储存条件：在-60°C或更低温度下储存

Firefly Luciferase is widely used as a reporter gene to study gene regulation and function and drug screening. Since there is no endogenous Luciferase activity in mammalian cells or tissues, it is a very sensitive genetic reporter gene. Firefly Luciferase is a 62000 Dalton protein, which is active as a monomer, and does not require subsequent processing of its activity. This enzyme catalyzes the oxidation of ATP dependent D-luciferin to oxidized luciferin, producing light emission. The firefly Luciferase follows the Michaelis Menten kinetics, so the maximum light output can be achieved only when the substrate and cofactor are in large excess. When analyzing under these conditions, the light emitted by the reaction is proportional to the number of Luciferase molecules.

Note: This is a flash type luminescence detection that requires the signal to be measured immediately after adding the working solution to the sample. It requires a single tube luminescent meter or luminescent enzyme reader with a reagent syringe. Biotium also offers the Steady Luc HTS Firefly detection kit (product number 30028L), which is a homogeneous luminescent detection with a signal half-life of 3-5 hours.

Easy to use for consistent results

The firefly Luciferase detection kit is designed to simply and effectively quantify the activity of firefly Luciferase reporter enzyme in cultured cells, with high sensitivity and linearity. This kit is a new improved substitute for the Firefly Luciferase Test Kit (Catalog No. 30003). It adopts Firefly Assay Buffer 2.0, which has better working solution stability compared to the original detection buffer.

Other commercial Luciferase tests require you to dilute all firefly substrates in the test buffer, resulting in a limited shelf life after first use. In Biotium's reagent kit, the substrate is provided as a separate stock solution, which is freshly diluted for each test to achieve excellent shelf life and provide consistent signals over time.

The measurement size is based on the 96 hole format. This kit includes sufficient cell lysis buffer to perform the specified number of measurements within the size range of 96 well to 24 well plates.

Sea kidney Luciferase has been used as a reporter gene to study gene regulation and function in vitro and in vivo. It is usually used for multiple transcriptional reporter gene detection or as a standardized transfection control for firefly Luciferase detection. Renila Luciferase is a 36000 Dalton monomer protein that catalyzes the oxidation of coelenterazine by oxygen to produce light. The activity of this enzyme does not require post translational modification and can serve as a genetic reporter gene immediately after translation. Coelenterazine also emits light through enzyme independent oxidation, a process called self luminescence. Superoxide anions and peroxynitrite in cells and tissues enhance self luminescence. This test kit uses a special buffer formula, which aims to conduct reliable linear measurement of Luciferase activity in the sea and kidney with the minimum self luminous background and excellent sensitivity.

Note: This reagent kit is a flash type luminescence detection that requires immediate measurement of luminescence after adding reagents to your sample. It requires a single tube luminescent meter or a luminescent enzyme-linked immunosorbent assay instrument with a reagent syringe.

Easy to use for consistent results

This kit is a new improved substitute for Haishen Luciferase Test Kit (Catalog No. 30004). In addition to providing a simplified experimental scheme, Renilla Luciferase Test Kit 2.0 also has Biotium Aquaphile ™  Coelenterazine, a water-soluble substrate, is different from coelenterazine's methanol solution. It can be stored at - 20 ° C with the minimum evaporation.

The measurement quantity is based on a 96 well measurement format. This kit contains sufficient passive lysis buffer to perform the specified number of measurements within the plate size range of 96 to 24 wells.

