Delving into the intricate world of microorganisms, 16S/18S/ITS amplification sequencing emerges as a powerful tool for scientists and researchers. This technique, championed by CapitalBio, offers a window into the diverse communities of bacteria, archaea, and fungi present in various environments, from the human gut to soil samples. By understanding the principles and workflow of this sequencing approach, we unlock its potential to revolutionize fields like medicine, agriculture, and environmental science.
16S/18S/ITS Amplification Sequencing Core Principles: Diving into the Molecular Machinery
16S 18S ITS amplification sequencing hinges on the unique properties of ribosomal RNA (rRNA) genes. These genes, present in all living organisms, exhibit highly conserved regions interspersed with hypervariable segments. The conserved regions serve as perfect targets for "universal primers," short DNA sequences designed to bind to a wide range of organisms within a specific domain (bacteria/archaea or eukaryotes).
16S rRNA: This gene is primarily used for bacterial and archaeal identification and classification. Its hypervariable regions offer sufficient variability to differentiate even closely related species.
18S rRNA: This gene serves as a marker for eukaryotic diversity, particularly fungi. Similar to 16S rRNA, its hypervariable regions allow for species-level resolution.
ITS (Internal Transcribed Spacer): This non-coding region exists between the 18S and 5.8S rRNA genes in fungi. Its high variability provides even finer taxonomic resolution compared to 18S rRNA alone.
16S/18S/ITS Amplification Sequencing Workflow: A Step-by-Step Journey
CapitalBio's 16S/18S/ITS amplification sequencing follows a meticulously designed workflow:
1. Sample Collection and DNA Extraction: The journey begins with collecting the sample of interest, be it soil, water, or a human tissue biopsy. CapitalBio's experts employ specialized techniques to extract high-quality DNA from the sample, ensuring a representative snapshot of the microbial community.
2. PCR Amplification: Using the chosen universal primers, CapitalBio performs a polymerase chain reaction (PCR) to amplify the target 16S/18S/ITS regions. This step exponentially increases the number of copies of these regions, making them suitable for subsequent sequencing.
3. Library Preparation: The amplified DNA fragments undergo library preparation, where they are fragmented, adapter sequences are added, and size selection is performed. These steps ensure compatibility with the chosen sequencing platform.
4. High-Throughput Sequencing: CapitalBio utilizes advanced sequencing technologies like Illumina or Ion Torrent to generate millions of short reads from the prepared library. These reads represent individual DNA fragments from the amplified regions.
5. Data Analysis and Interpretation: The generated sequencing data undergoes bioinformatic analysis, where experts use specialized software to identify and classify the microorganisms present in the sample based on their 16S/18S/ITS sequences. CapitalBio's team provides comprehensive reports and visualizations that translate complex data into meaningful insights.
