(A) Representative mass spectrum of the [M + 14H+]14+ TTR complex with binding of up to two T4 and Zn(II). A mass resolving power of 840 is required to separate the apo-Zn containing ions with the Orbitrap. (B) The extracted ATDs of TTR binding to one and two T4’s. (C) The extracted ATDs of TTR bound to Zn(II).
