【參數(shù)信息】
英文名稱:Vargulin (Cypridina Luciferin)
【簡單概述】
Sea fireflies were first introduced in 1966 by professors Osamu and Akemi Shimomura from the "Umi Hotaru" Japanese Ocean Found and classified in fireflies, these are benthic ostracods that can emit light and enter the water directly to cause interference and may escape from capture Food.
Cypridina luciferase (cLuc) was first discovered by Eric Thompson in 1989 S. Nagata clone, this enzyme contains 555 amino acids, has a molecular weight of 62.171kDa, and the luminescent substrate is sea fluorescein
(vargulin), which can oxidize the substrate to produce blue light (Emax=462nm).
Higher luminescence than firefly luciferase (fLuc) action substrate, and enzyme substrates do not interact with D-worm fluorescein or cavities Enterin cross-reactivity, suitable for multi-standard experiments.
This enzyme is secreted luciferase, so it is easier to detect.
海螢于1966年由Osamu和Akemi Shimomura教授從"Umi Hotaru"日本海洋螢火蟲中發(fā)現(xiàn)并歸類,這些都是底棲介形類生物能發(fā)光直射進入水中產(chǎn)生干擾而可能逃離捕食。
海螢熒光素酶(Cypridina luciferase, cLuc)于1989年被Eric Thompson和S. Nagata克隆,該酶含555氨基酸,分子量為62.171kDa,發(fā)光底物為海螢熒光素(vargulin),能將底物氧化生成藍光(Emax=462nm)。
比螢火蟲熒光素酶(fLuc)作用底物后發(fā)光亮度更高,且酶底物不會與D-蟲熒光素或腔腸素交叉反應,適合多標實驗。
【應用領域】
基因表達與細胞活性分析:作為報告基因系統(tǒng)的底物,適用于雙/多標記實驗。
便捷檢測:海螢熒光酶為分泌型蛋白,無需裂解細胞即可檢測。
生物發(fā)光進化研究:與腔腸素共屬咪唑并吡嗪酮類熒光素,但生物合成路徑不同。
其結(jié)構(gòu)類似物 水母熒光素 可用于鈣離子敏感檢測,但海螢熒光素本身在此領域的應用需進一步驗證。
