you can still interpret the data depending on the locations of your -s-s-
linkages in the protein. DTT or 2-ME are reducing agents that break th -s-s-
bons to form -SH bonds. For eg: if you have antibody sample, the reduced Ab
runs as two bands of ~55kDa and 25kDa while the non-reduced sample will run
at ~150 kDa.
Hope that helps
