概述
报告基因已被细胞生物学广泛使用以研究基因表达及其它与基因表达相关的细胞学事件，如受体活性、细胞内信号传导、mRNA 加工、蛋白质折叠及蛋白-蛋白相互作用等。萤火虫荧光素酶是基因表达中最常用的报告基因之一，是一种极度灵敏、响应快速且易于使用的报告基因，所催化的化学发光反应是测量基因表达最敏感的分析工具之一。
萤火虫萤光素酶（Firefly luciferase）是一种分子量约为61 kDa的蛋白，在ATP、镁离子和氧气存在的条件下，能够催化萤光素（luciferin）氧化成oxyluciferin，在luciferin氧化的过程中会发出波长为560 nm左右的生物荧光，该萤光可通过化学发光仪进行测定。
Bio-UltraBio™ 一步法萤火虫萤光素酶检测试剂盒（冻干型）是无需洗涤或收集细胞的通过化学发光法直接测定细胞内萤火虫萤光素酶活性的高灵敏度、高信号稳定性的一步法检测试剂盒。该试剂盒是[O1375169] Bio-UltraBio™ 一步法萤火虫萤光素酶检测试剂盒（即用型）的不同包装版本，两者的检测信号强度相当，信号半衰期约2小时。[O1375169] Bio-UltraBio™ 一步法萤火虫萤光素酶检测试剂盒（即用型）的检测液为即用型液体，其优点是无需配制即可直接使用，但需要-80℃保存，如果在-20℃保存时间较长后检测效果会逐渐下降。本产品为冻干粉版本，在-20℃保存非常稳定，初次使用时需用提供的检测缓冲液溶解检测底物。
注意事项：
1、 初次使用时，需用提供的萤火虫萤光素酶检测缓冲液复溶萤火虫萤光素酶底物。
2、 复溶后的萤火虫萤光素酶底物检测液应尽量避免多次反复冻融。建议第一次复溶后适当分装，然后避光保存于-20℃或-80℃。
3、 复溶后的萤火虫萤光素酶底物检测液避免长时间暴露于室温。
4、 酶促反应对温度较为敏感，加样检测前需将细胞培养板和检测液平衡至室温。
5、 检测仪器选择：能够检测化学发光的仪器都适用本试剂盒的检测，但是针对相同的样品，不同检测器本底信号值和测量值均可能不同；且对于同一样本检测，不同仪器的数值不可横向比较。
6、 为防止孔间干扰，推荐使用不透明白色或黑色细胞培养板。
使用说明：
1. 试剂准备
将萤火虫萤光素酶检测缓冲液全部倒入萤火虫萤光素酶底物，上下颠倒瓶身数次，充分溶解底物。
【注】复溶后的萤火虫萤光素酶检测液一次实验使用不完时，建议复溶后直接在冰上分装，把多余的检测试剂冻存于-20℃或-80℃。
2. 细胞裂解
1) 贴壁细胞：不用吸除细胞培养基，直接加入与培养基等体积的检测试剂。
悬浮细胞：同贴壁细胞。
2) 推荐使用量：
器皿类型 | 96孔板 | 48孔板 | 24孔板 | 12孔板 | 6孔板 |
培养基体积 (μl/孔) | 100 | 150 | 200 | 300 | 500 |
检测试剂体积 (μl/孔) | 100 | 150 | 200 | 300 | 500 |
3)室温条件下，在微型震荡器上或静置裂解5min。
3. 加样
96孔板样品可直接进行后续检测，其他类型样品每孔吸取200μl混合液（培养基+检测试剂）到检测板。
4. 检测
启动化学发光检测仪或具备化学发光功能的多功能酶标仪，根据仪器说明书及实验需求进行参数设置，随后上机读取信号值。
Genetic reporters are used commonly in cell biology to study gene expression and other cellular events coupled to gene expression, such as receptor activity, intracellular signal transduction, mRNA processing, protein folding and protein:protein interactions. Firefly luciferase is one of the most commonly used reporter genes in gene expression. It is an extremely sensitive, fast-responding and easy-to-use reporter gene. The chemiluminescence reaction it catalyzes is one of the most sensitive analytical tools for measuring gene expression.
