Comprehensive Gene Expression and Transcriptome Analysis Solutions
Transcriptome analysis experiments enable researchers to characterize transcriptional activity (coding and non-coding), focus on a subset of relevant target genes and transcripts, or profile thousands of genes at once to create a global picture of cell function. Gene expression analysis studies can provide a snapshot of actively expressed genes and transcripts under various conditions.
Next-generation sequencing (NGS) capabilities have shifted the scope of transcriptomics from the interrogation of a few genes at a time to the profiling of genome-wide gene expression levels in a single experiment. Find out how NGS-based RNA sequencing (RNA-Seq) compares to other common gene expression and transcript profiling methods, gene expression microarrays and qRT-PCR. Learn how to analyze gene expression and identify novel transcripts using RNA-Seq.

Download eBookCommon Gene Expression Analysis Methods
A variety of methods may be used to profile gene expression for select targets of interest and/or analyze the coding transcriptome, based on your study goals. Learn about the pros and cons of several key gene expression and transcriptome analysis methods.
Gene Expression Microarrays
Pros: Familiar workflow, high sample throughput for analysis of known genes and transcripts
Cons: Inability to detect novel transcripts; gene expression measurement is limited by background at the low end and signal saturation at the high end1
Learn About Arrays vs. RNA-SeqqRT-PCR
Pros: Familiar workflow, effective for low target numbers
Cons: Can only detect known sequences, low scalability
Learn About qRT-PCR vs. RNA-SeqRNA-Seq
Pros: Broad dynamic range, can be applied to any species, and can detect both known and novel features in a single assay1
Cons: May be less cost-effective when interrogating a limited number of samples for a small set of known transcript variants
