Constituents of crude snake venoms-hyalases were separated by size exclusion HPLC. Molecular masses of hyalases from snake venoms, determined by on-line capillary HPLC-mass spectrometry with electrospray ionization, were: Naja melanoleuca (black cobra) 49377Da, Naja Kaothia(Thai cobra)60265Da, Sepedon hemachatus (ringhals cobra) 49722Da. Mass determinations were repeatable within 0.03%.展开更多

In this review, we mainly reports the effects of snake venom active components, such as disintegrins and lectins in paralyzing cancer cells, blocking on cell migration, interaction with integrins, inhibition of tumor dissemination and angiogenesis. The advanced researches on the snake venom’s apoptosis-inducing components on tumors are also introduced. [展开更多
