FIG. 4.
Response of rat T-cell line M6.8 to rM6 protein and human cardiac myosin. The proliferative response of line M6.8 was measured with a tritiated [3H] thymidine uptake assay. T-cell line M6.8 was cultured as 5 × 104 cells per well with 20 μg of antigen per ml. rM6, purified type 6 M protein; HCM, human cardiac myosin; Lyso, lysozyme plus 2.5 × 105 mitomycin-treated spleen cells. Samples were tested in triplicate, and the results were recorded as cpm with the background subtracted. Error bars are shown.
