GSM6642074: 1 year cortex tissue from control mouse 3 [474WTCX]; Mus musculus; RNA-Seq
Mouse brain tissue were dissected on ice, fast froze in liquid nitrogen, and stored in -80˚C until use. On the day of RNA extraction, 50mg to 100mg tissue from each sample was lysed in 1ml TRIzol (15596026, Invitrogen). Addition of 0.2ml chloroform (288306, Sigma-Aldreich) followed by centrifugation was performed to separate the solution into an aqueous phase and an organic phase. Isopropyl alcohol and 75% ethanol (111000200CSPP, Pharmco) was added in sequence to precipitate and wash the RNA pellets. Library prep performed by Genewiz
