Well this has been a great week. Here's what we accomplished:
1. Travis ran a Mg concentrations series on some nucleosome samples. He, for the first time in Andresen lab history, saw the condensation and precipitation of nucleosomes. I don't have his data right now, but perhaps he can upload it and explain what happened. Next week he will be running the same experiment, only this time using equilibrium dialysis. This is exciting as this is the method we will eventually use for our nucleosome experiments.
2. John is really honing in on our uncertainties in our ICP-OES measurements. He's run somewhere around 30 samples total so that we have been slowly able to eliminate one possible cause after another. The last batch of samples he made before going home this afternoon should either confirm or eliminate our final couple of theories on the source of our ~5% systematic error. If he eliminates all of our explanations, then I guess it's back to the drawing board.
3. I've gotten the OK to collect chicken blood. Around 10am this Tuesday, I should be in Waynesboro, face-to-face with a pretty unhappy chicken.
And that's all for this week. Couldn't have asked for a better one. (Except for that darn UV detector that still hasn't shipped from Fisher...)
