RÉCIPIENT POUR L'ADMINISTRATION, LE STOCKAGE, LA DISTRIBUTION OU LE TRANSPORT D'UNE PROTÉINE FAIBLEMENT ADSORBABLE OU D'UNE COMPOSITION CONTENANT DES PROTÉINES, ET APPAREIL POUR LA PRODUCTION D'UNE PROTÉINE OU D'UNE COMPOSITION DE PROTÉINES
There is provided a container or an equipment having low-protein adsorption properties, to be used for administering, storing, conveying or transporting protein or a composition including protein, or for producing protein or a composition including protein. A container or an equipment for producing protein or a composition including protein, wherein the surface of the container or the equipment in contact with protein or a composition including protein is formed of a fluororesin which is at least one fluororesin selected from a tetrafluoroethylene-hexafluoropropylene-based copolymer and a tetrafluoroethylene-perfluoroalkylvinyl ether-based copolymer, which has a melting point of 320°C or less and which has a total number of non-fluorinated group terminals and -CF<;sub>;2<;/sub>;H group terminals in the fluororesin of 70 or less per 1 × 10<;sup>;6<;/sup>;carbon atoms, has remarkable low-protein adsorption properties. Such a container or equipment can be used to thereby, for example, prevent, in a producing (culturing and purifying, and the like) step, a storing and delivering step and/or administration of a protein formulation such as an antibody pharmaceutical product, the protein formulation from being lost due to adsorption thereof to the equipment.
