1. Process for immobilizing a protein containing substance onto a solid phase comprising:
- (i) forming a water soluble aggregate of a polymer containing more than one molecule of a particular protein;
(ii) contacting a liquid containing said aggregate in dissolved form with a hydrophilic solid phase so as to adsorptively, and non-covalently bind said aggregate to said hydrophilic solid phase; and
(iii) drying said solid phase to form a solid phase having said aggregate immobilized and non-covalently bound thereon.

Abstract
The present invention provides a process for immobilizing a protein or protein containing substance. The material to be immobilized is aggregated, contacted in a liquid with a hydrophilic solid phase and the solid phase, after contact has taken place, is dried. The present invention is also concerned with the solid phase prepared by this process and with the use thereof for analytical determination.

- 4. Solid phase having protein bound thereto comprising a hydrophilic solid phase having non-covalently bound thereto a protein aggregate, wherein said aggregate is formed by aggregating more than one molecule of a particular protein to form a polymer containing aggregate prior to contacting said aggregate with said solid phase, wherein said solid phase is dried following contact of said solid phase with said polymer containing aggregate.

7. Process for immobilizing a protein containing substance onto a solid phase comprising:
-
(i) forming a water soluble protein homopolymer aggregate; (ii) contacting a liquid containing said protein homopolymer aggregate in dissolved form with a hydrophilic solid phase so as to adsorptively, and non-covalently bind said protein homopolymer aggregate to said hydrophilic solid phase; and (iii) drying said solid phase to form a solid phase having said protein homopolymer aggregate immobilized and non-covalently bound thereon.

8. Solid phase having protein bound thereto comprising a hydrophilic solid phase having non-covalently bound thereto a protein homopolymer aggregate, wherein said homopolymer aggregate is formed prior to contacting said homopolymer aggregate to said solid phase, wherein said solid phase is dried following contact of said solid phase with said homopolymer aggregate.

9. Solid phase having protein bound thereto comprising a hydrophilic solid phase having non-covalently bound thereto a protein aggregate, wherein said aggregate is formed by mixing more than one molecule of a particular protein with a polyfunctional linker to form a protein containing aggregate prior to contacting said protein aggregate with said hydrophilic solid phase, wherein said solid phase is dried following contact of said solid phase with said protein aggregate.
