The high autoantibody activity of antibodies to rat skeletal muscle glycogen phosphorylase b produced in rabbits.
Antibodies to rat skeletal muscle glycogen phosphorylase b were prepared in six rabbits by weekly injection of the enzyme emulsified with complete Freund's adjuvant. All the antiserum preparations showed high autoantibody activities to react with the rabbit muscle enzyme in both inhibition of enzyme activity and precipitation. In Ouchterlony double diffusion in agar, the antiserum preparations were precipitable to give a distinct spur between the two precipitin lines formed with rat and rabbit enzymes. When the autoantibody index was taken as per cent cross-reactivity of rabbit enzyme with rat enzyme, the autoantibody indices of inhibition and precipitation of one of the antiserum preparations were as high as 98% and 52.3%, respectively.
