surprisingly , this number is constant within twofold over the entire range of cellular division arrest responses to alpha-factor , that is , from a 1.9-fold inhibition of the rate of cell passage through start at 0.17 nm alpha-factor to a 125 +/- 5 h maximum arrest at saturating alpha-factor concentrations of greater than 170 nm .
