    Abstract: This invention provides methods of selecting antibodies that are internalized into target cells. The methods generally involve contacting target cells with one or more members of an antibody phage display library. The members of the phage display library are also contacted with cells of a subtractive cell line. The target cells are then washed to remove the subtractive cell line cells and members of the phage display library that are non-specifically bound or weakly bound to the target cells. The target cells are cultured under conditions where members of the phage display library can be internalized if bound to an internalizing marker and internalized members of the phage display library are then identified.

    Abstract translation: 本发明提供了选择内化于靶细胞中的抗体的方法。 所述方法通常涉及使靶细胞与抗体噬菌体展示文库的一个或多个成员接触。 噬菌体展示文库的成员也与减数细胞系的细胞接触。 然后洗涤靶细胞以除去非特异性结合或弱结合到靶细胞的消减细胞系细胞和噬菌体展示文库的成员。 靶细胞在噬菌体展示文库的成员可以内化的条件下培养,如果结合到内化标记物,然后鉴定噬菌体展示文库的内化成员。
