Sample GSM1521347 Query DataSets for GSM1521347
Status Public on Nov 24, 2014
Title chip 3991 replicate A sort S0
Sample type SRA
Source name ERC Cell Line Infected with Chip 3991
Organism synthetic construct
Characteristics host organism: Gallus gallus
host cell line: ERC
shRNA type: shRNA Guide Sequences
Treatment protocol From Fellmann et al Mol Cell 2011: ERC reporter cells were infected with pSENSOR libraries at singly copy and sorted in iterative cycles, either after treatment with Dox and G418 (500 μg/ml) for 6–7 days (OnDox) or after Dox and G418 withdrawal for 6–7 days (OffDox). The gating was guided by reference cells transduced with small pools of potent (Top5) and weak (Bottom5) control shRNA-Sensor constructs.
Growth protocol DMEM supplemented with 10% FBS, 1 mM sodium pyruvate, 100 U/ml penicillin, and 100 μg/ml streptomycin
Extracted molecule genomic DNA
Extraction protocol Genomic DNA was isolated using the QIAamp DNA Blood Maxi Kit (Qiagen)
Libraries were constructed by PCR of the shRNA guides from the infected cells genomes. PCR primers were tailed with illumina addapter sequences.
Library strategy OTHER
Library source genomic
Library selection other
Instrument model Illumina Genome Analyzer II
Data processing 1: Reads were aligned to sensor construct target sequences using bowtie (allowing zero mismatches)
2: Reads were quantified with unix command uniq -c
3: Reads were normalized to have a sum of 1 for each sample.
4: Samples corresponding to sorts S1,S3 and S5 were log2 normalize by their corresopnding S0 reads.
5: Corresponding sorts were averaged across replicates
6: For each chip a matrix was constructed where rows correspond to shRNAs/targets and columns to the normalized values of sorts S1, S3 and S5. This is taken as the shRNA efficacy measurment.
Supplementary_files_format_and_content: Initial_Sensor_Summary has three fields for every construct assayed. Field 1: Human gene the shRNA is targeting. Field 2: The shRNA guide sequence. Field 3: The shRNA target sequence. Field 4: The calculated shRNA efficacy score
