Disclosed is a method of evaluating stability of a pharmaceutical preparation containing luliconazole. The method includes measuring an amount of production of an SE form of luliconazole represented by following formula (2), an amount of production of a Z form of luliconazole represented by following formula (3) and an amount of production of an amide form of luliconazole represented by following formula (1) after storage under a severe condition or an accelerated condition, and judging that the stability of the pharmaceutical preparation is high if each of the amount of production of the SE form, the amount of production of the Z form and the amount of production of the amide form is not more than 5% by weight with respect to a compounded amount of luliconazole.

The present invention, referred to as Surface-Free Affinity Purification (SFAP), relates to a system and method for purifying low abundance peptides, including digested plasma proteins. SFAP combines the components and processes of Surface-Free Isolation, Specific Competitive Elution, Dual Epitope Isolation and Protective Solvents in the purification of low abundance proteins, all of which may be performed in a single column. This column is a constant volume Diafiltration Column equipped with stirring that can be driven by an HPLC. Digested plasma may be injected into the Diafiltration Column by the HPLC. Immunoglobulins, Specific Competitive Elutants, Protective Solvents are injected in a series of injections that result in the purified peptides bound to the surfaces of a very-low volume hydrophobic reversed phase trap from which they can be easily injected into mass spectrometry detection instruments.

The present disclosure relates to surface proteins of Moraxella catarrhalis and their ability to interact with epithelial cells via cell-associated fibronectin and laminin, and also to their ability to inhibit the complement system. These surface proteins are useful in the preparation of vaccines. The present disclosure also provides peptides interacting with fibronectin, laminin and the complement system.

A system and a method for determining the relative value of a naphtha product includes reforming the naphtha into fractions at a predetermined constant research octane number (RON), conducting PIONA analysis on the reformate, after which modules or steps are performed to assign the feed quality, assign the total liquid yields, assign raw product yields, normalize the assigned raw product yields, assign a value to one or more fractions, and calculate a total value of the naphtha stream. The method is repeated on samples of different crude oils in order to provide relative values at the predetermined RON for comparison purposes.

An apparatus for use in a liquid chromatography system includes a chromatography port and a tubing assembly having a chromatography tube coupled at one end to the chromatography port. The end of the tube has an end face covered with a corrosion-resistant material, for example, gold. The corrosion-resistant nature of the material protects the end of the tube from corrosion or erosion, which improves the quality and reliability of a seal between the end face of the tube and a sealing surface of the port. Alternatively, or in addition to covering the end face of the tube with the corrosion-resistant material, a gasket covered with or made of the corrosion-resistant material can be disposed between the end face of the tube and the port. This gasket extends the reach of the tube to facilitate bottoming out the tube within the port.

Methods and apparatus for controlling interdetector band broadening during the analysis of a sample injected into a chromatography system. A column flow is diluted with a dilution flow after the sample exits the chromatography system, and the diluted sample is analyzed by one or a combination of analysis instruments such as a light scattering detector, refractive index detector, an ultraviolet absorption detector.
