Abstract: Disclosed is a colorimetric sensor comprising polydiacetylene membrane liposomes, a polydiacetylene membrane film or fine particles coated with a polydiacetylene membrane, in which the polydiacetylene membrane is incorporated with a protein having a reduced molecular weight low enough not to cause color change in the polydiacetylene membrane. The examples of the reduced-molecular-weight proteins include an antibody Fab′ fragment, an antigenic protein of molecular weight of 100,000 or less, and a peptide consisting of 3-20 amino acid residue, which undergo an antigen-antibody reaction with an antigen or antibody contained in a sample. As the reduced-molecular-weight protein is also employed a combination of single-stranded DNA of 100 bases or less which hybridizes with single-stranded DNA contained in a sample to form a double-stranded DNA, and an antibody which reacts with said double-stranded DNA but does not react with the single-stranded DNA contained in the sample.

Abstract: A hemostatic agent, an age for promoting cellular adhesion and an agent for curing an injury, each comprising an alkali or alkali earth metal salt of carboxylmethyl cellulose, and a pharmaceutically acceptable carrier are disclosed.

Abstract: A tissue sealant comprising thrombin, fibrinogen, and carboxylmethyl cellulose or an alkali metal or alkali earth metal salt thereof is disclosed. The tissue sealant of the present invention promotes a hemostasis of an injury to a skin surface or a viscus, a healing of an injury, an endothelium formation of a blood vessel, an adhesive activity of animal cells, such as endothelial cells or fibroblasts in vitro, and an adhesion and agglutination of platelets.
