Comparing the tumor extract to both the Pap test fluid (Fig. 3a) and swab (Fig. 3b), the proteins with the highest number of spectra in the tumor extract were hemoglobin-alpha and myosin-9, while the proteins with the most spectra in the Pap test fluid and swab (after albumin, which was omitted from the analysis for scale) were immunoglobulins. Here, MYH9 is linked to neoplasm.
