Luciferase Reporters. Protein Biology Resource Library Pierce Protein Methods; Bioluminescence assay systems are being used increasingly in biology and medical research laboratories in addition to (or as alternatives to) fluorescence and chemiluminescence detection strategies. Luciferase enzymes isolated from different animal species have inherent variability in light emission, allowing two or. Die Luciferase kann auch ähnlich wie GFP in Reporter-Assays verwendet werden. Dazu wird das untersuchte Gen mit dem Gen für die Luciferase gekoppelt. 5 Alternative Luciferasen. Die meisten bekannten Luciferasen benötigen ATP für die durchgeführte Reaktion. Die Koralle Renilla reniformis benötigt nur das Molekül Coelenterazin und Sauerstoff. Dieses als Renilla-Luciferase bekannte Enzym.

Luciferase reporter assays allow you to investigate promoter activity by measuring light output from luciferase enzyme that is expressed under the control of your promoter of interest. Luciferase genes vary in stability, light output and spectral characteristics, and reporter kits are available with different luciferases for both single- and dual-spectral analyses The luciferase reporter assay is commonly used as a tool to study gene expression at the transcriptional level. It is widely used because it is convenient, relatively inexpensive, and gives quantitative measurements instantaneously. It has broad applications across various fields of cell and molecular biology - wherever you want to measure or track expression of a cloned gene Luciferasen sind strukturell unterschiedliche Enzyme, durch deren katalytische Aktivität Luciferine mit Sauerstoff zu energiereichen, instabilen Dioxetanen oder Dioxetanonen reagieren ().Beim Zerfall dieser Substanzen kommt es zur Biolumineszenz.Unterschieden werden unter anderem Firefly-Luciferasen (aus dem Leuchtkäfer), bei denen Luciferol, ATP und Sauerstoff zu Kohlendioxid, AMP und Licht. Das Dual-Luciferase® Reporter (DLR) Assay System enthält zwei verschiedene Luciferase-Reporter-Enzyme, die in jeder Zelle gleichzeitig exprimiert werden. Die Firefly-Luciferase und die Renilla-Luciferase können zwischen ihren jeweiligen Biolumineszenzsubstraten unterscheiden und aktivieren sich nicht gegenseitig. Die Firefly-Luciferase wird vom interessierenden Promotor und die Renilla.

  1. escent reaction. As few as 10-20 moles of luciferase or less per sample may.
  2. g two reporter assays. In the DLR™ Assay, the activities of firefly (Photinus pyralis) and Renilla (Renilla reniformis or sea pansy) luciferases are measured sequentially from a single sample. The firefly luciferase reporter is measured first by adding Luciferase Assay Reagent II (LAR II) to generate.
  3. Luciferase can also be used to detect the level of cellular ATP in cell viability assays or for kinase activity assays. [16] [17] Luciferase can act as an ATP sensor protein through biotinylation . Biotinylation will immobilize luciferase on the cell-surface by binding to a streptavidin - biotin complex
  4. escent light output as a sensitive measure of biological activity. We offer a full range of luciferase assay products and tools for your research. Reporter options include NanoLuc®, firefly and Renilla luciferases, which have different protein sizes, reporter stabilities and brightness. Detect the.
  5. This animation describes the basic concept of reporter assays using luciferase, and explains how a dual-luciferase assay works

A commonly used reporter gene is the luciferase gene from the firefly Photinus pyralis. This gene encodes a 61-kDa enzyme that oxidizes D-luciferin in the presence of ATP, oxygen, and Mg(++), yielding a fluorescent product that can be quantified by measuring the released light. Including coenzyme A in the reaction enhances the sensitivity of the assay and provides a sustained light reaction. The Luciferase Reporter Gene Assay is used to quantitatively measure the expression of firefly luciferase in eukaryotic cells or bacteria transfected with a vector that encodes firefly Photinus pyralis(EC luciferase. The Luciferase Reporter Gene Assay can be used in manual or automated luminometers in a microplate or tube format, as well as in scintillation counters or photographic.

