Abstract:
Anions of the formula (I): [DA5M30-xO110-x(M'L)x] in which D is Na , Ca ; A is P, As, Sb, Si, Ge, or combinations thereof, M is W , W , or mixtures thereof; M' is a metallic element from groups 2 to 15 of the periodic table; other than W; L is O , OH , H2O; x is 0-10; and m is 10-20; selectively react with cations Z to afford anions of the formula (II): [ZA5M30-xO110-x(M'L)x] , wherein n is 3 or 4; Z = Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y, or Bi, when n = 3, and Z = Ce, U, Np, Pu, or Am, when n = 4. This reaction may be used for the selective encapsulation of lanthanide or actinide cations, and salts containing anions of formula (II) may be vitrified to form glasses or reduced to form tungsten "bronze" materials suitable for the long-term storage of radioactive lanthanides or actinides.
Abstract:
A recombinantly produced L1 major capsid protein which mimics conformational neutralizing epitopes on human and animal papilloma virions is provided. The recombinant proteins are useful as vaccines protective against papillomavirus infection. Antibodies to the recombinant protein are also provided. Such antibodies are useful in the diagnosis and treatment of viral infection.
Abstract:
The present invention relates to blocking peptides which are capable of binding to ligands for the erbB-2 receptor or the epidermal growth factor receptor (EGFR). The blocking peptides of the invention are used to detect the presence of such ligand molecules. In addition, the blocking peptides are useful in inhibiting or preventing the growth of adenocarcinoma cells which express the erbB-2 receptor or the EGFR.
Abstract:
A process of immortalizing cells with isolated HPV-16, 18, 31, 33 or 35 E6 and E7 genes or the E7 gene alone to produce non-tumorigenic immortalized cell lines which retain the differentiated phenotypic characteristics of the parent cells.

Abstract:
The present invention relates to erbB-2 ligands and function derivatives thereof which are capable of binding to the erbB-2 transmembrane protein but fail to bind to epidermal growth factor receptor. The present invention further pertains to anti-ligand molecules capable of recognizing and binding to the erbB-2 ligand molecule and to screening assays for such ligands. The present invention additionally relates to uses for the erbB-2 ligand, the anti-ligand molecules and the screening assays.
Abstract:
Ligand-label conjugates which are an oligopeptide of 5 to 100 amino acid residues, bonded to a ligand or receptor, which contain a plurality of chemiluminescent or fluorescent labels and a plurality of polyoxoanions of sulfur or phosphorus are useful for immunoassays. Such conjugates are hydrophilic and exhibit very low nonspecific binding, thereby significantly increasing the signal to background ratio in immunoassays.
Abstract:
The invention relates to certain derivatives of mitomycins A and C and the use thereof to treat bacterial infections and to suppress the growth of cancer cells. The invention also relates to processes for the preparation of the mitomycin derivatives of the invention.
Abstract:
A continuous hybridoma cell line, designated 7H8, which secretes a monoclonal antibody (MAb 7H8) of the IgM class and which binds to a protein present in species of the genus Plasmodium. MAb 7H8 also recognizes an antigen (antigen Pf93) unique to P. falciparum. Methods of isolating the substantially pure antigen using the antibody of the present invention are disclosed. MAb 7H8 is well suited for use in immunometric assays. Preferred is a two-sited assay developed with MAb 7H8. Anti-idiotypic and anti anti-idiotypic antibodies to MAb 7H8 are disclosed. The antibodies and antigens of the present invention are useful for immunodiagnostic and immunotherapeutic treatment of malarial diseases of man and animals.
