Abstract

Pure honeybee venom samples were submitted to two-dimensional gel electrophoresis. A total of 49 excised spots were analyzed by mass spectrometry; 39 of them resulted in the identification of 6 different known bee venom proteins and of 3 proteins that have not been described in such samples before. The first new venom protein has a platelet-derived and vascular endothelial growth factor family domain, the second protein shows no homologies with any known protein and the third matches a hypothetical protein similar to major royal jelly protein 8.
