Chemotactic analysis of lithium sensitivity.

Cells were treated with 7mM LiCl or NaCl (control treatment) for one hour prior to analysis. Values shown are the mean ± standard error of data from at least three independent experiments. Directionality is defined as the total distance moved divided by the net distance moved. Statistical analysis: two-tailed t-test.

Relative lithium sensitivity
This is based on the difference between the numerical values for lithium treatment of wild type and mutant cells, as calculated by (value of mutant in Lithium)/(value for WT in Lithium). For Directionality: (- - -) 60–69% of wild type; (- - -) 70–79% of wild type; (- -) 80–89% of wild type; (++) 110–119% of wild type; (+++) 120–129% of wild type. For speed: (- - -) 25–49% of wild type; (- -) 50–74% of wild type; (-) 75–99% of wild type; (++) 125–149% of wild type; (+++) 150–174% of wild type.
