The survival time of rabbit's erythrocytes. I. Elimination of auto- and allogenic erythrocytes radioactively labeled with chromium 51Cr from circulation.

The speed of eliminating allogenic erythrocytes labeled with 51Cr from circulation was examined. Donor's erythrocytes with AFHR phenotype were injected to the recipient with FR phenotype. A fast elimination of allogenic erythrocytes was observed, T 1/2 = 7.6 days. The survival time of autogenic erythrocytes was T 1/2 = 18.2 days. In sera of those rabbits to whom allogenic erythrocytes had been injected, no anti-erythrocyte antibodies against the donor's hemocytes appeared.
