Abstract: A signal forwarding system includes: a plurality of signal forwarding devices forming a plurality of communication routes between a slave station and a master station; and a route control device that determines a communication route, wherein the route control device includes at least: a communication route calculation unit that calculates a communication route in response to a route switching request; and a forward destination setting instruction unit that outputs forward destination setting information based on the communication route, the signal forwarding devices include at least: a forward destination setting instruction acquisition unit that acquires the forward destination setting information; a forward destination set unit that changes a forward destination based on the forward destination setting information; and a forward unit that outputs input traffic based on the forward destination, and any of the route control device and the signal forwarding devices includes: a traffic monitor unit; a non-signa

Abstract: An objective of the present invention is to provide ionic polymers that can provide for polymer-comprising substrates whose surfaces can stably and easily immobilize ligands such as sugar chains interacting with biological substances, in which the ligand portion exists stably even in water or buffer, and its detection capability does not decrease for a long period of time; and substrates comprising the polymers. The ionic polymer of this invention comprises two or more ionic functional groups (A) and two or more biointeracting groups represented by formula L-X-B-[wherein, L denotes a ligand capable of interacting with a biological substance, X denotes a spacer, and B denotes a binding group] as side chains covalently bound to a main chain polymer.

Abstract: A novel saccharide chain is built on a surface by bonding a second saccharide to the glycolipid present on the surface of a self-aggregate under mild enzyme chemical reaction conditions. 1) A fine self-aggregate comprising an O-glycoside type glycolipid having the structure represented by the formula (chemical formula 2) below (in the formula X1 represents a glycosyl group or an oligosaccharide group having two to twenty-nine monosaccharides and R is as defined above), 2) a monosaccharide or its derivative and 3) a glycotransferase or glycolytic enzyme are reacted in water.

Abstract: A sulfated saccharide represented by the following general formula (I): [A]-(6SO3-GlcNAc)-[C]—R ??(I) wherein (6SO3-GlcNAc) represents a 6-sulfated N-acetylglucosamine residue, [A] represents a hydroxyl group or a saccharide residue, [C] represents a saccharide residue and R represents a hydroxyl group or a substituted hydroxyl group is disclosed. The sulfated saccharide effectively bonds to selectin protein which is present in leukocytes and hence has anti-inflammatory activity. The sulfated saccharide is expected to be widely used in the medicinal field, etc.