Firefly luciferase is a protein with a molecular weight of approximately 61 kDa. In the presence of ATP, magnesium ions and oxygen, it can catalyze the oxidation of luciferin into oxyluciferin. During the oxidation process of luciferin, bioluminescence with a wavelength of approximately 560 nm is emitted, and this fluorescence can be measured by a chemiluminescence analyzer.
Bio-UltraBio™ One-step Firefly Luciferase Reporter Gene Assay Kit (Lyophilized） is a one-step assay kit for directly measuring the intracellular firefly luciferase activity through chemiluminescence without the need for cell washing or collection. It features high sensitivity and high signal stability. This kit is a different packaging version of [O1375169] Bio-UltraBio™ One-step Firefly Luciferase Reporter Gene Assay Kit (Ready-to-use), and the detection signal intensities of the two are comparable. The signal half-life is approximately 2 hour. The detection reagent in the [O1375169] Bio-UltraBio™ One-step Firefly Luciferase Reporter Gene Assay Kit (Ready-to-use) is supplied as a ready-to-use liquid, offering the advantage of direct use without reconstitution. However, it requires storage at -80°C, and prolonged storage at -20°C may gradually reduce its detection performance.In contrast, this lyophilized powder product remains highly stable when stored at -20°C. For initial use, the firefly luciferase substrate must be reconstituted with the provided firefly luciferase detection buffer.
Precautions
1. For initial use, the firefly luciferase substrate must be reconstituted with the provided Firefly Luciferase Assay Buffer.
2. Repeated freeze-thaw cycles of the reconstituted Firefly Luciferase Substrate Detection Reagent should be minimized. It is recommended to aliquot the solution upon initial reconstitution and store it protected from light at -20°C or -80°C.
3. Avoid prolonged exposure of the reconstituted Firefly Luciferase Substrate Detection Reagent to room temperature.
4. The enzymatic reaction is temperature-sensitive. Both the cell culture plate and the detection reagent must be equilibrated to room temperature prior to assay initiation.
5. Detector Selection: Any instrument capable of measuring chemiluminescence is suitable for use with this kit. However, for identical samples, the background signal and measured values may vary between different detectors. Furthermore, readings obtained from different instruments for the same sample are not directly comparable.
6. To prevent well-to-well crosstalk, the use of opaque white or black cell culture plates is recommended.
Instruction for use
1. Reagent preparation
Completely pour the Firefly Luciferase Detection Buffer into the vial containing the Firefly Luciferase Substrate. Invert the vial several times to fully dissolve the substrate.
Note: If the reconstituted Firefly Luciferase Detection Reagent is not fully used in a single experiment, it is recommended to aliquot it on ice immediately after reconstitution. The remaining aliquots should be stored at -20°C or -80°C.
2. Cell lysis
1) Adherent cells: Do not aspirate the cell culture medium; directly add the detection reagent of the same volume as the medium.
Suspended cells: The same as adherent cells.
2) Recommended usage volume:
Culture Vessel | 96-well plate | 48-well plate | 24-well plate | 12-well plate | 6-well plate |
Culture Medium Volume (μl/well) | 100 | 150 | 200 | 300 | 500 |
Detection Reagent Volume (μl/well) | 100 | 150 | 200 | 300 | 500 |
3) Lyse the cells for 5 minutes at room temperature, either on a microplate shaker or by standing.
3. Sample Addition
Samples in 96-well plates may proceed directly to the subsequent assay. For other sample types, pipette 200 μl of the mixed solution (culture medium + detection reagent) per well into the assay plate.
4.Detection
Initiate the chemiluminescence detector or a multifunctional microplate reader equipped with chemiluminescence functionality. Set parameters according to the instrument manual and experimental requirements, then proceed to measure the signal values.
