Sample type |
SRA |
|
|
Source name |
bone marrow progenitor cells
|
Organism |
Mus musculus |
Characteristics |
cell type: GFP-NFIL3 negative BM strain: C57BL/6 chip or cut&run antibody: NFIL3 (Santa Cruz Biotechnology, sc-9550X, Lot# G0815)
|
Treatment protocol |
Nfil3GFP/GFP mice were injected once daily, subcutaneously, with 10 mg recombinant Flt-3L-Ig (BE0098; Bio X Cell) for three consecutive days to expand GFP-NFIL3+ DC progenitor cell numbers.
|
Growth protocol |
BM cells were isolated from Nfil3GFP/GFP mice and CD3-, CD19-, B220-, CD105-, TER-119-, Ly-6G-, CD4-, CD8b-, CD11b-, Ly-6C- and MHCII-expressing lineage-committed cells were depleted. GFP-NFIL3 negative BM and GFP-NFIL3 positive BM cells were sort purified.

Extracted molecule |
genomic DNA |
Extraction protocol |
0.7 million fresh sort purified cells were adsorbed to activated Concanavalin A (ConA) beads, permeabilized with 0.01% digitonin, and incubated with 0.5 mg goat-anti-NFIL3 antibody overnight at 4 °C. After antibody binding, the targete-DNA complex is cleaved by the Protein A/Protein G-Micrococcal Nuclease (pAG-MNase) for 2 hours at 4 °C. 0.05ng E. coli Spike-in DNA was added before releasing CUT&RUN fragments at 37°C for 10 min. The CUT&RUN enriched DNA is purified from the supernatant. Libraries were prepared with a NEBNext Ultra II DNA Library Prep Kit for Illumina (New England Biolabs) and cleaned-up with AMPureXP.
