Abstract: The invention relates to stable compositions of proteins and related methods wherein a protein capable of transitioning into the molten globular state is contacted with a negatively charged lipid vesicle, thereby stabilizing the protein against thermally-induced aggregation, denaturation, and loss of activity. The protein:phospholipid complex directly stabilizes the secondary and tertiary structure of the protein, and the compositions are useful in high temperature formulations and in novel delivery vehicles.

Abstract: The present invention provides nuclease resistant 5'-dithio-modified oligonucleotides that are useful in nucleic acid therapeutics and diagnostics. The novel modified oligonucleotides have at least one 5'-dithioate linkage, wherein both the oxygen atom at the 5'-position (5'-bridging oxygen) and at least one of the non-bridging oxygen atoms of a naturally occurring phosphodiester linkage are independently replaced with a single sulfur atom. The invention also provides a polymer-supported method for making 5'-dithio-modified and 5'-thio-modified oligonucleotides as well as novel monomeric nucleoside and nucleotide intermediates useful in the synthetic method.

Abstract: A method of accelerating corneal wound healing in the corneal anterior stroma and/or improving the quality of wound healing in a mammal comprises: (1) providing an ophthalmically compatible solution of platelet-derived growth factor; and (2) applying the solution to the cornea of a mammal at the time of or subsequent to occurrence of a corneal wound in a quantity sufficient to accelerate clinically detectable healing, the healing being accelerated through proliferation of epithelial cells and/or keratocytes of the cornea stimulated by application of the platelet-derived growth factor to the cornea. The platelet-derived growth factor can be selected from the group consisting of the AA isoform, the AB isoform, the BB isoform, and mixtures thereof. A preferable form of platelet-derived growth factor is a recombinantly-derived refolded B-chain homodimer of 119 amino acids, having the amino acid sequence of SEQ ID NO: 1. The concentration of platelet-derived growth factor in the solution can be from about 10 .mu.

Abstract: The present invention makes possible the catalytic production of sequence specific oligonucleotides through the use of a specially designed template sequence. The reaction can be made to proceed isothermally in the presence of an excess of nucleoside triphosphates, an agent for polymerization, and a cutting agent. Because the process is catalytic with respect to the template sequence, an unlimited amount of oligonucleotide product can theoretically be generated from a single molecule of template. Where the process is initiated by the presence of a nucleic acid target sequence, the method of the present invention can be used for diagnostic purposes as an amplification method to improve sensitivity. Diagnostic sensitivity can be further enhanced by employing a cascade of these template sequences.

Abstract: Processes for isolating and purifying granulocyte colony stimulating factor (G-CSF) from a G-CSF producing microorganism are disclosed. The simplified processes include steps of lysing the microorganism and separating insoluble material containing G-CSF from soluble proteinaceous material; extracting the material with deoxycholate (optionally); solubilizing and oxidizing the G-CSF in the presence of a denaturant solubilizing agent and an oxidizing agent; removing the denaturant solubilizing agent from the G-CSF; subjecting the G-CSF to ion exchange chromatography; and recovering the purified G-CSF; yet excludes other cumbersome purification steps.

Abstract: DNA sequences coding for a TNF-binding protein and for the TNF receptor of which this protein constitutes the soluble domain. The DNA sequences can be used for preparing recombinant DNA molecules in order to produce TNF-binding protein and TNF receptor. With the aid of the TNF receptor or fragments thereof or with the aid of suitable host organisms transformed with recombinant DNA molecules containing the DNA which codes for the TNF receptor or fragments or modifications thereof, it is possible to investigate substances for their interaction with the TNF receptor and/or for their effect on the biological activity of TNF.

Abstract: Disclosed are novel polypeptides possessing part or all of the primary structural conformation and one or more of the biological properties of a mammalian (e.g., human) pluripotent granulocyte colony-stimulating factor ("hpG-CSF") which are characterized in preferred forms by being the product of procaryotic or eucaryotic host expression of an exogenous DNA sequence. Sequences coding for part or all of the sequence of amino acid residues of hpG-CSF or for analogs thereof may be incorporated into autonomously replicating plasmid or viral vectors employed to transform or transfect suitable procaryotic or eucaryotic host cells such as bacteria, yeast or vertebrate cells in culture. Products of expression of the DNA sequences display, e.g., the physical and immunological properties and in vitro biological activities of isolates of hpG-CSF derived from natural sources. Disclosed also are chemically synthesized polypeptides sharing the biochemical and immunological properties of hpG-CSF.
Abstract: Provided herein are methods and compositions relating to the attachment of water soluble polymers to proteins.
