Protocols
These protocols are updated relatively often (annually or so), and as we publish papers containing new methods the protocols should appear on this page.
We have published detailed versions of our protocols for Northern blotting (Methods Mol Biol. 2020;2063:83-103) and PFGE analysis (Methods Mol Biol. 2013;1054:195-207).

Which RNA prep do I use? Probably hot phenol, but GTC can be better for ribosome analysis. The GTC miniprep is the fastest and most consistent if you need to prep many samples and aren't too fussy about perfect quantification. With few samples, consider mirVANA kits – these produce beautiful RNA but are expensive
