Summary of methods 3.2 & 3.3, generating CD4+ T cell clones and cell lines. A: After primary stimulation of PBMC stain cultures with tetramer and antibody. B: Single cell sort CD4+ tetramer positive cells into a 96-well plate to generate a clone or bulk the cells into a sterile capped FACS tube and plate to generate a cell line. C: After stimulation and expansion test antigen specificity of cells with tetramer staining, as well as proliferation assays and cytokine staining (not shown).
