Dear all,

I have flash-frozen mice brains for RNA sequencing and ATAC sequencing. However, in flash-frozen tissues isolating nuclei is problematic. And I can only use one side of the hippocampus, the other I will use for RNA seq.

Is there any optimized protocol that you use for nuclei isolation from flash-frozen tissue? Or shall I need to use at least 2 of the hippocampus to obtain enough nuclei? Or the worst case shall I use cortex instead which contains more cells.

But the most important part how can I isolate nuclei without disturbing nuclei from flash-frozen tissue?

I have ATAC-seq kit from cellbiologics cat: CB6936

Best Regards

Yağız
