2D gel electrophoresis of O. coriaceus salivary gland homogenates. Numbers on the left indicate molecular weight marker positions in the gel. The + and − signs indicate the anode or cathode side of the IEF dimension, which ranged from pH 3–10. Gel bands that were identified to a protein (following tryptic digestion and mass spectrometry) are shown in the gel. In some cases, more than one band accounted for the same protein, possibly due to trailing or multiple isoforms. The bands labeled with Lip OC-X correspond to lipocalins where X is the number of the OC-X protein found in Supplemental Table S2. Similarly, 7DB is for a protein of the 7DB family.
