In-gel serum Cp activity assays. Serum samples were separated by native gel electrophoresis and subsequently reacted with the substrate (para-Phenylenediamine, pPD) to estimate enzyme activity levels. The site of enzyme activity is represented by the dark bands just below the midpoint of the gel. The blue, diffuse bands at the bottom of the gel are loading dye. Each genotype is represented by samples from 5 individual rats. Purified human Cp protein was used as positive control (CP).
