摘要:
A cushioning molded product is provided which is produced by binding a vegetable fiber with a copolymer of a saccharide and an aliphatic dicarboxylic acid to conduct molding. Further a process is provided for producing a cushioning molded product from a copolymer of a saccharide and an aliphatic dicarboxylic acid, and a vegetable fiber, the process comprising (a) mixing or adhering the copolymer and the vegetable fiber, and (b) molding the resulting mixture into an intended shape by heating the mixture to bind the vegetable fiber with the copolymer.
摘要:
To provide a measuring probe excellent in sensitivity and reproducibility, simple operation in the protein immobilization onto a support can prevent peeling or damage. A layer containing a protein is adsorbed onto a support surface to fully encircle the long axis of the support, and the adsorbed layer is treated for cross-linking with a cross-linking agent in a concentration of 1 to 5 moles to 1 mole of the protein.
