Brand:HongTide(上海鴻肽生物)
Description:MCA-AVLQSGFR-Lys(Dnp)-Lys-NH2 是嚴(yán)重急性呼吸綜合征冠狀病毒主蛋白酶 (SARS-CoV Mpro) 的 FRET 底物多肽,序列中含有10個(gè)氨基酸。 MCA-AVLQSGFR-Lys(Dnp)-Lys-NH2 底物序列來(lái)源于具有 AVLQSGFRK 序列的 SARS-CoV Mpro N 末端自動(dòng)加工位點(diǎn)的殘基 P4-P5'。 MCA-AVLQSGFR-Lys(Dnp)-Lys-NH2 的 Q4 和 S5 之間的酶促裂解釋放出高熒光的 7-甲氧基香豆素 (Mca) 基團(tuán),該基團(tuán)受到 2,4-二硝基苯基 (Dnp) 內(nèi)部猝滅劑的影響,從而產(chǎn)生大量熒光強(qiáng)度增加。
MCA-AVLQSGFR Lys (Dnp) Lys NH2 is a FRET substrate peptide of the main protease of severe acute respiratory syndrome coronavirus (SARS-CoV Mpro), with a sequence containing 10 amino acids. The substrate sequence of MCA-AVLQSGFR-Lys (Dnp) - Lys-NH2 is derived from the residue P4-P5 'of SARS-CoV Mpro N-terminal automatic processing site with AVLQSGFRK sequence. The enzymatic cleavage between Q4 and S5 of MCA-AVLQSGFR-Lys (Dnp) - Lys-NH2 explains that it emits a highly fluorescent 7-neneneba methoxy Coumarin (Mca) group, which is affected by the internal quenching agent of 2,4-dinitrophenyl (Dnp), resulting in a large increase in fluorescence intensity.
