Abstract:
The present invention provides methods and compositions to selectively and directly deliver nanoparticles carrying an active agent to tumor cells. The active agent is internalized by the tumor cells, producing an anti-tumor effect for therapeutic applications and/or depositing a detectable marker for diagnostic applications. The present invention further provides a p53 chimera that circumvents the dominant negative activity of mutant p53 as a therapeutic in the treatment of cancer and reduction of tumor size.
Abstract:
Anti-ErbB2 antibodies are described which bind to an epitope in Domain 1 of ErbB2 and induce cell death via apoptosis. Uses for these antibodies are also described.
Abstract:
A spermatogonial stem cell line that is derived from testes of rats characterized by a desirable genetic background can serve as a source for cells to transplant into male-sterile recipient animals that are immuno-compatible with the spermatogonial line. Rat cells thus transplanted readily develop into fertilization-competent, haploid male gametes, with little or no endogenous sperm competition generated by the testes of the male-sterile recipient. This approach, constituting the first vector system for the use of rat spermatogonial lines from in vitro culture in generating mutant rats on a desired genetic background, effects maximal germline transmission of donor haplotypes from the transplanted spermatogonial cells.

Abstract:
The present invention includes methods for producing nanocrystals of semiconductor material that have specific crystallographic features such as phase and alignment by using a self-assembling biological molecule that has been modified to possess an amino acid oligomer that is capable of specific binding to semi-conductor material. One form of the present invention is a method to construct ordered nanoparticles within the liquid crystal of the self-assembling biological molecule.
Abstract:
A biological magnetic fluid includes a magnetic colloidal disperse phase distributed throughout a liquid dispersion medium. The disperse phase may be made up of magnetic particles coated with cross-linked biologically compatible polymers. The biologically compatible polymers may be connected by way of covalent linkages to biologically active macromolecules. This may be accomplished by covalently linking immunoglobulin to the biologically compatible polymers and then attaching antibodies with predefined specificity to the immunoglobulin. These antibodies may target the magnetic particles on desired cells, for a variety of medical applications. The magnetic particles may be made up of magnetite cores with cobalt or cobalt and boron coatings. In addition magnetic particles may be made of icobalt and boron with the boron being in sufficient concentration to enable radiation activation. The magnetic colloid may be formed by incorporating the biologically compatible polymer into the colloid as the colloid is being formed by reducing a magnetic metallic salt. The colloid is advantageously produced in a multi-stage process in order to achieve very uniform particle sizes. The magnetic colloid may also be made by forming a biologically incompatible magnetic colloid, and slowly adding the colloid to a vigorous I biologically compatible polymer. These biological magnetic fluids are useful, for example, in separating cancerous cells from normal cells in bone marrow transplants.
