ESI-MS results for gold cyanide-derivatized KIR2DL2. The KAu(CN)2-derivatization reaction was carried out using heavy atom:protein molar ratios of (a) 9:1 and (b) 28:1, respectively. The KAu(CN)2-derivatized peaks are labeled 1–5. (c) Native KIR2DL2 has a molecular weight of 22 226.0 Da (taken from Sun & Hammer, 2000). |
