title: GSM3208997: NT KDM45 DNMT3AB 2-cell 1 (RNA-Seq); Mus musculus; RNA-Seq
library_construction_protocol: Harvested cells were washed three times in 0.5% BSA-PBS solution and transferred into the lysis buffer. cDNA were synthesized using primers with 24-nt poly(dT),then a universal tail was added to the second strand cDNAs. After 18-20 cyclesof PCR, the PCR product is purified by QIAquick PCR purification kit(28104). The prepared cDNA are sheared using Covaris S220. Fragment ends are repaired using NEBNext End Repair Module(E6050), then a NEBNext dA-Tailing Module(E6053) was used to yield a protruding 3- 'A' base for ligation of Illumina's adapters.After adapter ligation DNA was PCR amplified with Illumina primers for 8-12 cycles. library fragments of 200-500bp were band isolated from an agarose gel.
