title: GSM1144687: SpleenMiwi2KO; Mus musculus; RNA-Seq
library_construction_protocol: Liver and spleen were removed, flash frozen in liquid nitrogen, and small RNA (10-200bp) was harvested using RNAzol RT reagent.  RNA were then run on a polyacrylamide gel, and RNA with size from ~24-31 nt was purified and used for the construction of sequencing libraries. RNA libraries were prepared using the Illumina Small RNA v1.5 Sample Preparation kit.
