^aCells previously grown in medium supplemented with the appropriate fatty acid were incubated in MES buffer with 1% (wt/vol) glucose and exposed to 100 μM Sr(NO₃)₂. 

^bThe Sr²⁺ accumulation rate is given in pmoles (10⁶ cells)⁻¹ minute⁻¹, determined during the linear accumulation phase (see text). Values are means ± standard errors of the means, based on three determinations. Typical results from one of at least two independent experiments are shown. 

^cResult that is significantly different (P < 5.0%) from the control rate (0.54 ± 0.02). 

^dND, not determined.
