Above are the results of Bradford anlysis of the post-dialysis protein solutions. The data does not look good, and suggests that there is no protein present. The most likely reason for such data is that the wrong side of the dialysis chamber was tested using Bradford Analysis. The samples are still stored from this experiment, so it may be possible to re-run this UV-Vis experiment. | Above are the results of Bradford anlysis of the post-dialysis protein solutions.

Run Bradford Analysis on Post-Dialysis SolutionsPost-dialysis solutions from all of the wells in the dialysis chamber were analyzed using UV-Vis using the following protocol:
Run Ca2+ ISE on Dialyed Samples
DataCa2+ ISE DataAbove are the final concentrations of Ca2+ in the post-dialysis solutions. The final two initial concentrations do not give good data as the final concentrations measured between the protein and ion side add to a greater concentration of ions than was originally present in the initial solution. These two data points should be disregarded and Lysozyme should be dialyzed against additional concentrations of Calcium ions in order to form a better curve later. Bradford DataAbove are the results of Bradford anlysis of the post-dialysis protein solutions. The data does not look good, and suggests that there is no protein present. The most likely reason for such data is that the wrong side of the dialysis chamber was tested using Bradford Analysis. The samples are still stored from this experiment, so it may be possible to re-run this UV-Vis experiment.
