Can isolated nuclei suspensions be frozen for later use?

2026-06-23

instagram Facebook Twitter tiktok

Answer:
Not recommended.

Freezing isolated nuclei typically causes severe nuclear membrane damage, leading to:

  • Rapid loss of ATAC signal quality
  • Reduced signal-to-noise ratio
  • Additional RNA degradation

After nuclei isolation, transposition reactions should ideally begin immediately and preferably within 1 hour.

If sample storage is unavoidable, intact tissue should be cryopreserved before nuclei isolation rather than freezing purified nuclei suspensions.
