Figure 6. Evidence for two different tetramers of rat PAH.

Figure 6

(a) PS-purified rat PAH is shown on native and native Western PAGE. (b) Analytical SEC (loading 100 μl at ~ 1 mg/ml) shows that there are not major changes in the tetrameric size of rat PAH in the presence or absence of Phe. (c) Analytical IEC (loading ~100 μg samples) under the same conditions as part b, reflects a significant change in the surface charge of rat PAH as a function of [Phe].
