pH, conductivity, and electrical current measurements and calculations for common virus elution buffers containing 0.01% SDS.

*20V constant voltage was applied for 30 min in the MBES system. **System resistance was calculated by Ohm’s law R = V/I where current (I) was recorded during the voltage (20V) application. Current density was calculated by the analogous Ohm’s Law equation, electric field strength (E) = current density (J) / conductivity (σ), where current density (J) = current (A) / membrane area (m2) (the membrane area in our system was 4.9 X 10–4 m2). The electric field strength was calculated by equation E = V/d (E = electric field strength, V-voltage, d = distance). pH, conductivity, and electrical current measurements and calculations for common virus elution buffers containing 0.01% SDS.
