This invention provides a selective cellular fibronectin (cFN) adsorbent utilizing a nonwoven cellulose sulfate fabric and a method for fractional purification of FN which-comprises contacting an FN matter containing both plasma fibronectin (pFN) and cellular fibronectin (cFN) with the nonwoven cellulose sulfate fabric to separate pFN and cFN from each other. By the fractional purification method of the invention, cFN and pFN can be fractionated in an expedient manner and with high efficiency and both pFN and cFN can be recovered in high purity and good yield.

摘要:
Nucleotide sequences of cotton plant cDNA clones randomly selected are determined. Homology search is performed between the sequences and known gene sequences registered in the data base. Thus a gene, which controls the fiber formation mechanism in cotton plant and which can be used for industrially useful improvement, is isolated from clones having homology to a gene in the data base.
摘要:
A material is provided for immobilization of biologically active substances which are reactive with a carbodiimide group. The material contains a carbodiimide group-containing polymer supported on a carrier such as a plastic, an inorganic polymer, a metal, a natural polymer or a ceramic. The carbodiimide group-containing polymer has 2 to 100 carbodiimide groups per molecule and a molecular weight of 1,000 to 100,000, and is prepared by carbodiimidization of an organic polyisocyanate in the presence of a catalyst. The polymer may be supported as a film on part or the whole area of the carrier. Biologically active substances that may be immobilized include enzymes, hormones, antibodies, antigens, heptenes, peptides, DNAs and RNAs.
摘要:
A conductive cushion material that can effectively shield electromagnetic wave leaking from a housing of an information device such as a cellular phone and also has a cushioning function to protect electronics parts comparatively fragile to impact, as well as a method for manufacturing the same, where manufacturing processes are simple and easy, are provided. More specifically, a conductive cushion material comprising a fiber aggregate (A) composed of conductive fine wires and an elastic resin (B) containing a conductive filler (C), characterized in that at least a part of edges of the fiber aggregate (A) is exposed out of the external surface of the cushion material, while the rest of the edges are embedded in the cushion material, and that the elastic resin (B) has many cavities therein, while uniformly mixed with the conductive filler (C), and a method for manufacturing the same are provided.
