
High Sensitivity
Amplicon sequencing increased sensitivity to organisms within the samples. Its ability to amplify PCR of the gene regions of interest allows it to discard all noise of the non-targeted genes. This increases the signal of microbial targets within the sample.
Ability to Sequence Challenging Regions
This approach of sequencing excels in assessment of genomic regions that are difficult to sequence. For instance, regions with high GC content are challenging to sequence using other methods. However, PCR-based amplification step in amplicon sequencing offers reliable results regardless of the problems.
In conclusion, amplicon sequencing is a methodology that has greatly impacted research in genomes. Its ability to analyze targeted regions makes it the best option for different applications, including infectious disease study and cancer research. It is cost and time effective and offers simplicity. Researchers don't have to waste time sequencing the whole genomes thus spending less lab-time and saving resources.
