摘要:
The present invention relates to second generation monoclonal antibodies having binding specificity to a tumor associated glycoprotein having an approximate molecular weight of >10.sup.6 d ("TAG-72") and human carcinomas and methods for employing the same. Hybridomas producing such antibodies have been prepared.
摘要:
Monoclonal antibodies demonstrating a reactivity with human breast cancer are produced. The hybridoma cultures secreting immunoglobins are produced by hydridoma technology. Splenic lymphocytes of mice, immunized with membrane-enriched fractions of metastatic human mammary carcinoma tissue are fused with the NS-1 non-immunoglobulin-secreting murine myeloma cell line. Screening of immunoglobulin reactivities and double cloning of cultures yielded 11 monoclonal antibodies that demonstrated activities with the surface of human mammary tumor cells and not with the surface of apparently normal human tissues. These monoclonal antibodies aid in the diagnosis, prognosis and treatment of human breast cancer.
摘要:
A method of ameliorating degradation of radiolabeled peptides, especially radiolabeled proteins such as antibodies, by including povidone, also widely known as polyvinylpyrrolidone or PVP, as a radioprotectant in a composition containing a radiolabeled peptide is described. A radioprotectant composition and a stable peptide-radioisotope composition having povidone are also described. Ascorbic acid or other secondary stabilizers may also be added to the compositions to further enhance radioprotection.
