Source name Haunt CAG KI mES cells
Organism Mus musculus
Characteristics sample type: Haunt CAG promoter knockin in 46C cells (RA, day2)
treatment: LIF withdrawal, 2uM RA, day2
strain: 129/Ola
chirp probes: none
genotype: Haunt CAG KI
cell line: 46C

Growth protocol ESCs were cultured in N2B27 complete "2i" medium including: 100 ml DMEM/F12 basal medium (Life Technologies), 100 ml Neurobasal medium (Life Technologies), 1 ml N2 supplement (Life Technologies), 2 ml B27 supplement (Life Technologies), 1 ml 100 × Glutamax (Life Technologies) and 0.1 mM 2-mercaptoethanol, 1000U/ml recombinant leukemia inhibitory factor (LIF, millipore) and "2i" (1 uM PD03259010, 3 uM CHIR99021) for one day. The cells were then passaged with N2B27 medium without LIF and "2i", and supplemented with 2 uM retinoic acid (RA), change medium everyday. Cells were harvested at day 2 of RA-induced differentiation
Wild-type ESCs or Haunt KO ESCs were maintained in strandard ES medium supplemented with 15% heat-inactivated FCS, 1% of nucleoside mix (100 × stock, Millipore), Penicillin-Streptomycin Solution (100 × stock, Life Technologies), 2 mM Glutamax (100 × Life Technology), 0.1 mM non-essential amino acid, 0.1 mM 2-mercaptoethanol and supplied with 1000 U/ml recombinant leukemia inhibitory factor (LIF, millipore).
Extracted molecule total RNA
Extraction protocol Cells were harvested at day 2 of RA-induced differentiation. TRIzol reagent was added directly into the plate after cold 1 × PBS wash once. The total RNA was extracted according to manufacturer's instructions. mRNA was further isolated by Dynabeads mRNA purification kit (Life Technologies) according to manufacturer's instructions.
The library was constructed by library preparation modules (New England Biolabs) according to manufacturer's instructions. Briefly, mRNA was fragmentated by NEBNext Magnesium RNA Fragmentation Module at 94 ℃ for 5 min. The fragementated RNA was reverse transcribed by SuperScript III First-Strand Synthesis System for RT-PCR kit (Life Technology), 2'nd strand was then synthesized by NEBNext mRNA Second Strand Synthesis Module , the end repair, dA-tailing and adaptor ligation were also following the instruments by respect module. the adaptor for the libary was sythersized from IDT. After liagation, the DNA was amplified by primer 1.0 (AATGATACGGCGACCACCGAGATCTACAC, synthersized from IDT) and 2.0 (CAAGCAGAAGACGGCATACGAGAT, synthersized from IDT) for 12 cycles. After this, the product was further purified and size selected by Ampure XP beads (Beckman Coulter). The library was sequenced on the Genome Analyzer following the manufacturer's protocols.
Total RNA of RNA-Seq were extracted by TRIzol reagent according to manufacturer's instruction. mRNA were further isolated by Dynabeads mRNA purification kit (Life Technologies) according to manufacturer's instruction.
Libraries were prepared by illumina TruSeq Stranded mRNA LT Sample Prep Kit (RS-122-2101) according to the standard protocols of the manufacturer. ChIRP retrieved DNA-seq were prepared by library preparation modules (New England Biolabs) according to manufacturer's instructions.