均相、高灵敏度艾美捷Firefly HTS检测试剂盒

萤火虫荧光素酶被广泛用作研究基因调控和功能以及药物筛选的报告基因。由于在哺乳动物细胞或组织中缺乏内源性活性，它是非常敏感的遗传报告基因。 然而，由反应产生的光产生导致在酶表面形成自杀性腺苷酰-氧化荧光素。 其导致具有闪光型动力学的光发射的非常短的半衰期。 因此，必须在开始反应后立即检测闪光型发光，这与样品的批量分析不相容。

Biotium的Steady-Luc™HTS检测系统是一种专有的混合物，可通过防止在酶表面形成腺苷酰氧化荧光素来改变酶促反应，从而产生持久的信号（稳定发光）。 它是一种同质的高灵敏度萤火虫荧光素酶报告基因测定试剂盒，具有约3小时的半衰期，用于定量哺乳动物细胞中的萤火虫荧光素酶表达，允许在微孔板中进行批量处理。与闪光型检测相比，发光型荧光素酶检测（如Steady-Luc™）的发光信号较低。 检测的灵敏度和极限将取决于实验系统中的荧光素酶表达水平以及光度计灵敏度。

Biotium还提供Steady-Luc™Firefly HTS检测试剂盒（冻干），冻干检测缓冲液便于室温运输和-20°C储存。

艾美捷Firefly HTS检测试剂盒#BTM-30028-1是一种均相、高灵敏度的萤火虫荧光素酶报告基因检测试剂盒。它是一种发光型检测，信号半衰期约为 3 小时，可在微孔板中进行批处理。

组件：

D-荧光素

Steady-Luc™ 萤火虫检测缓冲液

特征：

简单的单步均相测定

发光半衰期约3小时

物超所值：与其他品牌相比节省高达45%

Firefly HTS检测试剂盒属性：

化验类型/选项：高通量分析、均质分析、发光（发光型）

检测方法/读数：微孔板读取器（发光）

储存条件：在-60°C或更低温度下储存

Firefly Luciferase is widely used as a reporter gene to study gene regulation and function and drug screening. Due to the lack of endogenous activity in mammalian cells or tissues, it is a highly sensitive genetic reporter gene. However, the light generated by the reaction leads to the formation of suicidal adenosyloxyfluorescein on the surface of the enzyme. It results in a very short half-life of light emission with flashing dynamics. Because of this, flash type luminescence must be detected immediately after the reaction begins, which is incompatible with batch analysis of samples.

Steady Luc from Biotium ™  The Firefly HTS detection kit contains a proprietary mixture of substances that can prevent adenosine oxyfluorescein reactions and generate persistent luminescent signals. It generates a luminescent signal with a half-life of approximately 3 hours for high-throughput microplate detection.

Compared to flash type determination, Steady Luc ™  Isoluminescent Luciferase assay has low luminescence signal. The sensitivity and detection limit of this determination will depend on the expression level of Luciferase in your experimental system and the sensitivity of the photometer.

Live-or-Dye Fixed Viability Stains are amine reactive dyes that are impermeable to cell membranes. Dyes can enter dead cells that have damaged membrane integrity and covalently label free amines on intracellular proteins. Dye labeling is very stable and can immobilize and penetrate cells without losing fluorescence or dye transfer between cells. Live-or-Dye The staining scheme has been optimized to maximize the differentiation of live/dead cells, with minimal staining of live cells to prevent interference with immune staining.

Biotium has multiple Live or Dye options Reactive dyes are available for selection, covering the fluorescence spectrum, and achieving maximum flexibility in designing multi-color flow plates.

Biotium also offers two sampler kits, each containing five different dye colors, for excitation from all popular flow cytometry laser lines. Live-or-Dye The Sampler Kit, Standard (32016) is designed for the most common flow cytometry laser and filter configurations, where dyes can be excited by UV, Violet, Blue, Yellow Green, and Red lasers. Live-or-Dye The Sampler Kit, Spectral (32017) is designed for spectral scanning flow cytometry. It contains dyes that can be excited by ultraviolet, violet, blue, and red lasers, all of which have been demonstrated in Cytek ®  The Aurora spectral cell analyzer was validated and selected due to its ability to fill many gaps in the spectral flow panel.

Live-or-Dye Fixed Viability Stains have dead cell specificity for all cell types, including mammalian cells, bacteria, and yeast.
