September 17, 2014Calibration Curves for pH and Conductivity ContinuedThe remaining pH and conductivity measurements for serial dilutions 50x, 100x, 200x, 500x of the 50 mM NaCl solution, as well as for all 8 serial dilutions of the 50 mM glycine solution, were found:
The following graphs demonstrate the collected data:

Dialysis Sample StorageThe five dialysis samples prepared yesterday "soaked" overnight. Consequently, today they were removed from their respective soaks & tubing and placed in Falcon tubes for storage during the weekend, to be analyzed via Bradford assay next week. NOTE: The lysozyme stock sample in 25K MWCO dialysis tubing (glycine soak) was spilled during transfer. The data for this sample will be obtained from another group. |
