Name: GSM6034567
Instrument: Illumina NovaSeq 6000
Strategy: miRNA-Seq
Source: TRANSCRIPTOMIC
Selection: size fractionation
Layout: SINGLE
Construction protocol: Total RNA from oocytes of different species were extracted with TRIzol Reagent (Ambion, USA), respectively. Small RNA library construction. Briefly, the single oocytes were incubated at 72 °C for 3 min then cooled in ice. After 3′ adapter ligation, the samples were incubated with 5 U of lambda exonuclease and 25 U of 5′ de-adenylates. Small RNAs were reverse-transcribed after 5′ adapter ligation. Two rounds of amplification were conducted to get the libraries and the libraries were recovered with 6% polyacrylamide gel. mRNA library construction. In brief, single oocytes were incubated at 72 °C for 3 min and then cooled on ice. For every single oocyte, 1 μl of a 1/500,000-1/50,000 dilution of the ERCC RNA Spike-In Mix (Invitrogen, 4456740) was added. After reverse transcription and PCR pre-amplification, cDNAs were purified and 3 ng of purified cDNA was used for a tagmentation reaction with Tn5 transposase.
