real time PCR data presentation - presentation of delta CT and copy number (Oct/07/2009 )

Hi folks,
I have been doing real time PCR from the last couple of years, but is stuck up with an issue- I did expression (Taqman) assay for microRNA and presented data as fold change using delta-delta Ct method using standard internal reference as miR48. However one of reviewer of our paper want the data to be presented as delta Ct. What is the best way to to represent data in delta Ct. To me it appear that it will complicate figure and will not be easy to interpret? Any suggestion for best presentation or published paper will be great.
My second question is how can I calculate copy number in microRNA taqman assay?

Thanks for your input.


Any input on data presentation of microRNA- copy number and delta CT please


This doesn't exactly answer your question I think, but I hope you can find it useful:

SUMMARY: Following these guidelines will encourage
better experimental practice, allowing more reliable
and unequivocal interpretation of qPCR results.
