RNA extraction from skin samples

[VL Shires]

I have just started a PhD and have been trying to extract total RNA from 
skin samples from mice for RT-PCR analysis of cytokines.  I know that 
other people have managed to do this type of analysis before as there is 
published data.  My RT-PCR step is fine as my positive controls are 
working beautifully but the message from the skin samples is at best very 
weak.  So if any one has any suggestions re: more efficient extraction 
methods (currently using Guanidium, CsCl gradient and phenol method) or any 
other helpful tips for this work I would be very grateful if they could get 
in touch.

Thanks,
