同時に、同じプロトコルに従って培地M2中でリンパ球を増殖させた。顕著なリンパ球の増殖は検出されなかった。
標準的な検査では、細胞培養培地間で何らの相違も明らかにならなかった。比濁法及び表1において構成成分として列挙される物質に対する抗体を使用して、培地M1及び培地M2をより詳しく分析した。
細胞培養培地の分析からの結果によれば、モニターされた異なる職業的ドナーに由来する血漿試料を得て、エストラジオール、コルチゾール、インスリン、及びIGF−1の濃度について分析した。結果を表2に提示する。
本発明の方法によれば、血漿試料P1〜P4を選択しない。血漿試料P5をリンパ球の培養に選択する。
血漿選択を確認するため、その後、血漿試料P1〜P5を細胞培養のために調製した。NY−ESO−1で感作された健康なドナーの末梢血から得られたリンパ球を上に記載されるプロトコルに従って培養した。P5に由来する細胞培養培地での増殖は、培地M1での増殖に匹敵した(実施例1を参照されたい。)
