Figure 5. Degradation of SELENOP occurs under acidic and reducing conditions.
(A) HepG2 derived conditioned media containing 75Se-SELENOP was incubated at 37 °C for 30 min in varying concentrations of acetic acid and/or 2 mM DTT as indicated. (B) 75Se-SELENOP was purified by nickel affinity chromatography and incubated at 37 °C for 30 min.
