Fig. 2From: Comparison of intact protein and digested peptide techniques for high throughput proteotyping of ApoERepresentative chromatograms of the 4 target peptides from three patients. Patient 1 expressed the ApoE3 and ApoE4 proteins, patient 11 expressed the ApoE2 and ApoE3 proteins, and patient 16 expressed the ApoE2 and ApoE4 proteins. Note that the slight difference in retention time is due to the slight variation across the four lc channels on the multiplex systemBack to article page
