Adventures in protein land

I’m not a protein biologist.

I wouldn’t usually describe myself as a geneticist either, unless trying to clarify what it is that I spend my time doing, in the same way that for years I would describe myself as playing the violin rather than as a violinist, because that seemed to indicate some level of skill that I didn’t feel I yet had.

But I’m definitely not a protein biologist, because I did no protein work as an undergrad, and I didn’t sign up to do a protein based PhD, and there’s only one post doc in the lab who has the first clue about proteins and – while she is possibly the most helpful post doc ever to cross my academic path – there’s only so much help someone can give you when you don’t know what questions to ask.

Yet in spite of this, I appear to be in a situation where doing protein work is inevitable. A few months ago I learned about PAGE gels and Coomassie blue staining and Western blots. Now, I must actually start extracting protein from real live plants, as opposed to my nice-n-easy-burst-like-a-bubble-E. coli. It turns out that this is rather more complicated than I had hoped.  Continue reading

The Ramen Diaries: Part 8 – Protein Extractions

After a week off with flu, there’s just no avoiding it. Today I have to get back in the lab and do my first ever protein extractions from a plant. I have a protocol, that I am assured works, and no reason to suspect it doesn’t. And I have been sat here for 54 minutes doing admin instead of even going to the greenhouse to get my plants. Looks like the stage fright is back. Le sigh….
