Figure 2.
Human T cell clones generated from OspA-tetramer-sorted SF proliferate in response to OspA164–183. Each of the 168 T cell clones generated from SF from patient 2 was tested in a split-well assay with OspA164–183 and autologous EBV B cells as APC. After 72 h, proliferation was measured as [3H]thymidine uptake.
