interesting approach to failure
had a biochemistry practical just this afternoon. long story cut short, one of the steps in doing a western blot was to add blocking buffer into a small dish and put it on a shaker for 1 hour, so that it will block non-specific binding to the nitrocellulose filter.. and my lab partner and i didn't notice it when we added normal buffer instead of blocking buffer until 1 hour was up.
when i eventually made the discovery, we immediately told the lab demonstrator. instead of reprimanding us or demanding us to repeat the step, we were told to proceed normally and see what comes out of it.
i was rather taken aback - i was already feeling guilty as hell for making such a stupid mistake, but now i'm being told that it's not just ok, "it would be interesting, wouldn't it?". we all learnt, theoretically, why the blocking buffer is required, but i haven't really seen what would happen if it wasn't added.. so yep in a sense it is interesting haha.
fast forward another 1.5 hours, instead of seeing a smear of black colour over the entire blot, we saw faint blobs corresponding to the lanes with proteins in it (in non-biologist speak: it's weird lah cos it doesn't correspond with theory). even the demonstrator admitted it was weird, and said maybe the blocking buffer wasn't that important after all. haha.
anyway, today was one of the more enjoyable biochem practs i had, cos we were forced to think through lots of stuff that the demonstrator threw at us instead of blindly following a "recipe" and getting the expected finished products. failure isn't that bad after all! =P