目前,正准备做荧光素酶报告基因的实验,但尚未明白其具体原理!请高手详细解释此实验如何检测启动子的活性!小弟愚笨,不胜感激!萤光素酶还可以作为报告蛋白被用于分子生物学研究中,例如,用于在转染过萤光素酶的细胞中检测特定启动子的转录情况或用于探测细胞内的ATP的水平. Firefly Luciferase Assay Kit Luciferase Assay Kit (from the firefly Photinus pyralis) is an accurate, sensitive and easy method for studying gene reporter regulation and function in transformed cell lines in culture Cignal Reporter Assays provided in the Cignal Reporter Assay Kit enable rapid, sensitive, and quantitative assessment of signal transduction pathway activation by measuring the activities of downstream transcription factors. Two reporter systems are available: dual-luciferase format and GFP format The Ready-To-Glow Secreted Luciferase Reporter Assay includes a promoterless plasmid and is designed to insert your promoter of interest upstream of the sequence-optimized Metridia secreted luciferase reporter gene. Dual secreted reporter assay—luciferase & SEAP . The Ready-To-Glow Dual Secreted Reporter Assay has two live-cell reporters that do not require cell lysis. In addition to the.

Nano-Glo® Dual-Luciferase Reporter Assay System. シングルサンプル中のホタルおよび NanoLuc® ルシフェラーゼ活性を高感度に検出. N1610, N1620, N1630, N1650, N1521, N1531, N1541, N1551. Nano-Glo® Luciferase Assay Syste Reporter assays use bioluminescent reporters whose detection is based on the enzymatic reaction with an enzyme, Luciferase, with the substrate Luciferin. This blog is an overview of the Luciferase reporter assay focusing on the 4 main types. Single, Dual, Multicolored and Real-Time Luciferase Reporter Assays Luciferase assay. A scientist produces DNA constructs coding for a hypothetical transcriptional activator and a reporter sequence and introduces these constructs into cells in culture. If the protein is able to activate transcription, the cell will produce the luciferase reporter protein. The amount of luciferase produced can be quantified. The accuracy of Firefly luciferase reporter can be improved by normalizing to a control reporter, such as Renilla luciferase reporter, in the same sample. The Dual Luciferase (Firefly-Renilla) Assay System is designed to be used for high-throughput, rapid quantitation of both Firefly and Renilla luciferases from a single sample in mammalian cell culture. The Firefly Luciferase Reagent is first. Analyze PPRE-driven luciferase activity using a Luciferase Assay System (Promega) (see Note 8). 2. After treatments, carefully remove as much the growth medium as possible from cells to be assayed (see Note 9), directly add 50 μL of 1 × Reporter Lysis Buffer per well, and then shake the plate in an incubator/shaker (Labnet VorTemp 56 EVC, Labnet International, Inc.) at 900 rpm and 37 °C for.

Ein Reportergen ist ein Gen, mit dessen Hilfe die Expression anderer Gene verfolgt werden kann.Das Reportergen wird dabei meistens nach dem zu untersuchenden Gen, unter demselben Promotor eingeführt. In manchen Fällen ist auch die Aktivität des Promotors an sich von Interesse, ohne ein Zielgen.Dabei wird ein Reporterenzym, ein fluoreszentes Reporterprotein oder ein detektierbares Antigen. Assays based on luminescence are very popular for several reasons: they have a high sensitivity (between 10 and 10,000 times higher than methods based on absorption or fluorescence, depending on the specific assay and reporter used) most cell types do not have endogenous luciferase activity; luminescence assays have a large dynamic rang The luciferase reporter gene assay has recently been adapted to test the effect of microRNAs. In this chapter, we use a previously identified miR-138 targeting site in the 3′-untranslated region (3′-UTR) of the RhoC mRNA as an example to describe a quick method for testing the interaction of microRNA and mRNA Please use one of the following formats to cite this article in your essay, paper or report: APA.
