Lea,
I know you’re doing DesBio. I didn’t see your first few posts, so I don’t know if anyone shared this with you or not. You may have already searched the forum and seen it. There was a discussion on DesBio a few years back that had a lot of information and experiences shared. I found the thread. It’s 4 pages long. Here’s the link in case you’re interested and haven’t seen it already.
