Molecular mass of wild type and C91S Prdx6 determined by electron spray ionization mass spectroscopy (ESI MS)

hPrdx6, Da C91S Prdx6, Da
measured calculated Δ mass* measured calculated Δ mass*
non-Reduced 24,886.14 24,888 −2.01 24,870.15 24,872.17 −1.98
Reduced 24,888.25 24,888 0.10 24,872.20 24,872.17 0.03

Samples were measured in the absence (non-reduced) or presence (reduced) of 1 mM TCEP. Calculated value is the monoisotopic mass based on the most abundant isotope for each element.
