Abstract: Disclosed is a method for producing proteins having factor VIII procoagulant activity in serum-free medium by in vitro culturing of mammalian cells, wherein the serum-free medium contains an inhibitor against the protease released from cultured cells. In accordance with this invention, the inhibitor can protect the cleavage of a target protein during cultivation and increase homogeneity of a target molecule, wherein the inhibitor can be a dextran sulfate. This invention also relates to a method of purifying target molecules from the culture medium containing both a target molecule and selected inhibitors by affinity chromatography.

Abstract: A developing unit of a liquid electrophotographic printer includes a developing roller, for forming a development gap with a photoreceptor web where developer is filled and developing an electrostatic latent image formed on the photoreceptor web, a squeegee roller installed at the rear end of the developing roller for closely pressing the photoreceptor web to squeegee surplus developer, and a cleaning mechanism for removing toner particles of the developer adhering to a surface of the squeegee roller using an electrical force. Since the toner particles adhering to the squeegee roller are removed, contamination of a developed image is prevented and a clean image can be printed.

Abstract: An ink for a liquid electrophotographic color printing system is optimized to reduce the lowering of image density due to wash-off, to obtain a stable over-toned color, and to have a wide reproducible color gamut. The ink includes a plurality of toners for yellow (Y), magenta (M) and cyan (C), each toner being provided in a respective one of a plurality of developing devices, and each toner having a pigment (p) for forming an image having a predetermined color, a binder (b) for binding the pigment on printing paper, a charge controller for imparting electrical properties on the toners, and a stabilizer. A carrier transfers the toners from the developing devices to a photoreceptor belt during development. The blending ratio (b/p) of the binder (b) to the pigment (p) of each toner for yellow (Y), magenta (M) and cyan (C) satisfies the following expressions: b/pyellow(Y)=5±1; b/pmagenta(M)=7±1; and b/pcyan(C)=8±1.

Abstract: A development apparatus of a liquid electrophotographic printer includes a photoreceptor web having an image area where an electrostatic latent image is formed and a non-image area at both sides of the image area. A development roller is installed to correspond to the image area to which a development electrical potential of a predetermined level is applied, in which developer is supplied to the electrostatic latent image. A squeegee roller removes developer remaining on the photoreceptor web, and an air injection nozzle is installed adjacent to both ends of the development roller. The air injection nozzle injects air to move developer remaining on the photoreceptor web from the non-image area to the image area so that a boundary line between the image area and the non-image area is prevented from being developed due to a difference in electrical potential therebetween.
