A key obstacle in DNA sequencing is the long time required for sample preparation, especially when compared with how fast next-generation sequencers are able to sequence DNA. Now, researchers at the OSChave reduced that time using a new automated sample preparation system. Using the new system, sample preparation of 96 CAGE cDNA libraries, which would normally take a manual operator 42 days, is done in only 8 days.
The researchers further demonstrated, through a comparison of results from the analysis of transcriptional starting sites and their expression levels using CAGE on the single molecule sequencer, that results using the new preparation system are reproducible and comparable to results using manual preparation. The new automated cDNA preparation system can also be applied to a variety of other methods and sequencers.
