Figure 1
Mass-spectrometric profiles of FcγRIII (calculated molecular weight 20 996 Da) reacted with (a) HgCl2, (b) K2PtCl4, (c) TMLA, (d) lead acetate or (e) KAu(CN)2. The molecular weight of the residual native peak is labeled in each panel. The number of heavy atoms covalently attached to the protein is indicated above the adduct peaks (taken from Sun & Hammer, 2000). |
