    • A method for measuring the activity of cytotoxic T lymphocytes (CTLs) includes preparing peripheral blood mononuclear cells (PBMCs) from blood of an animal; preparing mature dendritic cells by isolating monocytes from the PBMCs, differentiating the monocytes into dendritic cells for presenting an antigen molecule and pulsing dendritic cells with the antigen molecule to obtain the mature dendritic cells; preparing the CTLs as an effector cell by stimulating the PBMCs with the mature dendritic cells to activate and amplify the CTLs; preparing target cells by pulsing the PBMCs, monocytes or B cells with a cytoplasmic transduction peptide (CTP)-antigen complex generated by linking the antigen molecule of step (b) to the CTP; treating the target cells with the effector cells; and analyzing the lysis of the target cells. In addition, a kit for measuring the activity of cytotoxic T lymphocytes is provided.
    • 用于测量细胞毒性T淋巴细胞(CTL)的活性的方法包括从动物的血液制备外周血单核细胞(PBMC); 通过从PBMC分离单核细胞来制备成熟树突状细胞,将单核细胞分化成树突状细胞以呈递抗原分子并用抗原分子脉冲树突状细胞以获得成熟的树突状细胞; 通过用成熟树突状细胞刺激PBMC来激活和扩增CTL来制备CTL作为效应细胞; 通过将步骤(b)的抗原分子与CTP连接而产生的细胞质转导肽(CTP) - 抗原复合物脉冲化PBMC,单核细胞或B细胞来制备靶细胞; 用效应细胞处理靶细胞; 并分析靶细胞的裂解。 此外,还提供了用于测量细胞毒性T淋巴细胞活性的试剂盒。
