For strong target protein signals, avoid letting the working solution remain static. Gently agitate the membrane on a shaker for 1–2 minutes to prevent local depletion of reactants, which may affect the linear detection range.Remove the membrane and drain any excess working solution. Wrap it in a transparent protective cover.X-ray Film Exposure: In a darkroom, expose the membrane to X-ray film. Exposure times may vary from seconds to minutes. Develop the film and adjust exposure time for repeat imaging if necessary.CCD Imager: The membrane can be directly imaged without a protective cover. Follow the manufacturer’s instructions for image capture.The membrane can be stripped and reprobed for multiple hybridizations.PrecautionsProtect PicoLight ECL Substrate and the working solution from strong light to avoid reduced sensitivity.Due to the high sensitivity of the solution, avoid using overly concentrated antibodies to prevent high background signals.Sodium azide (NaN₃) inhibits HRP activity. Do not use NaN₃ for storing or reusing secondary antibodies.Wear a lab coat and disposable gloves for personal safety.This product is for research use only...

Product Introduction This product is a specialized kit for one-step Real-Time RT-qPCR using the probe method (TaqMan, Molecular Beacon, etc.). When using this product for Real Time RT-qPCR reaction, reverse transcription and quantitative PCR are carried out in the same reaction system, and there is no need to add reagents or open the cap of the tube during the reaction process, which avoids contamination and improves the experimental efficiency at the same time. With high detection sensitivity, strong fluorescence signal and high signal-to-noise ratio, this product is very suitable for the detection of RNA viruses and other trace RNA. The special buffer system contained in this product can maximize the effectiveness of reverse transcriptase and DNA polymerase at the same time and improve the efficiency of the reaction. A wider linear range can be obtained with this product, more accurate quantification of the target gene, good reproducibility and high confidence.ROX dye is used to correct the fluorescence signal error generated between wells of a quantitative PCR instrument, and is generally used in Real Time PCR amplifiers from ABI, Stratagene, and other companies. The excitation optics vary from instrument to instrument, so the concentration of ROX dye must be matched to the corresponding fluorescence quantitative PCR instrument. Instruments that do not require ROX calibration (G665836) Roche LightCycler 480, Roche LightCyler 96, Bio-rad iCyler iQ, iQ5, CFX96 and others. Instruments that require High ROX calibration (G665801) ABI Prism 7000/7300/7700/7900, Eppendorf, ABI Step One/Step One Plus, and others.matters needing attention1.Before using the reagents in this kit, please mix them gently by turning them up and down to avoid foaming as much as possible, and use them after brief centrifugation.2.This product uses RNA as the template for one-step RT-PCR experiment, RNase contamination should be avoided during operation, it is recommended to operate RNA in a special area, use special instruments and consumables, the operator with a mask and disposable gloves and often change the gloves, the experiment-related consumables should be processed with 0.1% DEPC (diethyl ether pyrocarbonate) aqueous solution for 12 hours at 37℃, and autoclaved for 30 minutes before use.

In the presence of high salt, DNA binds to the surface of silica coated Magheads. After rinsing, high-purity DNA is eluted in Buffer EB or deionized water. The purified DNA has good purity (A260/280 ratio between 1.7-1.9) and high integrity (>15 kb), and can be used for downstream experiments such as second-generation sequencing, quantitative PCR, and chip detection.Self provided instruments and reagents1) Constant temperature mixer2) 2/15 ml magnetic frame3) 32 channel nucleic acid extractor4) 96 channel nucleic acid extractor5) 96 DW Plate6) 8 channel Comb7) Spin tips pack8) Anhydrous ethanolPreparation and important precautions before the experiment1.Before the first use, add anhydrous ethanol to Buffer CW1, Buffer GW1, and Buffer GW2 according to the label of the reagent bottle and mark them properly.2.Magheads are strictly prohibited from freezing or centrifugation.

Add 40 to the centrifuge tube µ L Protein K and 300 µ L Buffer WSL, then place the centrifuge tube on a constant temperature mixer at 75 ℃ and 1200 rpm, shake and crack for 45 minutes to form Lysate. Remove the centrifuge tube from the constant temperature mixer, centrifuge briefly, and take the supernatant.Attention: If there is no constant temperature mixer, vortex the centrifuge tube for 10 seconds and incubate it in a 75 ℃ water bath for 30 minutes. During this period, vortex every 10 minutes for 10 seconds.3. Suck the supernatant into a new 2.0 mL centrifuge tube and add 300 µ L Buffer MSL, 300 µ L isopropanol and 20 µ L Magheads V3.

Remove the centrifuge tube from the magnetic frame and add 900 µ L Buffer CW1 (please check if anhydrous ethanol has been added before use), vortex point shake for 1 minute or vortex shake for 5 seconds, and then place it on a constant temperature mixer at 25 ℃ and 1600 rpm to shake and mix for 2 minutes (ensure that Magheads are in a mixed state during the shaking process). Afterwards, place the centrifuge tube on a magnetic stand and let it stand for 1 minute. After Magheads are completely adsorbed on the side wall of the centrifuge tube, gently invert the magnetic stand and wash the impurities on the centrifuge tube cover to completely discard the solution (keep the centrifuge tube fixed on the magnetic stand).6.

Afterwards, place the centrifuge tube on a magnetic stand and let it stand for 1 minute. After Magheads are completely adsorbed on the side wall of the centrifuge tube, gently invert the magnetic stand and wash the impurities on the centrifuge tube cover to completely discard the solution (keep the centrifuge tube fixed on the magnetic stand).8.

After Magheads are completely adsorbed on the side wall of the centrifuge tube, gently invert the magnetic stand and wash the impurities on the centrifuge tube cover to completely discard the solution (keep the centrifuge tube fixed on the magnetic stand).9. Keep the centrifuge tube fixed on the magnetic frame, use a pipette to further remove the solution from the bottom and cover of the centrifuge tube, and then leave it at room temperature for 5-10 minutes to allow the ethanol to evaporate completely.10. Remove the centrifuge tube from the magnetic frame and add 50-200 µ L Buffer EB. Vortex oscillation causes the magnetic beads to completely suspend in the eluent and then place them on a constant temperature mixer at 56 ℃ and 1600 rpm for 10 minutes of shaking and elution, or incubate the centrifuge tube in a 56 ℃ water bath for 10 minutes, with vortex oscillation every 3 minutes for 10 seconds.11. Place the centrifuge tube on a magnetic stand and let it stand for 2 minutes. After Magheads are completely adsorbed on the side wall of the centrifuge tube, transfer the eluent to a new centrifuge tube using a pipette and store at -20 ℃ for later use.II.
