Due to a publisher error, two figures were displayed incorrectly. The correct figures are shown below:

SELDI profile of patient R9 serum, using a laser intensity of 250. Proteins identified by in-gel tryptic digestion and peptide mapping are labelled and fit accurately to the expected average masses as given in Table 1. The RCC-related protein at m/z=10 835.3 Da remains unidentified. The peak corresponding to SAA-1 des-R occurs at m/z=11 526.5.
N-terminal sequences of SAA-1 and SAA-2 from 2-D electrophoresis as determined by in-gel tryptic digestion and measurement by MALDI Re-TOF mass spectrometry. All fragments terminated at arginine 15, the expected tryptic cleavage site. Of note are the two peptides spanning positions 3-15 (spots 1 and 3) and 5-15 (spots 1, 2 and 3), which correspond to uncommon N-terminal post-translationally modified variants of SAA-1 visualized simultaneously by SELDI (Figure 3). Expected masses are given of the full-length protein variant.
