FeaturesHigh Sensitivity – Capable of rapidly detecting proteins at femto-gram levels, outperforming other high-end products in the same category.High Cost-Effectiveness – Offers exceptional value compared to other chemiluminescence substrates of similar grade.Instructions for UseRemove the transfer membrane from the washing buffer and drain excess liquid, ensuring the membrane remains moist.Mix E-ECL Substrate and E-ECL Oxidant in equal volumes to prepare the chemiluminescence working solution (approximately 0.1 mL per square centimeter of membrane).Evenly apply the chemiluminescence working solution onto the membrane and incubate for 1–2 minutes. For highly abundant target proteins, avoid letting the working solution remain stationary. Instead, place the membrane on a shaker for 1–2 minutes to prevent localized depletion of reactants, which may affect the linear range of detection signals.Remove the membrane and drain excess working solution. Wrap the membrane in a transparent protective cover.X-ray Film Exposure: In a darkroom, expose the membrane to X-ray film. Exposure times may range from a few seconds to several minutes. Develop the film and, if necessary, adjust the exposure time for a second exposure based on the initial results.CCD Imager: The membrane can be directly imaged without a protective cover. Follow the instrument’s instructions for imaging.The membrane can be stripped and reused for multiple hybridizations.PrecautionsAvoid strong light exposure to E-ECL Substrate and the working solution, as it may reduce sensitivity.Due to the high sensitivity of the ECL solution, avoid using excessively high antibody concentrations to prevent increased background signals.Sodium azide (NaN₃) inhibits HRP activity. Avoid using NaN₃ for the storage or recycling of secondary antibodies.For safety and health reasons, wear lab coats and disposable gloves during operation.This product is intended for research use only...

The kit adopts a silica matrix membrane that can specifically bind DNA and a unique buffer system to adsorb DNA efficiently and specifically, and 0.5-3.5 µg of genomic DNA can be obtained from each swab, and the extracted DNA fragments are large, pure and of stable and reliable quality. It is suitable for enzyme digestion, PCR, library construction, Southern hybridization and other experiments.Self-contained reagent: anhydrous ethanol.Pre-experiment Preparation and Important Notes1. Anhydrous ethanol should be added to Buffer GW1 and Buffer GW2 according to the instructions on the label of the reagent bottle before first use.2. If precipitation is found in Buffer GL before use, dissolve Buffer GL in a 56°C water bath.3. All centrifugation steps can be performed at room temperature.4. Sampling: Use a buccal swab to wipe the inside of the mouth 6 times, dry for 2 hours and store. To ensure that the sample is not contaminated by food or drink, do not eat or drink for 30 minutes before sampling.Procedure1. The swab of the buccal swab was cut from the rod with scissors and placed in a 2mL centrifuge tube (supplied) and 400µL Buffer GR was added.Note: For genomic DNA without RNA contamination, add 4 µL of RNase A solution at a concentration of 100 mg/ml and shake to mix.2. Add 20 µL of Proteinase K and 400 µL of Buffer GL, immediately vortex and shake for 15 seconds and mix thoroughly.Note: Mix well immediately after adding Buffer GL; do not add Proteinase K directly to Buffer GL for use.3.56°C for 10 minutes and centrifuge briefly so that the solution on the walls of the tube collects at the bottom.4. Add 400 µL of anhydrous ethanol, vortex and shake to mix thoroughly, and centrifuge briefly so that the solution on the wall of the tube collects at the bottom of the tube.Note: The addition of anhydrous ethanol may produce a white precipitate that will not affect subsequent experiments.5. Add the solution and precipitate obtained in the previous step to the Spin Columns DS in two batches of up to 700 µL at a time into the collection tube. centrifuge the column at 12,000 rpm (∼13,400 × g) for 1 minute, pour off the waste liquid from the collection tube, and return the column to the collection tube.6. Add 500 µL of Buffer GW1 to the adsorbent column (check that anhydrous ethanol has been added before use), centrifuge at 12,000 rpm for 1 minute, pour off the waste liquid in the collection tube, and put the adsorbent column back into the collection tube.7. Add 500 µL of Buffer GW2 to the adsorption column (check that anhydrous ethanol has been added before use), centrifuge the column at 12,000 rpm for 3 minutes, pour off the waste liquid in the collection tube, and put the column back into the collection tube.Note: Step 7 can be repeated if further DNA purity is required.8. Centrifuge at 12,000 rpm for 1 minute and pour off the waste liquid in the collection tube. Leave the adsorption column at room temperature for several minutes to dry thoroughly.Note: The purpose of this step is to remove residual ethanol from the adsorption column, which can interfere with subsequent enzymatic reactions (digestion, PCR, etc.).9. Place the adsorption column in a new 1.5 mL centrifuge tube, add 50 µL of Buffer GE or sterilized water to the middle of the adsorption column overhanging the column, let stand at room temperature for 2-5 minutes, centrifuge at 12,000 rpm for 1 minute, collect the DNA solution, and store at -20℃.Attention:(1) If the downstream experiment is sensitive to pH or EDTA, it can be eluted with sterilized water. The pH value of the eluent has a great influence on the elution efficiency. If the eluent is made of water, the pH value should be 7.0-8.5 (the pH value of water can be adjusted to this range by using NaOH), and the elution efficiency is not high when the pH value is lower than 7.0.2) For long-term storage, it is recommended to elute with Buffer GE and store at -20°C...
