Product 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.

Biotium’s Steady-Luc™ 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.

Glow-type luciferase assays like Steady-Luc™ 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 Steady-Luc™ Firefly HTS Assay Kit (Lyophilized) (catalog no. 30028L), a new packaging format that includes lyophilized assay buffer for convenient room temperature shipping and storage at -20°C.

Kit Components:

  • D-Luciferin
  • Steady-Luc Firefly Assay Buffer

Features:

  • Simple: single step homogeneous assay.
  • Glow kinetics: luminescence half life of about 3 hours.
  • Economic: save up to 45% compared to other brands.

Luciferase Assays

No. Biotium’s Renilla and Firefly Assay Kits are based on flash luminescence. Samples should be treated and read individually. Alternatively, you may purchase the Steady-Glo Firefly Assay Kit for HTS. We currently do not have a Steady-Glo for Renilla Assays.

The Passive Lysis Buffer (Renilla) is compatible with the Firefly Assay, but the Firefly Lysis Buffer is not compatible with the Renilla Assay.

Luminescence values are relative and depend on the experimental system. For example, luminometers from two different manufacturers each may have 6-log capability, but one may measure a range of 1 to 1,000,000 relative light units (RLU) while the other measures 0.01 to 10,000 RLU. Both instruments can measure a dynamic range of 6-log units, but they read out different arbitrary units.
