Antivenoms manufactured by bioCSL Limited (Australia) and Instituto Clodomiro Picado (Costa Rica) against the venom of the taipan snakes (Oxyuranus scutellatus) from Australia and Papua New Guinea (PNG), respectively, were compared using antivenomics, an analytical approach that combines proteomics with immunoaffinity chromatography. Both antivenoms recognized all venom proteins present in venom from PNG O. scutellatus, although a pattern of partial recognition was observed for some components. In the case of the Australian O. scutellatus venom, both antivenoms immunorecognized the majority of the components, but the CSL antivenom showed a stronger pattern of immunoreactivity, which was revealed by the percentage of retained proteins in the immunoaffinity column. Antivenoms interacted with taipoxin in surface plasmon resonance. These observations on antivenomics agree with previous neutralization studies.
采用抗蛇毒血清组学(一种将蛋白质组学与免疫亲和色谱相结合的分析方法),对澳大利亚生物CSL有限公司和哥斯达黎加克洛多米罗·皮卡多研究所分别生产的针对澳大利亚和巴布亚新几内亚太攀蛇(盾鳞棘背蛇)毒液的抗蛇毒血清进行了比较。两种抗蛇毒血清都能识别巴布亚新几内亚盾鳞棘背蛇毒液中存在的所有毒液蛋白,不过对某些成分观察到了部分识别模式。对于澳大利亚盾鳞棘背蛇毒液,两种抗蛇毒血清都能免疫识别大多数成分,但CSL抗蛇毒血清显示出更强的免疫反应模式,这通过免疫亲和柱中保留蛋白质的百分比得以揭示。抗蛇毒血清在表面等离子体共振中与太攀毒素相互作用。这些关于抗蛇毒血清组学的观察结果与先前的中和研究一致。
