Fractionation of the serum proteins by cellulose acetate electrophoresis. Cellulose acetate electrophoresis was performed with serum obtained from controls, mono- and poly-arthritic rats, as described in the “Methods” section. a Typical sample of dried electrophoresis strips for each experimental condition. b Levels of total proteins and electrophoretic bands obtained by densitometry of the dried strips. The results are expressed as mg protein (ml serum)⁻¹ and the values are the mean ± SE of the mean of four animals for each experimental condition. *p < 0.05 indicates statistical difference from the controls and ^#p < 0.05 from the monoarthritic condition
