User-Supplied MaterialsPBSMultichannel pipetteWhite or black opaque cell culture microplateLuminometer or microplate reader equipped with a luminescence detection module.2. Preparation Before Assay(1) Initial Reconstitution: Upon first use, transfer the entire contents of the Firefly Luciferase Reaction Buffer (Glow) bottle into the Firefly Luciferase Substrate (Glow) vial. Mix thoroughly until the substrate is completely dissolved. Aliquot the reconstituted detection reagent as needed. For long-term storage, aliquot and store at -70°C. For short-term storage, store aliquots at -20°C for no longer than one month. Use reconstituted reagent promptly.(2) Pre-assay: Before each experiment, equilibrate the aliquoted, frozen detection reagent to room temperature.3. Procedure(1) Equilibrate Plates: Remove the cell culture plate from the incubator and allow it to stand at room temperature for 5-15 minutes.Note: Use white or black opaque cell culture plates to minimize signal interference between wells.(2) Add Detection Reagent: Using a multichannel pipette, add the equilibrated Firefly Luciferase Reaction Buffer (Glow) containing the substrate to each cell culture well. The volume added should be equal to the volume of the culture medium in the well. For example:* 96-well plate: Typically add 80-100 µL culture medium; add 80-100 µL detection reagent.* 384-well plate: Typically add 20-30 µL culture medium; add 20-30 µL detection reagent.(3) Mix to Lyse Cells: To ensure complete cell lysis, place the plate on an orbital shaker or an instrument with shaking capability. Shake at medium to high speed at room temperature for 5 minutes.Note: A shaking time of 5 minutes is recommended. This can be adjusted based on cell density to ensure complete lysis and stable luminescent results.(4) Detection: Following the shaking step, immediately measure firefly luciferase reporter gene activity using a luminometer or microplate reader.Note: For optimal results, perform the detection as soon as possible after adding the detection reagent.PrecautionsInstrument Selection: Any instrument capable of detecting chemiluminescence is suitable for use with this kit. However, background signal levels and measured values for identical samples may vary between different detectors. Values obtained from different instruments for the same sample are not directly comparable. To prevent well-to-well interference, the use of opaque white or black cell culture plates is strongly recommended.Consistent Conditions: Luminescent signals can be influenced by environmental factors such as medium components and temperature. Ensure consistent detection conditions across all samples within an experiment.Temperature Sensitivity: The enzymatic reaction is temperature-sensitive. It is essential to equilibrate both the detection reagent and the cell culture plate to room temperature before adding the reagent and performing the assay.Reagent Stability: To maintain the stability of the luciferase assay reagent, aliquot it appropriately after reconstitution. For long-term storage, store aliquots at -70°C protected from light. For short-term storage, store at -20°C for no longer than one month. Use aliquots promptly and avoid repeated freeze-thaw cycles.Multiple Plate Assay: If detecting multiple cell culture plates simultaneously, strive to maintain consistent incubation time after adding the detection reagent to each plate before reading. This ensures optimal and comparable results across plates.Emission Wavelength: The bioluminescence catalyzed by firefly luciferase exhibits a peak emission wavelength of 560 nm...

