Dear colleagues,
We intend to hybridize some DNA microarrays with
fluorescent cDNAs derived from total RNA populations.
We have heard that some people have experienced low
reproducibility in the results of the hybridizations
when using probes derived from total RNA. Is that
common? Any hint or advice on whether using total
RNA or poly A+ mRNA as starting material for probe
labelling will be highly appreciated.
Many thanks in advance.
Regards,
Jose L. Carrasco
