Stranded mRNA Seq

Preparation of RNA samples for sequencing on the Illumina HiSeq. Described here is a library preparation service only. Once the library is prepared, you will also need to request (and pay for) the sequencing of that library.

Total RNA is input into the workflow where mRNA is isolated using oligo d(T), cDNA is made with reverse transcriptase. Second strand synthesis incorporates uracils in place of thymines. The cDNA is end repaired A tailed and Illumina adapters are ligated. The resultant library is then PCR amplified to have enough material for the sequencer. The enzyme in the PCR reaction does not recognize the uracils and therefore does not amplify the 2nd strand.

Typical Output

~30 ul of 10nM prepared library with a 120 bp insert, you will also get TapeStation reports of the quality of your input RNA and the resultant library.

How to Request

Sample Submission: login through then choose ‘Illumina Sequencing’

Please deliver RNA to NCRC. Courier service from other sites will not guarantee proper temp is maintained!

Sample Requirements

100ng -4ug of good quality, RINs of 8 or higher, DNase treated total RNA in 25-50ul

Typical Turnaround

2-3 weeks

Critical Information

RNA must be delivered on dry ice to NCRC and cannot be left at our pick up sites on campus.
