Abstract: The present invention relates to a carrier core material for electrophotographic developer, having a ferrite composition and having a supernatant transmittance of 85.0% or more, a method for producing the carrier core material, a carrier for electrophotographic developer, containing the carrier core material, and a developer containing the carrier.

Abstract: Carrier particles for forming a wiring circuit pattern by an electrophotographic developing method which are used for directly forming a circuit shape on an insulating layer, with any of a metal powder, an inorganic compound powder, or a mixed raw material powder thereof used as a toner powder for forming a circuit, the toner powder for forming a circuit being adhered to a surface of the carrier particles by electrostatic force and then transported to a surface of the insulating layer, wherein the carrier particles include a resin coated layer of an acrylic resin composition containing an amino-group-containing polymer on the surface of the carrier core material particles, the coating amount of the acrylic resin composition is 0.3 to 3.0% by weight based on a carrier core material weight of 100% by weight, and a shape factor SF-1 of the carrier core material particles is 100 to 110.

Abstract: This invention relates to novel vectors and host cells containing nucleic acids coding for a polypeptide having thrombin binding ability, anticoagulant activity and thrombolytic activity. The polypeptide can be efficiently produced in large quantities by means of genetic recombination techniques using the vectors and host cells of the present invention. Since the polypeptide exhibits anticoagulant activity and thrombolytic activity without generating side effects such as bleeding tendencies, it can be applied effectively to the prevention and treatment of hypercoagulability-related diseases.

Abstract: This invention relates to a novel polypeptide which is obtained by means of genetic recombination DNA techniques and has thrombin binding ability, anticoagulant activity and thrombolytic activity. The polypeptide of the present invention can be produced in a large quantity and efficiently by means of genetic recombination techniques. Since the polypeptide of the present invention exhibits anticoagulant activity and thrombolytic activity without generating side effects such as bleeding tendency, it can be applied effectively to the prevention and treatment of hypercoagulability-related diseases.
