Why do we have to use MOPS and formaldehyde in RNA electrophoresis - (Aug/03/2006 )

Hello everyone!

I am a Vietnamese student.
Would you please tell me why do we have to use MOPS
and formaldehyde in RNA electrophoresis.

Thank you so much!

Formaldehyde is used because it unfolds the secondary structure of the RNA. MOPS should do the same.
Please, take care with formaldehyde because it is toxic and you shoudn't inhale it
