ted-RNA(™) 5′ WTA Library Preparation Kit


mRNA and ncRNA data without rRNA removal
Single tube reaction to convert total RNA or mRNA to Illumina® compatible RNA-seq libraries. < 10% rRNA without rRNA subtraction. 1 to 200 ng total RNA input. For gene expression, RNA isoforms, allele specific expression and other applications for nc-, lnc- and mRNA.
User needs to provide PCR reagents and Illumina® indexing reagents.

The ted-RNA 5′ WTA Library Preparation Kit generates sequencing libraries for Illumina® platforms. The novel “ted” technology used in these kits generate full length transcript coverage from purified total RNA. The method does not require RNA fragmentation before library construction and can generate sequencing libraries with larger insert sizes to produce more accurate RNA isoform data. This kit does not require ribosomal RNA removal as rRNA is converted into library molecules at substantially low efficiency.


*filter duplicated reads to remove rRNA is recommended.
