Gut Microbiota PacBio SMRT Sequencing


Gut Microbiota PacBio SMRT Sequencing

The genes of gut microbes that comprise the microbiota surpass human genes by more than 100-fold, with over 3 million bacterial genes in the gut on its own, the microbiome has been dubbed "another organ" or "our second genome." Anaerobes make up over 99 percent of the bacteria in the gut, and many of them haven't been extensively examined because they can't be cultivated outside of their hosts. Microbiome evaluation that recovers the full-scale genetic data of gut microbiota has provided useful, efficient, and thorough services, which benefit tremendously from techniques such as PacBio SMRT Sequencing. These techniques are shedding light on gut microbiota studies, allowing researchers to gain an overview of human gut microbial complexity across various hosts in the hopes of addressing health problems that people face.

Highly repetitive components in both eukaryotic and prokaryotic genomes make genome assembly complicated and comprehensive studies of repetitive sequences hard. Long-read sequencing generates reads of several or dozens of kilobases (kbs), enabling the resolution of huge structural characteristics by spanning complex or repetitive areas with a single continuous read. It can show where methylated bases happen, giving detailed data about DNA methyltransferases encoded by the genome, in addition to much longer and incredibly reliable DNA sequences from specific unamplified molecules. PacBio SMRT sequencing offers distinct benefits in de novo genomics, metagenomics, transcriptomics, and epigenetics research.

About Our PacBio SMRT Sequencing Service

Creative Proteomics utilize the innovative PacBio SMRT devices (PacBio SR II and PacBio Sequel) are used for a variety of research projects, such as whole de novo genome assembly, full-length target sequencing, metagenomics research, full-length transcript sequencing, and genome-wide DNA modification evaluation. To guarantee confident and high certainty outcomes, our professionally trained expert team performs quality management after each procedure. De novo assembly, base modification identification, single-molecule consensus generation, transcript assessment, amplicon evaluation, and sequence orientation with variant identification are all part of our bioinformatics pipeline. More data mining options are accessible based on your requirements.

Our Advantages

  • High Accuracy: Sequencing without systematic error accomplishes a consensus accuracy of >99.999 percent. Examine the advantages of highly precise long-read sequencing.
  • Uniform Coverage: Because there is no bias based on GC material, you can sequence through areas that other techniques can't reach.
  • Single-Molecule Resolution: Collecting sequence data from native DNA or RNA molecules allows for highly precise long reads with single-molecule precision of >99.9%.
  • Base alterations are instantly identified during sequencing because there is no PCR amplification step.
