Maybe the RNA in that sample was degraded before retrotranscription? If you still have RNA, you can check its integrity.

Jerry Alan Warden-Smith

is the treatment you are using killing the samples, could there be an error in RNA extraction, is the purity (260/280 ratio) OK?

Deblina Bharadwaj

I am working on breast cancer cell lines. After extraction, the RNA concentration was ok and purity was also good.
