This is an SDS-PAGE gel of the protein insulin.
The first lane is the molecular weight standard
marker. The second lane NR is the native, non-
reduced protein (MW 5.7kDa). The third lane is
the protein treated with beta-mercaptoethanol.
Please explain what is shown in the NR lane
versus the R lane.
