Quantitative measurement of protein expression levels using capillary electrophoresis. (A) Electropherogram of the A1AT, PYCR2, TTR, ApoA-I, VDBP and isoform-2 of MMRN1 levels in serum samples from the HPV negative normal controls (N1-N5), HPV positive normal controls (N6-N15), and patients with stage I (C1-C5), stage II (C6, C7, C10-C14 and C16), stage III (C23-C27) and stage IV (C28-C31) cervical cancer. (B) Box plots demonstrating the distribution of protein expression in serum samples from the normal and stage I–IV cervical patients. *P<0.05, **P<0.01 and ***P<0.001. A1AT, α-1-antitrypsin; PYCR2, pyrroline-5-carboxylate reductase 2; TTR, transthyretin; ApoA-I, apolipoprotein A-I; VDBP, vitamin D binding protein; MMRN1, multimerin-1.
