wherein W 1 is an aliphatic hydrocarbon group, a substituted or unsubstituted aryl group, a heteroaryl group, a tertiary amino group or a tertiary or quaternary ammonium group; -W 2 -Z is a quaternary ammonium group; X and Y are each independently a single bond or an alkylene group; and Z is a biotin group as defined herein. The derivative is useful as a labelling reagent for introducing a biotin group into a nucleic acid or a protein.

摘要:
A method of producing a polymer article having a metallized surface, which comprises dissolving a polymer and a metal salt in a common solvent, forming a polymer article containing the metal salt dispersed therein from the solution, and then treating the article with a reducing agent.
摘要:
The present invention provides: a material used for immobilization of biologically active substance, which comprises a material and a carbodiimide group-containing polymer compound supported thereon, and a method for immobilization of biologically active substance, which comprises contacting a biologically active substance reactive with carbodiimide group, with a material used for immobilization of said substance, comprising a material and a carbodiimide group-containing polymer compound supported thereon. Said material is free from the problems of the prior art, can immobilize an active substance easily, and is easy to handle.
