Cytotoxic activity of tumor-specific CD8 T cells
... However, in our experiment the CD8+ T cells proliferated just with the addition of the OVAprotein, because our isolation was not 100% pure and thus a small number of contaminants, such as dendritic cells or T-helper cells, remained and were sufficient to activate CD8+ T cells. The LDH colorimetric a ...
