High resolution native MS of human α-thrombin. (a) Primary sequence of human α-thrombin (UnitProt P00734, chain 328–363 and 364–622); (b) Native FT-ICR mass spectrum of human α-thrombin (10 μM in 20 mM NH4OAc), pH 6.8. The accurate mass measurement of the native human α-thrombin is shown for the 11+ precursor (inset). The annotated mass values are monoisotopic masses for the corresponding molecular species.
