I was laboring on Labor Day; apparently my cloning experiment didn't work again. The concept is simple enough: cut plasmid/inserted gene, purify, and then glue together. So why has it taken me over two months to do this? (aside from losing the DNA, breaking machines, fighting the Incredible Shrinking Insert...)
Molecular biology (or science in general) at its best (read: textbook figures) is a great concept. We have machines we didn't have a decade ago, protocols that have been refined multiple times, and reagents that can be mass-produced so that they aren't nearly as expensive (although $150 for a tiny bottle of Taq is still way too expensive, for my taste), but even with the technology we have now, everything is far from foolproof. PCRs will just fail for no apparent reason, and the only "logical" explanation was that whatever day the experiment was done on was just a "bad lab day." Likewise, the first sentence in our lab protocol for ligations (where two pieces of DNA are glued together) is "sometimes it works, sometimes it doesn't," making it seem like you should mix the necessary ingredients together, follow the guidelines, and *hope* that it works.
Science is like a religion in itself; sometimes things just happen and nobody knows why. I've been restriction digesting and purifying "my favorite gene," which is supposed to be 500 basepairs long. Somehow after purification, the gene "shrinks" to 300 basepairs. I've ruled out every possiblity I can think of, and there's nothing that can really be done except start over (and maybe whine about it for a while). Yes, cloning sucks, but I suppose I just have to *believe* that whatever I'm doing is the right thing, and that one day after tapping my foot 55 times while wearing a red tshirt and singing along to some given song on my iPod, I'll get my ONE much-needed clone.
Seriously though, howcome superstition isn't more blatant in the research field?
