Figure 3: Correlation between brain region specific peptide reference standards across all batches.

From: Global quantitative analysis of the human brain proteome in Alzheimer’s and Parkinson’s Disease

Figure 3

Two global internal standards (GIS) representing pooled peptides from all cases either from the frontal cortex or anterior cingulate gyrus were labeled with TMT channels 126 and 131. When comparing the normalized abundances from 126 and 131 reporters, the two channels showed strong linear correlation. The signals from Platform 1 (Orbitrap Fusion 1) had better correlation values than those from Platform 2 (Orbitrap Fusion 2).
