SensoLyte® 490 HCV Protease Assay Kit *Fluorimetric* 產(chǎn)品介紹
丙型肝炎病毒(HCV)NS3/4A蛋白酶是病毒在NS3-NS4A,ns4a-ns4b,ns4b-ns5a,和ns5a-ns5b這些位點非結(jié)構(gòu)蛋白裂解所需的。這些裂解的病毒蛋白的成熟至關(guān)重要。因此,該蛋白酶成為開發(fā)抗HCV藥物的關(guān)鍵目標(biāo)之一。該 SensoLyte®490 HCV蛋白酶檢測試劑盒提供了方便的測定。HCV NS3/4A蛋白酶抑制劑和連續(xù)定量高通量篩選HCV NS3/4A蛋白酶活性采用5-FAM / QXL™490.熒光共振能量轉(zhuǎn)移(FRET)肽。這個肽序列是來自NS4A /細(xì)胞裂解位點的半胱氨酸。自然裂解位點與γ-氨基丁酸取代(阿布)和易斷裂的肽鍵以酯鍵。這些修改提高kcat / Km值的100倍以上,使檢測的活性的NS3/4A在納摩爾濃度的蛋白酶。在FRET肽,熒光淬滅的EDANS DABCYL。在分裂成兩個單獨的片段的HCV NS3/4A蛋白酶在阿布阿拉債券(見方案1),在熒光EDANS恢復(fù),可以監(jiān)測在340 nm的激發(fā)/發(fā)射= 490n實驗是在一個方便的96孔或384孔微孔板格式進行。

SensoLyte® 490 HCV 蛋白酶熒光檢測試劑盒的英文描述
HCV protease is identified as an important drug-screening target. The SensoLyte® 490 HCV Protease Assay Kit uses an optimized FRET peptide substrate for the continuous measurement of HCV NS3/4a activity. This FRET substrate is cleaved specifically by HCV NS3/4a protease thereby liberating the C-terminal peptide-fluorophore fragment from the proximity quenching effect of the dark quencher, resulting in a more than 10-fold increase in fluorescence. This assay can detect HCV NS3/4a protease activity at 1 pmole. The kit contains: • EDANS/DABCYL-based FRET peptide substrate (Ex/Em=340/490 nm upon cleavage) • Assay buffer • Fluorescence reference standard for calibration • A detailed protocol.
