Table A.2. Standard running conditions for native PAGE with one (1) Mini-PROTEAN TGX gel in the Mini-PROTEAN
Tetra cell . Run conditions and times are approximate and assume a constant voltage of 200 V. When running more than one
gel, current will differ but temperature and run time should be close to those listed.
