Figure 1. Solution Chemistry Does Not Affect Short-Term HY TME PrPSc Adsorption to Bentonite Clay and Silicon Dioxide Powder.

Figure 1

(A): Representative Western blots of PrPSc adsorbed to bentonite clay or silicon dioxide powder (SiO2) in DPBS, CalCl2, or NaCl solutions for 1 h, 1 d, or 7 d at 22°C. ‘Control’ indicates 250 µg eq clarified HY TME brain control (DPBS for lane 1, H2O for lanes 5 and 9). (B): Approximate PrPSc recovery in soil pellets (‘Bound’) and supernatants (‘Unbound’). Error bars represent ±1 standard error of the mean.
