A total of 25 spots resulting from a 2-D electrophoretic separation of C. oncophora adult ES products and three fractions (high, medium and low molecular weight classes) from a 1-D separation of ES products were subjected to MALDI-TOF-MS. A total of 12 unique proteins were identified. A further glycan-focused analysis facilitated identification of N-glycan moieties associated with the high, medium and low molecular weight fractions.
