Rabbit antisera were prepared against crystalline chicken lysozyme and characterized by immunodiffusion, immunoelectrophoresis, inhibition of enzyme activity, and quantitative micro-complement fixation. Lysozyme was purified by Sephadex G-75 chromatography from the egg whites of 17 species of birds in the order Galliformes and was tested for reactivity with anti-chicken lysozyme. The chicken an...
