Abstract: The present invention relates to methods, systems, and kits for intoxicating cells, neuronal and non-neuronal cells, with a toxin or fragment thereof. This is done by subjecting toxin substrate and a lipid or polymeric carrier (e.g., DNA uptake facilitating agent) to one or more cells for use in cell based assays. In an aspect, the methods of the present invention allow for high throughput assays and, as such, for the evaluation of drug candidates.

Abstract: Methods, compositions and kits are provided for treating a subject exposed to or at risk for exposure to a disease agent using a pharmaceutical composition including at least one recombinant heteromultimeric neutralizing binding protein including two or multiple binding regions, such that the binding regions are not identical, and each binding region specifically binds a non-overlapping portion of the disease agent, thereby treating the subject for exposure to the disease agent. In a related embodiment, the heteromultimeric neutralizing binding protein includes two or multiple binding regions that neutralize a plurality of disease agents. In certain embodiments, the disease agent includes a bacterium, a bacterial protein, a virus, a viral protein, a cancer cell, and a protein or molecule produced therefrom. In certain embodiments, the disease agent is a plurality of different disease agents.

Abstract: The present invention relates to methods and systems for administering antibody therapeutic agents. The methods include administering one or more (e.g., two or three) binding agents, wherein each of the binding agents has one or more monomers that have a binding region that is specific to a portion of a disease agent and one or more copies of a tag. The binding agents can be specific to one or more portions of the same or different disease agents. The tag is the same for each of the binding agents. The methods include administering an anti-tag antibody, wherein the anti-tag antibody has an anti-tag region that is specific to the tag, and can have an immunoglobulin (e.g., IgA, IgD, IgE, IgG, and IgM). Disease agents include bacteria, bacterial proteins, viruses, viral proteins, cancer cells, and proteins or toxins produced therefrom or from other sources such as snakes, insects, plants, etc.

Abstract: The present invention relates to a designer or recombinant ubiquitin ligase molecule that includes an antibody fragment that is specific for a toxin active fragment, wherein the toxin active fragment is an enzymatically active fragment of one or more toxins or toxin serotypes; and an E3-ligase domain that comprises an E3-ligase or polypeptide that facilitates E2-mediated ubiquitination of the toxin active fragment. In an embodiment, the composition further includes a delivery system that allow the designer ubiquitin ligase to enter the cell. The present invention further includes methods for treating an individual intoxicated with a toxin by administering the designer ubiquitin ligase of the present invention.

Abstract: Disclosed are proteins derived from the sand fly Lutzomyia longipalpis capable of inducing vasodilation in mammals and data characterizing the proteins and nucleic acids encoding the proteins. Also disclosed is a method for temporarily inactivating the immune system in a mammal comprising administering to the mammal the Lutzomyia protein, CGRP, calcitonin, or active immune suppressing analogs thereof.

Abstract: A new improved glycoprotein having erythropoietin-type activity is disclosed. The substrate is characterized by amino acid sequence substantially identical to the amino acid sequence of native human erythropoietin wherein the methionine-54 is replaced with leucine. DNA encoding for the EPO-substance and expression vectors incorporating the same are disclosed. Therapeutic compositions and methods for treatment of anemic conditions are described.

Abstract: High yields of active Factor IX are produced by culturing a CHO cell line transfected with chromosomally-integrated Factor IX cDNA in medium to which vitamin K is added.
