(57) [Summary] (Modified) [Problem] Proteins in plasma preparations such as albumin preparations, blood coagulation factor preparations, immunoglobulin preparations for clinical, clinical diagnosis, and medical devices; enzymes and antibodies for clinical diagnosis Or a labeled antibody (or labeled antigen); a protein stabilization method capable of stabilizing an enzyme for washing a contact lens or the like irrespective of storage conditions such as solution, freezing, and lyophilization; and a composition using this method. I will provide a. A method for stabilizing a protein coexist and polymer and protein having a phosphorylcholine group of the formula 1 in a same system, as well as by polymerizing phosphorylcholine group-containing monomer polymer 1.0 × 10 -4 ~ 80% by weight, and plasma preparation protein, labeled immunologically active substance or enzyme 1.0 × 10 A stabilized composition comprising from -14 to 20% by weight and a buffer from 0 to 99.9% by weight. |
