3.5 Running Conditions
Run conditions and times are approximate. Conditions may vary depending on water and buffer
conductivity, which vary from one lab setting to the next. Multiply current by the number of gels run.
Table 3.3. Running conditions for SDS-PAGE with Criterion gels in the Criterion cell. Do not run different gel
formulations at the same time.
