User:Andy Maloney/Notebook/Lab Notebook of Andy Maloney/2010/07/29/Beta casein test

Yesterday, I found out that none of my casein solutions were supporting motility except for my whole casein. I have narrowed the reasons for this down to the possibility that it was storing them in the -80C freezer. Today, I prepared more beta-PEM and I'm going to try an assay to see if it works. I did send the solution through a 0.2um filter.

First try

Nope...No motility on the slip. I did see a small amount on the slide but I can't use that. I'll wait a few more minutes to see if anything is working.

15 minutes in and still nothing.
