I am Clean!!!

Ken and I had a bet going: If I didn't contaminate my cells by yesterday, Ken could no longer call me a dirty person. The odds were against me... I'm new at cell culture and there's a ton of bacteria and yeast spores floating around. Yet I have successfully maintained the purity of my cells for over a month (I thought I contaminated them about two weeks ago, but the others in the lab said it was just some cell debris). So hooray! Raise a glass of yeasty beer to me -- I am clean!
