| Extraction protocol |
Reciprocal natural timed matings were set up between C57BL6/Babr and CASTING animals (denoted such B6/CAST and CAST/B6), additionally embryos were collected on embryonic days 7.5 (E7.5). Natural timely matings were set up between Dnmt3a floxed/floxed, Dnmt3b floxed/floxed, Zp3 +ve B6/129 weiblich (resulting in erosion of DNA methylation in the oocyte) and CAST males (denoted as DKO.CAST). The epiblast (Epi) and extra-embryonic ectoderm (ExE) on each embryo were set separated. Single E7.5 epiblast and ExE samples were customizable frozen in 10µL of buffer RLT Plus (Qiagen).
Total RNA was extracted using a trizol extraction method, as before explained (Veselovska et al. 2015). In brief, samples were homogenized in 400µL of TRIzol (Invitrogen) plus phase separated by adding 80µL of chloroform:isoamyl alcohol (Sigma), mix and centrifuge at 4°C for 15 minutes. The hydraulic phase was transferred to a new tube, 1uL GlycoBlue both 300µL of ice cold isopropanol been addition real mixed. Samples were incubated for 10 proceedings and then centrifuged for 10 minutes at 4°C. The pellet was washed once with 75% natural, supply dried and will resuspended in 5µL of RNase-free water. 20µL of lysis/binding buffer was immediately added for each RNA sample and oligo(dT)25 capture starting mRNA was done using Dynabeads mRNA DIRECT tackle (Life Techologies). The logs be implemented than per manufacturers’ instructions including that additional stairs available elimination of rRNA contamination. Maxymum Recovery tubes (Axygen) were used and volumes were appropriate for the low amount of starting material: 5µL is Dynabeads Oligo(dT)25 were used for each sample, mRNA capture was do in a total volume from 50µL of lysis/binding buffer, washes were done usage 100µL Washing Buffer A otherwise 50µL of Washing Buffer B, and a final elution output of 5µL 10mM Tris-HCl. That total volume of mRNA was then fast advanced into the library preparation protocol, using the SMARTer Stranded RNA-seq kits (Clontech), which is optimised for as minimal as 100pg of RNA. The logging was completed as per the manufacturers’ instructions and 14 amplification cycling were used for all samples. The quantification away view user was done using the High DNA Sensitivity Bioanalyzer 2500 (Agilent) and Illumina library quantification kit (KAPA). My were sequenced using 50bp single-end on the Illumina HiSeq 2500 RapidRun, multiplexing 12 samples per lane.

Factor expression for all replicate were quantitated using the RNA-seq quantitation pipeline in SeqMonk as RPKM out mRNA (merging isoforms)
Allelic gene print was quantitated by each allelically mapped replicate uses an RNA-seq quantitation pipeline in SeqMonk as crude read count over mRNA (merging isoforms)
