  • Publication number: 20120322730
    Abstract: Methods for increasing and maintaining hematocrit in a mammal comprising administering a hyperglycosylated analog of erythropoietin are disclosed. An analog may be administered less frequently than an equivalent molar amount of recombinant human erythropoietin to obtain a comparable target hematocrit and treat anemia. Alternatively, a lower molar amount of a hyperglycosylated analog may be administered to obtain a comparable target hematocrit and treat anemia. Also disclosed are new hyperglycosylated erythopoietin analogs, methods of production of the analogs, and compositions comprising the analogs.
    Type: Application

  • Patent number: 5106760
    Abstract: Disclosed is a new mouse-mouse hybridoma tumor cell line A.T.C.C. No. HB8209. A monoclonal antibody produced by said cell line is specifically immunologically reactive with erythropoietin and with a polypeptide whose amino acid sequence is substantially duplicative of a sequence extent in erythropoietin. Disclosed also are procedures for isolation of erythropoietin by affinity purification and for quantitative detection of erythropoietin in fluid samples.

  • Patent number: 5013718
    Abstract: A method for reducing stored iron and serum iron in mammals is disclosed. In particular, a mammal having an iron overload disorder is administered a therapeutically effective amount of erythropoietin to increase red blood cell production and the mammal is subsequently phlebotomized to remove the excess red blood cells produced.
