Title |
Pax5 preB input control |
Sample type |
SRA |
|
|
Source name |
RAG-/-µ+ pre-B cells
|
Organism |
Mus musculus |
Characteristics |
strain: C57BL/6 tissue: Pre-B cells
|
Growth protocol |
Bone marrow and spleen cells were isolated from 6 to 14 wk old C57BL/6 mice, including both males and females.
|
Extracted molecule |
genomic DNA |
Extraction protocol |
For bone marrow subset purification we used B6 RAG-/- µ+ mice bearing a rearranged IgM transgene were used to obtain pre-B cells. For each sample 1 - 10 ng of IP material or input control sample was prepared into sequencing libraries using the NEBNext Ultra DNA Library Prep Kit for Illumina following manufacturers protocol. Samples were amplified using 18 cycles of PCR and then size selected on 2% EX agarose gels (Thermo Fisher) and bands cut at 300bps (+ 25 bps) and cleaned up using DNA Clean & Concentrator-25 (Zymo Research). The prepared libraries were loaded onto an Illumina HiSeq2000 for single-end base reads with 7 bases of the index read. Data was processed to generate Fastq files using CASAVA 1.8 and demultiplexed based on index sequences.

Data processing |
Duplicated reads were removed before mapping. Experimental and input control fastaq tags were aligned to the mouse reference genome (mm9) using Bowtie 0.12.9. Alignment parameters used:-a -v 2 -m 3 --best --strata All reads mapping with their best alignment score at more than 3 sites in the genome were discarded. Confident peaks were called using MACS (version 1.4.2), with FDR<= 1% and the default p value (1E-5). Genome_build: mm9 Supplementary_files_format_and_content: file format: bed; content: confident peaks (as called by MACS).
