I am trying to extract RNA from cells collected from urine samples (ie
exfoliated bladder cells). I am not having much luck. I am pretty sure
the extraction technique is working, because I am able to extract RNA
from other samples. I am starting to wonder whether there is extractable
RNA in these cells, or whether they are so past it already that their
RNA is already degraded. Has anyone else successfully extracted RNA from
exfoliated bladder cells?
