For the purpose of preventing the adsorption of a protein or peptide onto a molded resin article, an aqueous solution of a nonionic surfactant is contacted with the molded resin article, and subsequently the molded resin article is irradiated with a radioactive ray. The concentration of the surfactant in the aqueous solution is set to a value 0.05 to 500-fold greater than the critical micelle concentration of the surfactant at 25~C.
Dans le but d'éviter l'adsorption d'une protéine ou d'un peptide sur un article en résine moulée, une solution aqueuse d'un tensioactif non ionique est mise en contact avec ledit article en résine moulée, et ensuite l'article en résine moulée est irradié avec un rayon radioactif. La concentration du tensioactif dans la solution aqueuse est fixée à une valeur 0,05 à 500 fois supérieure à la concentration critique de micelles du tensioactif à 25 ~C.
