Product Overview :
Glow-type luciferase assays like HTS assay have lower luminescence signal compared to flash-type assays. The sensitivity and limit of detection of the assay will depend on luciferase expression levels in your experimental system as well as luminometer sensitivity.Biotium also offers Firefly HTS Assay Kit (Lyophilized), a new packaging format that includes lyophilized assay buffer for convenient room temperature shipping and storage at -20°C.
Size :
40 assays, 120 assays, 1,000 assays, 10,000 assays
Description :
Firefly luciferase is widely used as a reporter for studying gene regulation and function, and for pharmaceutical screening. It is a very sensitive genetic reporter due to the lack of endogenous activity in mammalian cells or tissues. However, the light production resulting from the reaction leads to formation of suicidal adenyl-oxyluciferin at the enzyme surface. It results in very short half-life of the light emission with a flash-type kinetics. Because of this, flash-type luminescence must be detected immediately after initiating the reaction, which is not compatible with batch analysis of samples.HTS assay system is a proprietary mixture of substances that modify the enzymatic reaction to produce a long lasting signal (steady glow) by preventing the formation of adenyl-oxyluciferin at the enzyme surface. It is a homogeneous high sensitivity firefly luciferase reporter gene assay kit with a half-life of about 3 hours for the quantification of firefly luciferase expression in mammalian cells, allowing batch processing in microplates.
