Immunological properties of erythrocyte catalase in Japanese type acatalasemia.

The reaction between acatalasemia hemolysate and anti-normal erythrocyte catalase IgG gave a precipitin line which was interrupted by a normal precipitin line, in the double immunodiffusion method. Hypocatalasemia hemolysate revealed two precipitin lines, one completely, the other partially, fused with a normal precipitin line. No immunological reactions between fresh hemolysates of acatalasemia, hypocatalasemia and normal erythrocytes and antihuman C-reactive protein serum were observed, but the lysates stored for 4 weeks in an ice cold water bath reacted slightly with this antiserum.
