| Extraction protocol |
Nuclear preps, ATAC-seq in embryos and larvae followed previously stablished protocols (Arenas-Mena et al., 2021) https://doi.org/10.1186/s12864-021-07936-0, except that for red spherule cells the lysis buffer during the nuclear prep was supplemented with 0.1 % NP40, 0.1% Tween-20, and 1% BSA, and the density gradient solutions were supplemented with 1% BSA to diminish nuclear shearing. Red spherule cells were purified from the coelomic fluid of adult sea urchins following a previously stablished method (Smith et al., 2019). OmniATAC in 72 hour embryos raised at 15 degrees C and red spherule cells was performed as previously described (Corces et al., 2017).
