array name > Troubleshooting > FRUs Smart battery chip as it commonly is seen. However, if the tissue dissociation protocol is not optimized, then it may be better to snap-freeze the tissue whole. Click Reset Equipment Plug the Lightning to USB cable that came with your. If a well-optimized tissue dissociation protocol is already available that yields >90% viable cells with no cell type bias, then dissociation followed by cryopreservation is preferred. snap-freezing whole tissue) would depend on the sample type. The choice of one method over the other(dissociating and then cryopreserving vs. Please refer to this article: How do you isolate nuclei from snap-frozen tissue for 3’ gene expression profiling? In this case, it is recommended to extract nuclei from the snap-frozen tissue. Prepare all of your buffers with protease. If the tissue is frozen whole, isolating viable single cells after thawing is more challenging. Turn on sonifiers and cooling system allow system to reach -2C before shearing. When freezing cells, we recommend starting with at least 1 million total cells to recover sufficient numbers post-thaw since almost half of the cells may be lost in the freeze-thaw process and during the wash and centrifugation steps. Cells can then be cryopreserved in a suitable freezing medium. Before freezing, the tissue could be dissociated into a single-cell suspension. Question: Are fresh-frozen tissue samples compatible with Single Cell RNA sequencing?Īnswer: If it is not feasible to process fresh tissue, fresh-frozen tissue samples can be used for Single Cell RNA sequencing.
