Fig. 4. Mutant S13A-1 cells chemotax more efficiently than JH10 cells in a spatial gradient of cAMP. A histogram of chemotactic indices indicates that S13A cells attain high CIs (>0.8-1.0) more frequently than JH10 cells or WT-res cells. The number of JH10, S13A-1 and WT-res cells analyzed was 20, 28 and 29, respectively. Results similar to those for S13A-1 cells were obtained for S13A-2 and S13A-3 cells.
