病毒采樣器 TIPS800
目前,隨著生物科技的發展,病毒的種類也在不斷更新,一系列新型病毒通過空氣等媒介快速傳播,可引起人類及動物的多種嚴重疾病。
由于病毒是一類不具細胞結構,具有遺傳、復制等生命特征的微生物,其大小小于細菌,故空氣中的病毒采集難度大于細菌,采集過程中的截留率也值得關注。
帝博思提供一種適用于截留病毒的產品(TIPS800),為檢測環境中的病毒提供多種解決方案。
水溶膜是一種采用明膠制成的濾膜,可溶于水。標稱孔徑3μm,區別于普通的3μm濾膜,水溶膜厚度為250μm,是普通纖維素類濾膜的兩倍以上,電鏡下可見疏松多孔結構,屬于深層過濾,可以有效截留粒徑較小的微生物。經檢測,對T3病毒具有99.94%的截留率。
電子顯微鏡下的水溶膜照片
使用便攜式病毒采樣器 TIPS800,搭配單層無菌包裝水溶膜采樣頭,通過設置合適的流速與采樣體積,對空氣中的病毒進行截留。采樣結束后使用緩沖液溶解水溶膜,收集樣品中的病毒,并進行下一步處理。
您是否也有這樣的煩惱?
● 難以尋找到合適的病毒采集方法
● 截留病毒后處理步驟復雜
● 對設備的病毒截留率表示懷疑
● 尋求輕便易攜帶的裝置進行采樣
