荧光素酶
Luciferase firefly
BR
别名: 荧光素酶(萤火虫) , 重组型酵素 , Luciferase from Photinus pyralis (firefly)
产地 中国/美国/德国
所在目录 酶类
CAS号 61970-00-1
产品性质及属性
荧光素酶级别 BR
product line BioUltra
Assay ≥98% (SDS-PAGE)
mol wt mol wt 120 kDa (two non-identical subunits, each containing four free thiol groups, one of which is necessary for activity)
Protein 10-35% E1%/280
Measuring range ≤1 femtomole ATP sensitivity, (using 0.2 μg of luciferase and suitably sensitive liquid scintillation counters or luminometers)
Foreign activity ATPase ≤5 nanomolar units/mg protein；Nucleoside diphosphokinase ≤20 nanomolar units/mg protein
活力定义 One light unit produces a biometer peak height equivalent to 0.02 μCi of 14C in PPO/POPOP cocktail. Light units measured in 50 μl assay mixture containing 5 pmol ATP and 7.5 nmol luciferin in Tris-glycine buffer, pH 7.6, at 25 °C
产品描述 Two contaminant, ATP-consuming activities are assayed for in this product, ATPase and nucleoside diphosphokinase. These impurities are found to be less than 5 nanomolar units/mg protein and less than 20 nanomolar units/mg protein, respectively.
Note: Prior to 1991, a unit of firefly luciferase activity was defined as that amount which will pro
