We would like to preserve RNA from mammal blood samples. Unfortunately the only product I am aware is RNA Later and it is very very expensive for our limited budget. Any ideas? Thank you very much
To make a homemade alternative for RNA Later, mix 75% ethanol with 25% diethyl pyrocarbonate (DEPC)-treated water. Keep it at -20°C. Use this solution to immerse and preserve biological samples for RNA stabilization.
