Sample GSM2086454 Query DataSets for GSM2086454
Status Public on Dec 19, 2016
Title HEK bulk rep1
Sample type SRA
Source name HEK293
Organism Homo sapiens
Characteristics cell line: HEK293
Growth protocol HEK293 cells were cultured in DMEM medium supplemented with glutamine and 10% fetal calf serum.
Extracted molecule total RNA
Extraction protocol 1000 HEK-293 cells in 4.5 ul C1 wash buffer (Fluidigm) were lysed with 9 ul of lysis buffer (0.2% w/v Tween 20, 1 U/ul Promega RNAsin RNAse inhibitor, 2 µM reverse transcription primer (AGGGTAATCGTCGGTGTCCAT(30)VN), 2.5 mM dNTPs, 1x C1 loading reagent (Fluidigm), ERCC Spike-In Mix 1 @ 20,000 molecules/cell (Life Technologies). The sample was incubated for 10 min at room temperature followed by 3 min at 70°C and 3 min at 10°C.
Reverse transcription: 18 ul of 1.75 x reverse transcription mix, 8.75 mM DTT, 1.75 M Betaine, 10.5 mM MgCl2, 1.75 uM template switching oligonucleotide (rGrCrArArUrGrArArGrUrCrGrCrArGrGrGrUrUrGN(6)H(4)rGrGrG), 0.5 U/ul Promega RNAsin, 5.5 U/ul Life Technologies Superscript II reverse transcriptase, 1x C1 (Fluidigm) loading reagent were added to the lysed cells and the sample was incubated for 10 min at 25°C, 90 min at 42°C, 15 min at 70°C and kept below 10°C until PCR amplification. PCR amplification and barcoding: One tenth of the reverse transcription (3.15 µl, 100 cells) was mixed with 27 µl 1.15 x Kappa KAPAHiFiHiFi HotStart Ready Mix, 55 nM barcode primer (TGCGGTATCTAAAGCGGTGAG<index>ACACTCTTTCCGCAATGAAGTCGCAGGGTTG, indices are Illumina Truseq indices), 1.1 µM biotinylated PCR primer (Bio-TGCGGTATCTAAAGCGGTGAG), reverse PCR primer (1.1 uM, AGGGTAATCGTCGGTGTCCA). For PCR amplification samples were incubated 3 min at 98°C followed by 18 cycles at 98°C for 20 sec, 64°C for 15 sec, 72°C for 6 min, and a final extension at 72°C for 5 min. Library preparation: PCR products were fragmented by tagmentation with EzTn5 transposase (Epicentre) and Tn5 mosaic end duplexes (upper: 5’-AGA TGT GTA TAA GAG ACA-3’, lower: 5’-PhosCTG TCT CTT ATA CAC ATC T-3’), 5’ terminal fragments were isolated with streptavidin beads and Illumina adapter sequences were added by PCR (Primers: AATGATACGGCGACCACCGAGAT, 0.5 μM; AATGATACGGCGACCACCGAGATCTACACCACAGTTGAGTGCGGTATCTAAAGCGGTGAG, 0.125 μM; CAAGCAGAAGACGGCATACGAGAT, 0.5 μM; CAAGCAGAAGACGGCATACGAGATGTCTCGTGGGCTCGGAGATGTGTATAAGAGACAG, 0.125 μM).
5' selective, oligo-dT-primed RNA-seq based on the SmartSeq technique. Libraries were sequenced with custom sequencing primers. Custom read1 seq. Primer: ACACTCTTTCCGCAATGAAGTCGCAGGGTTG; Custom read2 seq. Primer: GTCTCGTGGGCTCGGAGATGTGTATAAGAGACAG; Custom index seq. Primer: CCACAGTTGAGTGCGGTATCTAAAGCGGTGAG
