Laser microdissection/mass spectrometry read-outs of 2 cases of AL and 8 cases of ALect2 amyloidosis. The proteins identified are listed according to relative abundance based on spectral counts. The first 5 proteins represent amyloid-associated proteins identified in this cohort, followed by other abundant proteins identified in the deposits. The first 2 most abundant amyloid-associated proteins (1 and 2) across the cohort and present in every amyloid type are apolipoprotein E (APOE) and serum amyloid P-component (SAP). The following 3 proteins (3-5) highlighted by red boxes represent pathogenic proteins identified in these 10 cases. Only 1 pathogenic protein is present in each case. Rows 1 and 2 represent AL, and rows 3 to 10 ALect2. See Figure 1A in the article by Mereuta et al that begins on page 1479.
