3. Protein quantification: It is important to know the concentration of protein sample being loaded onto an SDS-PAGE gel so that similar quantities can be loaded onto subsequent gels and a comparison across the gels can be made. It also helps in avoiding experimental artifacts and allows analysis of the gel in a biological context. Serum protein analysis 49 METHODS Bonner & Fogden (1971), analysed the blood serum of sixteen Orkney Grey seals using starch- agar gels at pH 9.1, starch gels at pH 9.2 and cellulose acetate membranes at pH 8.6. They found that most of the samples displayed a single banded pattern, while two showed an additional slow- moving band.
