Storage of samples prior to RNA isolation

Working with RNA is always a tricky thing. It's probably the thing I am most anal retentive about when it comes to the lab. Our lab not only has entire areas set aside for RNA work, we also have reserved pipetors (with tips) and reagents for the practice as well. Halting RNA degradation during an experiment is something we've also spent a lot of time considering. Since bacteria are pretty adept at responding rapidly to their environment, simply sticking a sample in a freezer won't do the trick. As those cells cool down, they will go into cold shock and the transcription profiles will start to change. RNA synthesis needs to halt immediately, as does RNA degradation (those molecules typically have a half-life of less than 120 seconds). This acetone/ethanol protocol does the trick in our hands. It's as quick and as cheap a solution as we've been able to come to. Not everyone can afford Ambion's RNALater by the gallon.

Nice tip, I'm definitely taking this one to heart since I do a bunch of RNA isolation.

It will be great that you will be available there to accomodate the players but yo also need rest as you have been working all the year long and need Osteopath Sydney CBD to get yourself free of pains and inflammation.
