Luciferase Assay Protocols

In this protocol, cells transfected with a luciferase reporter plasmid are lysed in a detergent-containing buffer. Luciferase in the extract catalyzes an oxidation reaction in which D-luciferin is converted to oxyluciferin, with production of light at 556 nm that can be quantified in a luminometer. - [Read Assay for Luciferase in Extracts of Mammalian Cells Protocol]

It is possible that some cell lines have lost the ability to perform RNAi or that cells derived from certain tissues do not support RNAi. This reporter assay, for RNAi in mammalian cells, can be used to establish whether the cells under study are susceptible to RNAi. - [Read Cotransfection of Luciferase Reporter Plasmids with siRNA Duplexes Protocol]

Protocol describes a split luciferase complementation assay used to study the interaction of proteins in cells. In the split protein strategy, a single reporter protein/enzyme (firefly luciferase [Fluc]) is cleaved into amino-terminal and carboxy-terminal halves; each half is fused to one of two interacting proteins, X & Y. Physical interactions between the two proteins reconstitute the functional reporter protein, leading to enzymatic activities that can be measured by in vitro or in vivo assay - [Read Split Luciferase Complementation Assay for Studying Interaction of Proteins X and Y in Cells]

Protocol describes a split luciferase complementation assay that can be used to repetitively and noninvasively study the interaction of proteins in small living animals. After the expression of the appropriate vectors has been checked in cell culture in vivo, studies can be performed either by implanting transiently transfected cells for short-term analysis (maximum of 7 days), or with tumor models grown from tumor cells stably expressing the complete reporter system. - [Read Split Luciferase Complementation Assay for Studying Interaction of Proteins X and Y in Living Mice]

Transfection of primary leukocytes has traditionally been a challenging but much desired protocol. It allows not only the analysis of cells in a more natural state to a cell line system, it enables the direct comparison of, for e.g. transcriptional activity using luciferase reporters, in immune cells taken from genetically-altered mice. In addition, importantly it allows for "rescue experiments" in knockout cells & the ability to over-express or reconstitute wild-type and/or mutated constructs. - [Read Transfection of Bone Marrow-Derived Mast Cells for Transcription Factor Luciferase Reporter Assays]

Transient transfection into mammalian cells is a convenient way to over express and obtain protein expression. Protocol includes: Culture conditions; Transfection of experimental cells; Preparation of Mammalian Cell Lysate for Luciferase assay. - [Read Transient Transfection and Luciferase Assay Protocol]
