Abstract

The pharmacokinetics, tissue distribution, cell localization, and penetration into tumor xenografts of recombinant [35S]methionine-labeled human alpha interferon (HuIFN-alpha) and murine alpha interferon (MuIFN-alpha) were examined in mice. Both interferons (IFNs) were removed from the blood in a rapid biphasic manner; HuIFN-alpha was cleared faster than MuIFN-alpha. Tissues were analyzed for radioactivity and over 90% of the IFNs was accounted for. The IFNs were detected predominantly in liver, kidney, gastrointestinal tract, pancreas, spleen, and lung. The levels of MuIFN-alpha compared with HuIFN-alpha were greater in the liver, spleen, and lung and less in the kidney, pancreas, and gastr..
