SensoLyte® 520 HCV Protease Assay Kit *Fluorimetric* 产品介绍
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这些位点非结构蛋白裂解所需的。这些裂解的病毒蛋白的成熟至关重要。因此,该蛋白酶成为开发抗HCV药物的关键目标之一。该 SensoLyte®520 HCV蛋白酶检测试剂盒提供了方便的测定。HCV NS3/4A蛋白酶抑制剂和连续定量高通量筛选HCV NS3/4A蛋白酶活性采用5-FAM / QXL™520.荧光共振能量转移(FRET)肽。这个肽序列是来自裂解位点NS4A / NS4B。在这个肽中,5-FAM荧光淬灭由QXL™520完成。在分裂成两个独立的片段的HCV NS3/4A蛋白酶(方案1),在荧光5-FAM回收,可在激发/发射= 490 nm / 520nm被监测。具有优异的荧光量子产率和更长的波长,5-FAM信号不受细胞成分和测试化合物的荧光。测定检测到低至1.56毫微克/毫升活跃的HCV NS3/4A蛋白酶。

SensoLyte® 520 HCV 蛋白酶荧光检测试剂盒的英文描述
The SensoLyte® 520 HCV Assay Kit uses a new FRET peptide substrate that incorporates 5-FAM (fluorophore) and QXL™ 520 (quencher) for a continuous measurement of enzyme activities. In the intact FRET peptide, the fluorescence of 5-FAM is quenched by QXL™ 520. Upon cleavage of the FRET peptide by HCV NS3/4a protease, the fluorescence of 5-FAM is recovered and can be continuously monitored at excitation/emission = 490 nm/520 nm. With superior fluorescence quantum yield and longer emission wavelength, this 5-FAM/QXL™ 520-based FRET peptide shows less interference from autofluorescence of test compounds and cellular components. This assay is ten times more sensitive than an EDANS/DABCYL based assay and can detect 0.1 pmole of HCV NS3/4a protease. The assays are performed in a convenient 96-well or 384-well microplate format. The kit contains: • 5-FAM/QXL™ 520-based FRET peptide substrate (Ex/Em=490/520 nm upon cleavage) • Fluorescence reference standard for calibration • A detailed protocol.
