Abstract: Antihemophilic factor (AHF), a blood component necessary for clotting of normal whole blood, is extracted from cryoprecipitate containing AHF and fibrinogen as its principal components by: rapidly raising and thereafter lowering the temperature of the cryoprecipitate suspension to selectively denature the fibrinogen in the suspension; and separating the AHF-rich supernatant from the denatured fibrinogen.

Abstract: Disclosed are readily reconstitutable lyophilized fibronectin formulations containing fibronectin, a neutral salt, a carbohydrate and a surface active agent.

Abstract: Antihemophilic factor (AHF), a blood protein component necessary for clotting of normal whole blood, is extracted and concentrated from a cryoprecipitate suspension containing AHF and fibrinogen as its principal components by: selectively precipitating fibrinogen from a water-ethanol solution and removing the ethanol therefrom.

Abstract: Basic aluminum bromides having a basicity of about 5/6 have been found to be readily soluble in cosmetic solvents such as anhydrous ethanol, to have a high degree of compatibility with halogenated hydrocarbons, and to have excellent astringent characteristics. These properties make the 5/6 basic aluminum bromides particularly suitable for use in anti-perspirant compositions, especially the aerosol sprays.

Abstract: A process and improved apparatus are provided for producing macrospherical particles. The particles themselves have increased wall thicknesses and higher densities than particles produced by conventional means and are thus not subject to deep lung penetration. The produced particles are also of controlled (narrow) particle size distribution. Such particles are particularly well adapted for use as anti-perspirants. The process for producing the particles comprises providing a solution containing the materials from which the particles are made, dispersing the solution along a plurality of radially disposed bristles by centrifugal force into discrete liquid droplets and drying the solution droplets in a stream of heated air. The improved apparatus comprises mounting a rotatable atomizer having a plurality of bristles inside a spray drying chamber.

Abstract: The purification of crude calcitonin by subjecting a crude calcitonin material to partition chromatography in which the solvent utilized is a mixture of butanol, a lower aliphatic alcohol, which is ethanol, methanol, or propanol, or mixtures thereof, acetic acid, water and ammonium acetate. In place of acetic acid and ammonium acetate, formic acid and ammonium formate may be used. The crude calcitonin of this invention is of a type known as ultimobronchial calcitonin. This includes calcitonins of the salmon and eel, whether the calcitonins of this type be obtained from natural sources or are prepared by synthesis.

Abstract: The purification of crude calcitonin by subjecting a crude calcitonin material to partition chromatography in which the solvent utilized is a mixture of butanol, a lower alphatic alcohol which is ethanol, methanol, or propanol, or mixtures thereof, acetic acid, water and ammonium acetate. The crude calcitonin of this invention is of a type known as ultimobronchial calcitonin. This includes calcitonins of the salmon and eel, whether the calcitonins of this type be obtained from natural sources or are prepared by synthesis. Preferably, the crude calcitonins of this type, which are purified by the process herein set forth, are obtained by solid phase synthesis in which the amino acid chain is assembled by attaching a resin support to the first amino acid, adding the amino acids one-by-one in the order in which they appear in the natural calcitonin; and finally removing the resin and the protective groups used in the synthesis.

Also resin peptides are disclosed which may be converted to peptides having biological activity and processes for producing said resin peptides and said peptides having biological activity.
