detergent

Yesterday I used the Melvern to determine particle size and zeta-potential for BSA in DI-water. For the particle sizing I used a concentration of 2mg/mL but I had to increase the concentration to 10mg/mL in order to get an accurate zeta-potential measurment. As shown above the size measurements provided an average diameter of approximately 5.6nm….

This is the first post I have made with respect to the project proposed by Mark Dumont of the department of Biochemistry and Biophysics. As a reminder of the scope of the project Mark has shown an interest in using our pnc-Si membranes to separate detergent from trans-membrane proteins during the process of preparing samples…
