Targeted RNA sequencing library preparation: QuantSeq-Flex

The QuantSeq-Flex Kit from Lexogen enables the generation of Illumina®-compatible targeted RNA sequencing libraries from any RNA sample. Utilising custom primers for first or second strand synthesis, the QuantSeq-Flex kit features a simple workflow to generate ready-to-sequence libraries in just 4.5 hours. This kit includes additional modules for Reverse Transcription (RT) and Second Strand Synthesis (SSS) using custom primers and offers maximum flexibility of targets and input material.

Benefits of using the QuantSeq-Flex kit
 Direct counting for gene expression quantification: produces one fragment per transcript
• Sequence-ready libraries in just 4.5 hours, with <2 hours hands-on time
• Targeted RNA-Seq from any RNA sample
• Suitable for targeted sequencing of gene panels, enrichment detection of fusion genes, and various other types of transcripts
• Intended for a high degree of multiplexing
• Libraries are compatible with Illumina® sequencers
• No prior poly(A) enrichment or rRNA depletion required

QuantSeq-Flex targeted RNA-Seq library preparation workflow

QuantSeq-Flex workflow

Read 1 reflects the RNA sequence. The reverse transcription reaction can either be primed using an oligodT primer (included in the kit) or a target-specific primer (not included, custom designed for desired targets). Second strand synthesis can either be initiated by random priming (included in the kit) or by using a target-specific primer (not included, custom designed for desired targets). Depending on the combination of different priming options 4 different libraries can be generated.
