Abstract: Disclosed is a method for measuring or detecting inorganic phosphate ion in a sample. In the method, a sample is reacted with a phosphate-binding protein containing (i) an inorganic phosphate ion binding site and (ii) a detectable label that produces a signal whose amplitude changes detectably upon the binding of inorganic phosphate ion to the binding site, under conditions effective to allow binding of phosphate in the sample to the binding site. From a change in signal, the level of inorganic phosphate ion is measured or detected. Also disclosed are phosphate binding proteins for use in the method.

Abstract: The present invention provides a method for eliciting an opioidal analgesia in a living subject using two classes of chemical compositions previously thought to have directly contradictory and physiologically antagonistic roles in the spinal analgesic process. The present methodology relies upon a concurrent administration of an opioid in marginal concentrations in combination with marginal doses of substance P or its related entities which function in a synergistic relationship and mechanism of action. The methodology relies upon a powerful potentiation and enhancement of an opioid-mediated response by the enhancing action of substance P to modulate or eliminate pain and other nociceptive responses, as well as inducing anesthesia.

Abstract: Novel synthetic Arg-Gly-Asp containing peptides which have high affinity and specificity for their receptors by virtue of restrictions on their stereochemical conformation. Such restrictions can be provided by cyclization, by inclusion into a constraining conformational structure such as a helix, by providing an additional chemical structure such as an amide or an enantiomer of a naturally occurring amino acid, or by other methods. In particular, there are provided cyclic peptides having increased affinity and selectivity for the certain receptors over that of linear, Arg-Gly-Asp-containing synthetic peptides.

Abstract: An acrylic rubber composition comprising 100 parts by weight of acrylic rubber containing cross-linkable groups and 2 to 40 parts by weight of tri(2-ethylhexyl) phosphate has quite an unexpected effect on prevention of fixation of its vulcanized rubber moldings to metallic materials or resin moldings when brought into direct contact with the latter due to the presence of tri(2-ethylhexyl) phosphate in the acrylic rubber containing cross-linkable groups.
Abstract: The invention is directed to a method of highly purifying a polypeptide or other biological compounds from a contaminant by crystallization comprising contacting a mixture containing uncrystallized polypeptides and a contaminant with an exogenous nucleating agent, crystallizing the polypeptides, thereby forming at least one crystal of the polypeptide attached to the nucleating agent, the attached crystal being of a high purity, and at least one polypeptide crystal unattached to the nucleating agent, the unattached crystal being of a lower purity than the attached crystal, and separating the crystal attached to the nucleating agent from the crystal unattached to the nucleating agent.

Abstract: Processes for polymerizing ethylene/.alpha.-olefin interpolymer compositions are disclosed. The interpolymer compositions have a controlled composition and a controlled molecular weight distribution. The processes utilize a highly-efficient homogeneous catalyst composition in at least one reactor to produce a first interpolymer having a narrow composition distribution and a narrow molecular weight distribution, and a highly-efficient heterogeneous Ziegler catalyst in at least one other reactor. The reactors can be operated sequentially or separately, depending upon the desired product. The novel compositions have good optical properties (e.g., clarity and haze) and good physical properties (e.g., modulus, yield strength, toughness and tear). Useful products which can be formed from these compositions include film, molded articles and fiber.
