title: [MALDI-mass spectrometry for identification of new proteins in snake venoms].
abstract: By MALDI MS, we searched cobra venoms for new low-content polypeptides. A number of new proteins with molecular masses 7-25 kDa, characteristic of the known snake protein toxins, were identified, with the content of one of them less than 0.02%.
