Abstract: A method of culturing cells in which the cells are fixed on a polyacrylonitrile surface.

Abstract: A unitized solid phase kit for radioimmunoassay is disclosed. All of the necessary assay reagents are incorporated in a single tube wherein all phases of the assay procedure are performed, requiring only the addition of the patient's sample. Antibody is bound to the tube surface, while labelled antigen is also present but unbound. Storage in the absence of air and water results in the stabilization of the reagents such that the system can be stored for long periods.

Abstract: Water-insoluble, biologically active conjugates for use in a reactor core of a flow-through reactor are prepared by covalently bonding an enzyme directly to a fibrous dialdehyde cellulose such as cotton. Preferably the fibrous cellulose is placed in the reactor core of a flow-through reactor before or after it is treated with periodic acid solution to convert glucose units thereof to units containing dialdehyde groups. Thereafter, an enzyme solution is passed through the resultant dialdehyde cellulose to bind the enzyme to the cellulose.

Abstract: .alpha.,.beta.-Olefinic nitriles, esters and amides are electrolytically carboxylated and dimerized.

Abstract: The present invention relates to an improved process for the preparation of carboxylic acids, specifically by the reaction of ethylenically unsaturated compounds with carbon monoxide and water, in the presence of catalyst compositions essentially comprising iridium compounds and complexes, together with an iodide promoter, the improvement being the provision of at least 50 percent by weight of the iridium in the reaction solution in a highly catalytically active form as a species having infrared absorption bands at 2098 cm.sup.-.sup.1 (vs), 2155 cm.sup.-.sup.1 (w), 2180 cm.sup.-.sup.1 (vw, br). By monitoring the infrared absorption spectra of reacting solutions and following the magnitude of the 2098 cm.sup.-.sup.1 band the operating conditions are adjusted so that this band is present in 50 percent or more concentration relative to the infrared absorption spectral bands of the other iridium species in solution.

Abstract: The present invention relates to a process for the preparation of orthophenylphenol and derivatives thereof, specifically by the reaction of dibenzofuran and its derivatives with hydrogen, at elevated temperatures, in the presence of a catalyst comprised of one or more Group VIII elements dispersed on a porous magnesia support.

Abstract: The propagation and/or maintenance of living cells in vitro is accomplished by attaching and growing cells on one side or surface of a hollow fiber membrane. The attached cells are propagated and/or maintained by passing oxygen through the membrane from the other side and into contact with the cells and simultaneously incubating the cells in a nutrient medium. This method is employed in tissue and cell culturing of altered and unaltered cells which attach to a surface for maintenance and growth.
