Figure 3. Cross-Laboratory CIU Fingerprints and Feature CCS Reproducibility.

Figure 3

(A) ubiquitin +6, (B) myoglobin +8, and (C) streptavidin +11. Significant spectral features identified by CIUSuite2 (F1, F2, etc.) are annotated in the VU fingerprints. Interlaboratory reproducibility of feature CCS measurements for each protein are summarized, delineated into distinct spectral features (F1, F2, etc.). (D-F) The interlaboratory standard deviations are indicated with the light blue boxes, and previous literature values (DTCCSN2), when available, are indicated with red arrows. The interlaboratory relative standard deviations (RSDs) for most (67%) CCS measurements, are within 1%. (D) Ubiquitin, (E) Myoglobin, (F) Streptavidin.
