英文名稱：Luciferase firefly；Luciferase from Photinus pyralis （firefly）

其他名稱：熒光素酶（螢火蟲）；重組型酵素

CAS號：61970-00-1

級別：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

活力定義：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

產品描述：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 produce 1.0 nanomole of pyrophosphate per minute at pH 7.7, 25 °C, using a system containing 0.6 mM ATP and 0.1 mM D-luciferin. The former nanomolar unit is equivalent to approximay 1.3 x 106 light units

性狀：粉末。EC：1.13.12.7

重組型酵素用途：生化研究。
