Biotium D-Luciferin, POTASSIUM SALT
D-Luciferin is a substrate for the enzyme firefly luciferase. Chemiluminescence at 560 nm is generated when luciferin is oxidized by an ATP-dependent process, catalyzed by luciferase. Luciferase is encoded by the luc gene, which is widely used as a reporter gene in a variety of cells. Because of the intrinsic low background of chemiluminescence technique, detection of the luc gene expression can be made at very low level. In addition, luciferin/luciferase has been used to measure 1015 molar quantity of ATP. D-luciferin, potassium salt is a water-soluble form of D-luciferin.Properties: Light yellow solid soluble in water; Store at -20°C and protect from light; C11H7KN2O3S2; MW 318.4; CAS No. [115144-35-9].

LifeSensors Ubiquitin-AMC 50µg
Ubiquitin-AMC is prepared via the conjugation of 7-amino-4-methylcoumarin (AMC) to the C-terminus of mature ubiquitin leading to quenching of the intrinsic fluorescence of AMC. Upon incubation with a protease recognizing ubiquitin, such as USP2 or UCHL3, AMC is released and an increase in fluorescence can be measured using at 460 nm (380 nm excitation). The high purity of LifeSensors’ Ubiquitin-AMC results in improved signal to background ratios. This protein contains no extraneous tags.
