A biomaterial structure containing a larger amount of biomaterial than the conventional art with maintaining the reactivity of the biomaterial is provided by linking particulate lumps in which the biomaterial is bound with a compound capable of binding to the biomaterial, wherein the particle diameter of the particulate lumps is 10 &#x3bc;m or smaller.

Biomaterial construct, its producing method, biomaterial support, target material purifying method, affinity chromatography container, separation chip, analyzing method and analyzing separator for target material, biomaterial complex, and its support, sensor chip, solid support with biomaterial fixed thereon

An ink-jet recording liquid using a dye and a pigment, which is excellent in dispersibility and has good printing performance and storage stability, and a process for producing the same are provided. There are provided an ink-jet recording liquid containing a pigment, a dye and a surfactant which are incorporated in an aqueous medium, characterized in that (1) the pigment and the dye at least partly comprise a pigment and a dye reversibly adsorbed thereon without involving a chemical reaction, (2) the dye reversibly adsorbed on the pigment without involving a chemical reaction contains a dye having a dye adsorption shown by the following formula (1) of 0.02 g/g or more, and (3) as the surfactant, a nonionic surfactant and an anionic surfactant coexist; and a process for producing the same.
