mRNA capture enriches protein-coding transcripts, enhances gene expression analysis, and quantifies mRNA levels. It reduces RNA population complexity, improving sensitivity and specificity. However, it may exclude non-coding RNA species for certain experiments.
Ribosomal RNA (rRNA) depletion is a comprehensive method for studying a wide range of RNA species, including mRNAs and non-coding RNAs. It offers advantages like capturing the entire transcriptome but may dilute sequencing depth for other RNA species.
