SensoLyte® 520 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(diǎn)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®520 HCV蛋白酶檢測(cè)試劑盒提供了方便的測(cè)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™520.熒光共振能量轉(zhuǎn)移（FRET）肽。這個(gè)肽序列是來自裂解位點(diǎn)NS4A / NS4B。在這個(gè)肽中，5-FAM熒光淬滅由QXL™520完成。在分裂成兩個(gè)獨(dú)立的片段的HCV NS3/4A蛋白酶（方案1），在熒光5-FAM回收，可在激發(fā)/發(fā)射= 490 nm / 520nm被監(jiān)測(cè)。具有優(yōu)異的熒光量子產(chǎn)率和更長(zhǎng)的波長(zhǎng)，5-FAM信號(hào)不受細(xì)胞成分和測(cè)試化合物的熒光。測(cè)定檢測(cè)到低至1.56毫微克/毫升活躍的HCV NS3/4A蛋白酶。

SensoLyte® 520 HCV 蛋白酶熒光檢測(cè)試劑盒的英文描述
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.
