mRNA increase and protein expression - (Oct/25/2011 )

Hi Enthusiast!!
Thanks a lot for your comments!
Regarding the half-life, I can´t measure at a different time, because I work with human placenta obtained at birth!!! I know that i have only a "photograph" of this time...
Also, I would expect that different mRNA-proteins have different half-life, but I've these results in at least 4 different mRNA-proteins...
