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...

Products IntroductionThe SuperFast Probe One Step RT-qPCR U+ Kit is designed for quantitative PCR assays using RNA as a template (e.g., RNA viruses). Using gene-specific primers (GSP), reverse transcription and qPCR reactions are completed in a single tube, eliminating the need for additional tube-opening/pipetting operations, greatly increasing throughput and reducing the risk of contamination. The dUTP/UNG anti-contamination system is introduced in this kit. The heat-sensitive UNG rapidly degrades U-containing contaminants at room temperature; it is rapidly inactivated by reverse transcription at 55°C, without affecting the efficiency and sensitivity of qRT-PCR. Combined with optimized buffer systems and antibody-modified Taq enzymes and mutated M-MLV, the SuperFast Probe One Step RT-qPCR U+ Kit provides sensitivity up to 0.1 pg of total RNA or <10 copies of RNA template and enhanced thermal stability. 5× SuperFast One Step RT-qPCR U+ Buffer contains the following components The 5× SuperFast One Step RT-qPCR U+ Buffer contains an optimized buffer system and dNTP/dUTP Mix, which is particularly suitable for high specificity, low template concentration and multiplexed rapid detection of fluorescently labeled probes such as TaqMan. caveatBefore use, please mix the product gently by turning it up and down after it is completely melted to avoid foaming, and use it after brief centrifugation. Avoid repeated freezing and thawing of the product.ROX dye is used to correct the fluorescence signal error between the quantitative PCR wells, this product does not contain ROX dye, if you need to match the ROX dye with the instrument you are using, please contact your local business or call CombiSense customer service at 4006-222-360. PCR reaction system Attention: (1) Usually, the final primer concentration of 0.2 µM can get better results, and 0.1-1.0 µM can be used as a reference for setting the range. If the amplification efficiency is not high, the concentration of primer can be increased; if non-specific reaction occurs, the concentration of primer can be decreased to optimize the reaction system.(2) The final concentration of the probe used is related to the fluorescence quantitative PCR instrument used, the type of probe, and the type of fluorescent labeling substance, please refer to the instrument manual or the specific requirements for the use of each fluorescent probe to adjust the concentration.3) Because templates from different species contain different numbers of copies of the target gene, the template can be diluted in a gradient to determine the optimal amount of template to usePCR reaction conditionsmovetemptimingcirculatereverse transcription55°C1 min1premutability95°C10s1)1denaturation95°C1 s40-45Annealing/Extension55-60°C2)10-15s3)40-45Attention: (1) The enzyme used in this product is activated under the condition of pre-denaturation at 95℃ for 30s. Under this condition, most of the templates can be well unchained. For templates with high GC content and complex secondary structure, the pre-denaturation time can be extended to 1min, so as to make the starting template fully unchained, and if the high temperature treatment time is too long, it will affect the activity of the enzyme; for simple templates, pre-denaturation time of 1-10s can also be used, and the optimal pre-denaturation time can be determined according to the template situation.(2) It is recommended to use two-step PCR reaction program, the annealing temperature should be 55-60℃ as the reference range, and the annealing temperature can be increased when non-specific reaction occurs. If you can't get good results due to the use of primers with low Tm values or long amplification products, you can try three-step PCR amplification.3) Whether the actual Real Time PCR instrument used supports rapid amplification cycles, please perform a pre-experiment to verify this for the first attempt...
