Metatranscriptome Sequencing

Community-wide transcriptome profiling to characterize microbial gene expression, functional activity, and responses across complex environments.

Metatranscriptomics utilizes environmental samples to analyze the complete set of transcripts at a given time, uncovering highly expressed genes within microbial ecosystems. Through next-generation sequencing (NGS)-based random RNA sequencing, it generates comprehensive expression profiles, captures temporal gene expression dynamics, and provides deeper insights into the structure, function, and adaptation of complex microbial communities.


Novogene employs advanced Illumina NovaSeq platforms for cDNA library preparation and sequencing, utilizing a paired-end 150-base-pair (150 bp) protocol to consistently deliver high-quality, high-fidelity short-read data. With extensive industry expertise and significant sequencing capacity, Novogene provides a comprehensive range of services designed to meet diverse research requirements seamlessly.