The unique separation column is used for homogenization and filtration of high viscosity plant or fungal lysates, while the silicon matrix membrane is used to adsorb the RNA for purification, so that various contaminants, such as polysaccharides, are effectively removed by washing, and the eluted RNA can be directly used in various downstream experiments. The molecular weight of RNA extracted by this kit is more than 200 bases, with high purity and almost no DNA residue. For RNA experiments that are very sensitive to trace DNA, the residual DNA can be removed by digestion on a column using RNase-free DNase. The extracted RNA can be used in Northern Blot, Dot Blot, RT-PCR and in vitro translation experiments.Self-contained reagents: β-mercaptoethanol, anhydrous ethanol (freshly opened or for RNA extraction).Pre-experiment Preparation and Important Notes1. To prevent RNase contamination, attention should be paid to the following aspects:1) Use RNase-free plastics and tips to avoid cross-contamination.2) RNase-free water should be used to prepare the solution.(3) Operators wear disposable masks and gloves, and change gloves diligently during the experiment.2. To prevent RNase contamination, attention should be paid to the following aspects:1) Use RNase-free plastics and tips to avoid cross-contamination.(2) Glassware should be dry-roasted at 180°C for 4 hours before use, and plasticware can be soaked in 0.5M NaOH for 10 minutes, rinsed thoroughly with water and autoclaved.3) RNase-free water should be used to prepare the solution.(4) Operators wear disposable masks and gloves, and change gloves diligently during the experiment.3. Avoid repeated freezing and thawing of the extracted samples, otherwise it will affect the amount and quality of RNA extraction.4. Please add β-mercaptoethanol to Buffer RL before use, add 10µl of β-mercaptoethanol to 1ml of Buffer RL, it can be stored for 1 month at room temperature. Buffer RL with β-mercaptoethanol can be stored at room temperature for 1 month. β-mercaptoethanol is not required for use of Buffer RLC.5. Anhydrous ethanol should be added to Buffer RW2 before first use according to the instructions on the reagent bottle label.6. If precipitation occurs in Buffer RL and Buffer RLC, heat to dissolve and leave at room temperature.7. All centrifugation steps are carried out at room temperature and all steps are performed quickly. Procedure1. 50-100 mg of plant tissue is quickly ground to a powder in liquid nitrogen and added to 600 µl of Buffer RL (check for addition of β-mercaptoethanol before use) or Buffer RLC. vortexing and oscillating to allow for adequate lysis.Note: 1) The main component of Buffer RL is guanidine isothiocyanate, which is suitable for lysis of most plant tissues. However, in some plant tissues (e.g. endosperm of corn), due to the special secondary metabolites, guanidine isothiocyanate causes precipitation of the sample, resulting in poor RNA extraction, in this case, Buffer RLC can be added instead of Buffer RL.2) Incubation at 56°C for 1-3 minutes helps tissue lysis, but do not incubate at high temperatures for plants with high starch content.2. Transfer all the liquid obtained in step 1 to an adsorption column (Spin Columns FL) that has been loaded into a collection tube, centrifuge at 12,000 rpm (~13,400 x g) for 2 minutes, and transfer the supernatant from the collection tube to a new centrifuge tube (supplied).Note: 1) The tip of the tip of the gun can be cut off when aspirating liquids to facilitate sampling.2) Spin Columns FL removes most of the debris, but a small portion will still flow out and a precipitate will form in the collection tube after centrifugation, so be careful to avoid aspirating the precipitate when proceeding to the next step.3. Add 0.5 times the volume of anhydrous ethanol to the clean lysate obtained in step 2 and mix rapidly.Note: Precipitation may occur upon addition of ethanol, but does not affect subsequent tests.4. Transfer the solution obtained in the previous step to the Spin Columns RM in the collection tube. If it is not possible to add all of the solution to the column at one time, centrifuge the column at 12,000 rpm for 15 seconds in two batches, discard the waste solution and put the column back into the collection tube.5. Add 350 µl Buffer RW1 to the adsorbent column, centrifuge at 12,000 rpm for 1 min, discard the waste liquid and put the adsorbent column back into the collection tube.6. Preparation of DNase I mixture: Take 52µl of RNase-Free Water, add 8µl of 10×Reaction Buffer and 20µl of DNase I (1U/µl) to it, mix well, and make a final volume of 80µl of reaction solution.7. Add 80µl of DNase I mixture directly to the adsorption column and incubate at 20-30°C for 15 minutes.8. Add 350 µl of Buffer RW1 to the adsorption column, centrifuge at 12,000 rpm for 1 minute, discard the waste liquid and put the column back into the collection tube.9. Add 500 µl of Buffer RW2 to the column (check that anhydrous ethanol is added before use), centrifuge at 12,000 rpm for 15 seconds, and discard the waste solution.10. Repeat step 9.11. Place the adsorbent column back into the collection tube, centrifuge at 12,000 rpm for 1 minute, and allow the column to come to room temperature for a few minutes to thoroughly dry out the anhydrous ethanol in the adsorbent column.Note: The purpose of this step is to remove residual ethanol from the adsorption column; ethanol residue can interfere with subsequent enzymatic reactions (zymography, PCR, etc.).12. Load the adsorption column into a new centrifuge tube, add 30-50 µl of RNase-Free Water to the middle of the adsorbent membrane, leave it at room temperature for 1 minute, centrifuge at 12,000 rpm for 1 minute, and store the resulting RNA solution at -70°C to prevent degradation.Note: 1) The volume of RNase-Free Water should not be less than 30 µl, too small volume affects the recovery rate.2) If you want to increase the RNA yield, repeat step 12 with 30-50 µl of fresh RNase-Free Water.3) If the RNA concentration is to be increased, the resulting solution can be reintroduced into the adsorption column and step 12 repeated...
