Figure 9
The curve shown here represents a typical solubility curve for a protein and divides, as in Fig. 2, the region of undersaturation from that of supersaturation. It also illustrates the existence of the classical `salting-in' and `salting-out' regions for the protein. By taking advantage of these latter effects, supersaturation may be achieved by equilibrating a system from a point of maximum solubility (P0) to one of reduced solubility (P1 or P2) by adjusting the precipitant concentration. |
