·         Formaldehyde-Agarose Gels (Beverly Faulkner-Jones)

Agarose gels have a smaller resolving power than polyacrylamide gels but a greater range of separation - from 200 bp to >50 kb using standard gels and electrophoresis equipment. RNAs up to 10 000 kb can be separated in agarose gels using pulsed field gel electrophoresis.

·         Denaturing polyacrylamide gel electrophoresis of RNA (Beverly Faulkner-Jones)
Polyacrylamide gels have enough resolving power to separate fragments differing by only one base pair in size, but their range is ~ 5 to 1000 bp. They are much more difficult to handle than agarose gels.

·         Recovery of RNA fragments from polyacrylamide gels (Beverly Faulkner-Jones)
The best method is the crush and soak method. It can be sued to isolate single-stranded RNA from denaturing gels. The RNA is of high purity but the method is long and inefficient if long transcripts are to be recovered (cf. less than 30% of DNA greater than 3 kb is recovered).
