Hi everyone,

I have extracted RNA several times with SV total (Promega), Triazol and Triazol followed by SV total.

The Promega kit and Triazol followed by Promega kit, those 2 ways gave fine purity, not degraded RNA on gel but very low concentration (60 and 70 ng/μl), and Triazol gave fine purity and very high concentration but degraded RNA on gel (Tall Smear and not clear 2 bands).

My Questions are:

1. Which way is best for high purity, concentrated and not degraded RNA?

2. What should I do to get high concentration of RNA?

3. Actually I prefer Triazol, how I can get not degraded RNA?

Thank you.
