Characteristics |
strain: C57BL/6 age: 8-week-old genotype/variation: control cell type: follicular B cells treatment: stimulated with LPS/IL-4 for 25.5hr in B cell media

Extracted molecule |
total RNA |
Extraction protocol |
Purified ribosome footprints were extracted using miRNeasy Kit from Qiagen (cat. no. 217004) RNA libraries were prepared for sequencing using ribosome profiling libary prep protocol (Ingolia et al., Nature Protocol 2012). Indexed footprint library was generated with 4 or 6 cycles of PCR using index library primers, and avoided broad, slower migrating smear bands.

Ribosome footprints FoB25.5h_WTrep3
|
Data processing |
Illumina Casava1.8.2 software used for basecalling. The raw sequencing data were separated into individual samples using index primer sequences. Then, the miRNA linker and the first nucleotide of 5'-end are clipped and trimmed using fastx toolkit (http://hannonlab.cshl.edu/fastx_toolkit/). Reads obtained from rRNAs are discarded using Bowtie v1.0.0 using 23 seed flag (Langmead et al, 2009). Illumina iGenome (mm10) were used as a reference. The non-rRNA sequencing reads were further aligned to the reference genome (mm10) using TopHat v2.0.11 with added option, "no-novel-juncs" Only the perfect-match aligned reads were further extracted from accepted hits (accepted_hits.bam) to reduce potential noise derived from relatively short ribosome footprint length (Ingolia et al, 2012). Differential ribosome footprint levels in different genotypes were further quantified using Cuffdiff (v 2.2.1) To accept only translated genes, we took cut-off of ribosome footprints at fragments per kilobase per million (FPKM) > 1, and only selected genes that were quantified in all three biological replicates.
