Study: Whole-organism C. elegans L2 GRH-1 ChIP-seq (experiment 1 of 2)
show Abstracthide Abstract
We performed ChIP-seq to determine chromatin regions binding Transcription Factor GRH-1, and thereby potential binding motifs and sites thereof, in C. elegans (larval stage 2) whole organisms. Overall design: One sample was used as "input", ie non-specific pulldown. 3 GRH-1-specific samples were generated, using 3 different salt concentrations for protocol optimisation and potential replication. Samples were collected at two time points to broadly cover the L2 stage, before pooling.
Sample: exp1, 1M ChIP

Strategy: ChIP-Seq

Selection: ChIP
Layout: SINGLE
Construction protocol: 5 million animals were collected in PBS + PI + PMSF 1mM at 15 hours and 19 hours after plating (ie 2 timepoints within L2) and popcorn was created from resuspended larvae mix. Popcorn from both time points were pooled and lysate was prepared by grinding the popcorn, crosslinking with 1.1% formaldehyde and sonication with a Diagnode Biorupter Pico. For the chromatin immuno-precipitation, 50 uL of protein G Dynabeads (10003D, ThermoFisher Scientific) were incubated with 5 ug of anti-GFP antibody (ab290, Abcam) for 4 hours rotating at 4°C. 100 ug of chromatin was added, and incubated over night at 4°C rotating. Beads were washed and the elute was treated with proteinase K and RNaseA, and DNA was purified using Zymo ChIP Concentrator Kit. Libraries were prepared using the ChIP-seq NEB Ultra protocol, and sequenced using the Illumina 50-Cycle Single-End reads protocol on the HiSeq2500.
