客戶簡介:
中南民族大學位于湖北省武漢市,是中華人民共和國國家民族事務委員會直屬高校,為中國“少數(shù)民族骨干計劃”資格高校、全國深化創(chuàng)新創(chuàng)業(yè)教育改革示范高校、中國高校行星科學聯(lián)盟、湖北省“國內(nèi)一流大學建設高?!薄?/p>
實驗目的:
檢測藻細胞內(nèi)總蛋白含量和抗氧化酶活性
實驗材料和器具:
樣品:微囊藻7806 (Microcystis aeruginosa PCC 7806)
工具:小美超微量超聲波細胞破碎儀(XM-650T)
耗材:10ml離心管
實驗步驟:
1.準備小美超聲波破碎儀,配加長變幅桿
2.將探頭放入準備好的樣品中處理中
3.超聲條件設置
4.具體實驗流程:取20ml集胞藻6803藻液(OD0.6-0.8),常溫離心,棄上清。沉淀加2ml的tris-HCl(40mM, PH8.0)及20ul的PMSF(100mM),超聲處理。超聲后,4度離心,取上清轉(zhuǎn)移至新的離心管,用于蛋白定量和抗氧化酶活性檢測。
注意:
1、每次破碎樣品時盡量避免探頭貼壁,也可根據(jù)客戶自己操作調(diào)節(jié)
2、由于連續(xù)超聲破碎,會使樣品溫度升高,需要客戶冰浴處理

此款儀器為上海凈信實業(yè)發(fā)展有限公司旗下小美超聲生產(chǎn)的全新超聲波破碎儀一體機,是一種特殊的、快速的、高效率的一體機破碎系統(tǒng)。可以在較短的時間內(nèi)完成對各種樣品的研磨、粉碎、混合及細胞破壁,以保留樣品活性。
產(chǎn)品簡介:
1、藥物提取,細胞,細菌,病毒組織破碎。如細胞內(nèi)含物的萃取。
2、物質(zhì)顆粒的分散、勻質(zhì),及乳化。如納米材料的分散。
3、加速溶解,加速化學反應。如用于化學合成,此超聲設備配隔音箱支架、專用隔音箱、低溫系統(tǒng)。
4、超聲破碎是聲化學設備的一種應用,可用于植物提取,水處理、固液系分散、液體中顆粒的解團聚、促進固液反應等效果,使較大粒徑的聚集體分散為較小的顆粒。穩(wěn)定化指保證粉體顆粒在液體中保持長期的均勻分散等。
