Abstract: A cross-linked polyolefin resin foam of the present invention has a total light transmittance and a thickness that satisfy a predetermined condition, and has a reflection color difference ?* of ?10 to 16, a reflection color difference ?a* of ?3 to 3, and a reflection color difference ?L* of 50 or more. According to the present invention, there can be provided a cross-linked polyolefin resin foam that can suppress a change in color tone of transmitted light while ensuring transparency, and a pressure-sensitive adhesive tape, layered product, formed product, and display member that include such a cross-linked polyolefin resin foam.

Abstract: The present invention relates to a cross-linked polyolefin resin foam obtained by cross-linking and foaming a polyolefin resin composition containing at least a polyolefin resin, wherein the cross-linked polyolefin resin foam has a total light transmittance of 45% or more at the thickness of 0.3 mm or more and less than 1.0 mm, and the cross-linked polyolefin resin foam has a total light transmittance of 30% or more at the thickness of 1.0 mm or more and 5.0 mm or less. The present invention provides a cross-linked polyolefin resin foam having excellent light transmittance.

Abstract: According to the present invention, there are provided hepatic parenchymal cell growth factor obtained by recombinant DNA technology, a gene coding for the factor, an expression vector capable of expressing the gene, a cell, in particular animal cell, transformed with the expression vector, and a process for producing the hepatic parenchymal cell growth factor.

Abstract: The present invention provides a GTP binding protein containing the following amino acid sequence, with a molecular weight of about 22K dalton and having GTP binding activity which is inhibited by N-ethyl-maleimide and GTP hydrolyzing activity:Thr-Ile-Glu-Asp-Ser-Tyr, and a method for the production of a GTP binding protein, which comprises introducing a DNA fragment containing DNA that encodes the GTP binding protein into a cloning site present at the downstream to a promoter of an expression vector, then introducing the expression vector thus constructed into a host, culturing said host, thereby expressing and accumulating the GTP binding protein and then collecting thereof.

Abstract: Provided herein are a DNA fragment which contains a base sequence coding for a non-A non-B hepatitis-specific antigenic protein occurring in cells of the liver affected with non-A non-B hepatitis, an expression vector in which said DNA fragment is inserted into a cloning site present downstream from a promoter thereof, a transformant obtained by introducing said expression vector into a host, and a process for producing said antigenic protein which comprises providing said expression vector, transforming a host with said expression vector, culturing the transforming host and collecting the protein produced therein.
