LoopSeq Transcriptome kit

LoopSeq™ Transcriptome library preparation kits enable the generation of long read data from short read Illumina® sequencers with no extra hardware required. Using a set of enzymes to propagate a barcode intramolecularly through any piece of DNA or RNA, the LoopSeq kits use a simple, single tube workflow to eliminate PCR and GC bias as molecules are labelled in the first step and only sequenced/reported once. With significantly reduced error rates compared to those of PacBio® and Oxford Nanopore®, LoopSeq Transcriptome kits accurately determine not only transcript abundance but also unique isoforms.

Benefits of using these LoopSeq kits
• Simple, single tube workflow 
• Highly accurate long-read sequencing
• Unique molecular identifier (UMI)-based transcript counting – barcode based quantification with no PCR bias

LoopSeq technology

LoopSeq technology

LoopSeq technology uses single-molecule counting, which makes it possible to calculate true transcript abundance using barcode based quantification with no PCR bias.

Comparison of Loop Genomics technology vs. Illumina® technology using an ERCC control sample

TruSeq® (left) and LoopSeq Transcriptome kit (right) comparison. TruSeq® provides short reads and quantification via coverage whereas LoopSeq provides synthetic long reads from short reads with single-molecule quantification. Data shows that the LoopSeq Transcriptome kit provides a much more accurate quantification of the synthetic ERCC synthetic control sample.
