New Sauce

So I went ahead and prepared more PEM. However, I did change the following:

  • Prepared a 10x PEM solution.
  • Filtered through a 200nm filter.
  • Aliquoted into 1mL tubes and put them in the -80C freezer. I'm placing a 6 month shelf life on the PEM so in 6 months, all aliquots will need to be discarded and a fresh solution will need to be made.

I also received my new stock caseins. This means I am going to prepare new solutions containing them. Again, it will be 0.5mg/mL solutions of the various caseins. Filtered and aliquoted and placed in the -80C freezer.
