The use of radioactive isotopes in immunological investigations. 3. Further studies on the fate of injected 32P-containing proteins

Abstract
Of P32-containing lipovitellin after intraven. injn. into rabbits, at least 25% was present in the lungs, and 10-15% in the liver, 2 min. after the injn. Over half was present in the lungs of 2 rabbits which died 2 hrs. after the injn. The results for the rabbits killed 21 and 44 hrs. after the injns. suggested that after the initial deposition of lipovitellin in the lungs, with less in the liver, there was a gradual diminution in the amt. held in the lungs and an increase in that deposited in the liver.
