WebCohesin release is not a prerequisite of chromosome compaction. Interphase nuclei were assembled from sperm chromatin in interphase LSS that had been mock-depleted, Plx1-depleted, aurora B-depleted, or Plx1/aurora B-depleted. After 2 h, a half volume of the corresponding CSF extract was added and the mixture was incubated for another 2 h.
