GSM9001394: 4T1_DMSO_01; Mus musculus; RNA-Seq
Total RNA was extracted from the samples by Trizol reagent (Invitrogen) separately. The RNA quality was checked by Agilent 2200 and kept at −80°C. The RNA with RIN (RNA integrity number) > 7.0 is acceptable for cDNA library construction. The cDNA libraries were constructed for each RNA sample using the TruSeq Stranded mRNA Library Prep Kit (Illumina, Inc.) according to the manufacturer's instructions. Generally, the protocol consists of the following steps: Poly-A containing mRNA was purified from 1ug total RNA using oligo(dT) magnetic beads and fragmented into 200-600 bp using divalent cations at 85℃ for 6 min. The cleaved RNA fragments were used for first- and second-strand complementary DNA (cDNA) synthesis . dUTP mix was used for second-strand cDNA synthesis, which allows for the removal of the second strand.
