Per cent of albumin 



Fig. 1. Conductivities of pure albumin solutions. The abscissae represent 

 varying concentrations of albumin in per cent, and the ordinates represent specific 

 conductivities X 10~*. The increase in conductivity with increasing concentra- 

 tion of albumin is shown; the increase is greatest at pH 3.1, and least near the 

 isoelectric point (5.3). At pH 3.1, the conductivity increases from 9.2 in 1.6 per 

 cent albumin to 27.5 in 8 per cent albumin. At pH 5.3 the conductivity increases 

 from 0.9 to 4.2 with increase in albumin from 1.1 to 8.3 per cent. At pll 7.3 it 

 increases from 2.1 to 7.8 with an increase in albumin from 1.4 to 6.4 per cent.
