| Sample type |
RNA |
| |
|
| Channel 1 |
| Source name |
Total RNA from murine ES-D3 triple-transfected embryonic stem cells labeled with Cyanine-5 (red).
|
| Organism |
Mus musculus |
| Characteristics |
ES-D3 cell line (CRL-1934)
Transfected with pUb-fluc-mrfp-ttk triple fusion reporter gene.
Age: day 4
Tissue: blastocytes
Strain: 129/Sv mice
|
| Treatment protocol |
PCR amplification and standard cloning techniques were used to insert fluc and mrfp genes from plasmids pCDNA 3.1-CMV-fluc (Promega, Madison, WI) and pCDNA3.1-CMV-mrfp in frame with the ttk gene into the pCDNA3.1-truncated sr39tk. This triple fusion (TF) reporter gene fragment (3.3 kbp) was released from the plasmid with Not1 and BamH1 restriction enzymes before blunt-end ligation into the multiple cloning site of lentiviral transfer vector, FUG, driven by the human ubiquitin-C promoter. Self-inactivating (SIN) lentivirus was prepared by transient transfection of 293T cells. Briefly, pFUG-TF containing the triple fusion reporter gene was co-transfected into 293T cells with HIV-1 packaging vector (δ8.9) and vesicular stomatitis virus G glycoprotein-pseudotyped envelop vector (pVSVG). Lentivirus supernatant was concentrated by sediment centrifugation using a SW29 rotor at 50,000 x g for two hours. Concentrated virus was titered on 293T cells. Murine ES cells were transfected with LV-pUb-fluc-mrfp-ttk at a multiplicity of infection (MOI) of 10.

| Growth protocol |
ES cells were kept in an undifferentiated, pluripotent state by using 1000 IU/ml leukemia inhibitory factor (LIF; Chemicon, ESGRO, ESG1107), and grown on top of murine embryonic fibroblasts feeder layer inactivated by 10 ug/ml of mitomycin C (Sigma, St. Louis). ES cells were cultured on 0.1% gelatin-coated plastic dishes in ES medium containing Dulbecco modified Eagle medium supplemented with 15% fetal calf serum, 0.1 mM beta-mercaptoethanol, 2 mM glutamine, and 0.1 mN non-essential amino acids.

| Hybridization protocol |
Oligoarray control targets and hybridization buffer (Agilent In Situ Hybridization Kit Plus) were added, and samples were applied to microarrays enclosed in Agilent SureHyb-enabled hybridization chambers. After hybridization, slides were washed sequentially with 6x SSC/0.005% Triton X-102 and 0.1x SSC/0.005% Triton X-102 before scanning. Slides were hybridized for 17 h at 60°C in a rotating oven, and washed.
