After the RNA isolation from fresh colorectal cancer biopsies, I dose my RNA's concentration, and I find about 3000µg/ml. In RT, I take 5µl of my RNA at 1ug :
Ci= 3000 µg/ml
Cf= 200 µg/ml (1µg/5µl)
Vf= 50ul
then I found Ci= 3,3 µl from my RNA + 46,7 H2O
I would ask if someone knows if I can use a concentration of RNA higher than 1µg??
Thanks.
