Instrument: Illumina Genome Analyzer II
Strategy: ncRNA-Seq
Source: TRANSCRIPTOMIC
Selection: size fractionation
Layout: SINGLE
Construction protocol: Zebrafish embryos were collected at the 256-cell stage, sphere stage, shield stage, and 1dpf. Total RNA was isolated from embryos using Trizol. RNAs were fractionated on 15% denaturing polyacrylamide gels and small RNAs between 15-30 nucleotides were excised and purified. cDNA libraries were generated using specific linkers and RT/PCR, as previously described. Libraries were sequenced in the Genome Technology Core of Vanderbilt University using the Illumina sequencing platform.
