Title |
E12.5 Kidney Single Cell RNA-Seq-cell 44 |
Sample type |
SRA |
|
|
Source name |
Analysis of single cells from E12.5 kidneys
|
Organism |
Mus musculus |
Characteristics |
genotype: wild type component sampled: metanephros theiler stage: TS20 age: 12.5 dpc strain: mixed background Sex: pooled male and female pooled sample: unspecified
|
Treatment protocol |
1. E12.5 embryonic kidneys are dissected in ice-cold PBS and pooled into a 1.5ml nuclease-free tube. 2. Dissociate with 200ul Trypsin 0.5% at 37C for 5 minutes with trituration. 3. Add 1ml ice-cold 10% FBS/PBS. 4. Spin down at 2300rpm for 5 minutes. 5. Re-suspend in 1ml ice-cold 1% FBS/PBS. 6. Filter using 20um mesh filter - rinse with 4ml 1% FBS/PBS to remove clumps and debris. 7. Centrifuge at 2300rpm for 5 minutes and re-suspend in appropriate volume 1% FBS/PBS to yield a concentration of 300,000 cells/ml. Verify cell concentration using haemocytometer. 8. Load into Fluidigm for single cell analysis.

Extraction protocol |
The single cell suspension was loaded into the Fluidigm C1 machine. The cell capture, wash and lysis were carried out according to standard Fluidigm protocols. Following capture individual capture sites were examined microscopically to record which chambers received single cells. The reverse transcription and amplification reactions were carried out using standard Fluidigm (C1 Single-Cell Auto Prep System) methods with the SMARTer Ultra Low Input RNA for Illumina Sequencing Kit (Clontech) and the Advantage 2 PCR Kit (Clontech). The libraries were prepared with the Nextera XT DNA Sample Preparation Kit (Illumina Technologies). 1ng cDNA was suspended in Tagment DNA Buffer, and tagmentation (fragmentation and tagging with the adaptors) was performed with the Nextera enzyme (Tagment DNA Enzyme). Tagged and fragmented cDNA was purified with DNA Clean & Concentrator-5 (Zymo Research). The libraries were prepared by PCR with Nextera PCR Master Mix, PCR Primer Cocktail, 2 Nextera Indexes (Index 1 (i7) N701-N712 & Index 2(i5) N501-N508) and barcoded according to the following program: one cycle 98C for 30s, 5 cycles of 98C for 10s, 63C for 30s, 72C for 3min. The purified DNA was captured on an Illumina flow cell for cluster generation. Libraries were sequenced on the Illumina HiSeq2500 following the manufacturer's protocols.

|
Data processing |
Processing step: Samples were aligned to the mm9 genome using TopHat v1.4.1. Known junctions from the RefSeq database were provided to TopHat with the -G option. The generation of RPKM data was carried out using GeneSpring 12.6.1-GX-NGS-RV (Agilent Technologies). Read density (nRPKM) in GeneSpring NGS is computed as the normalized read count (DESeq) per kilo base of exon model per Million reads. This is similar to the standard RPKM used in the literature except that it is computed on the normalized read count rather than on the raw read count. Genome build: mm9 data file format and content: Excel spreadsheet including RPKM values for each Sample in Series.
