<strong>Migration patterns of Broad Range Prestained Protein Ladder in different electrophoretic conditions</strong><br>The apparent molecular weight of each protein (kDa) has been determined by calibration of each protein against an unstained protein ladder in specific electrophoresis conditions.
Note on apparent molecular weights: Depending upon the gel type used, the coupling of a charged dye molecule to a protein marker alters the overall charge of the protein and thus its mobility in a gel. This results in differences in observed molecular weight of the protein markers between different gel types as shown in figure.
2 ul protein ladders were loaded in the 8%-18% gel, then electrophoresed and transformed into the PVDF membrane. After blocking, this dual-channel image was taken directly by the Bio-Rad ChemiDoc MP Imaging System in the 550 nm (for 75k Da and 310 kDa) and 680 nm (except 75k Da and 310 kDa) range.
