title: GSM8646294: Placental tissue, Percreta, Percreta1; Homo sapiens; RNA-Seq
library_construction_protocol: A total amount of 1 µg RNA per sample was used as input material for the RNA sample preparations. RNA degradation and contamination was monitored on 1% agarose gels. RNA purity was checked using the NanoPhotometer® spectrophotometer (IMPLEN,  CA,  USA) .RNA integrity was assessed using the RNA Nano 6000 Assay Kit of the Bioanalyzer 2100 system (Agilent Technologies,  CA,  USA). Sequencing libraries were generated using NEBNext® UltraTM RNA Library Prep Kit for Illumina® (NEB,  USA) following manufacturer's recommendations and index codes were added to attribute sequences to each sample.
