in the present study we used the ph sensitive absorbance of 5 ( and6 ) -carboxy-4',5'-dimethylfluorescein to investigate intracellular ph ( phi ) regulation in a10 vascular smooth muscle cells : ( 1 ) the steady state phi in a10 cells averaged 7.01 +/- 0.1 ( mean +/- sem , n = 26 ) at an extracellular ph of 7.4 ( 28 mm hco3/5 % co2 ) .
