Peripheral blood is a highly accessible biofluid providing a rich source of information about human physiology and health status. However, for studies of the blood transcriptome with RNA sequencing (RNA-Seq) techniques, high levels of hemoglobin mRNAs...

Global transcriptomic analysis via RNA-seq is often hampered by the high abundance of ribosomal (r)RNA in bacterial cells. To remove rRNA and enrich coding sequences, subtractive hybridization procedures have become the approach of choice prior to RNA-seq, with their efficiency ...
Read More »Success in RNA-Seq – Sample Prep and Workflow considerations
by Natalie McDonald, PhD RNA in the cell is comprised of a variety of populations, including traditional poly-adenylated messenger RNA (polyA RNA), non-adenlyated RNA, which may be coding or regulatory, ribosomal RNA (rRNA) and small and micro RNA. The first ...
Read More »Comparison of RNA-Seq by poly (A) capture, ribosomal RNA depletion, and DNA microarray for expression profiling
RNA sequencing (RNA-Seq) is often used for transcriptome profiling as well as the identification of novel transcripts and alternative splicing events. Typically, RNA-Seq libraries are prepared from total RNA using poly(A) enrichment of the mRNA (mRNA-Seq) to remove ribosomal RNA ...
