This product enables continuous Real-Time RT-PCR reactions within a single tube, simplifying operations. The enzyme system employs thermolabile UDG (Uracil-DNA Hotstart HiTaq& Super M-MuLV One Step RT-qPCR Kit (with UDG) is widely recognized for its exceptional speed and quantitative accuracy. This product enables continuous Real-Time RT-PCR reactions within a single tube, simplifying operations. The enzyme system employs thermolabile UDG (Uracil-DNA Glycosylase) in combination with dUTP-containing substrates, effectively preventing carryover contamination from previous PCR products. The thermolabile UDG is completely inactivated at 50°C, ensuring it does not interfere with the reverse transcription products of the current reaction. This kit utilizes a highly stable and efficient reverse transcriptase (Super M-MuLV Reverse Transcriptase) and a chemically modified hot-start DNA polymerase (Hotstart HiTaq DNA Polymerase). It delivers high amplification efficiency and specificity, enabling robust Real-Time One-Step RT-PCR. This significantly enhances detection sensitivity and eliminates the need for post-PCR electrophoresis, making it particularly suitable for the detection of trace amounts of RNA. Specifically designed for convenient and highly sensitive one-step RT-PCR, this kit features a unique enzyme formulation and specially optimized buffer system. These ensure efficient and accurate reverse transcription and PCR amplification without the need for reaction optimization. It generates excellent standard curves over a wide quantitative range, allowing precise quantitative detection of target genes with high reproducibility and reliability. Applications: Quantitative or qualitative detection of nucleic acids using RNA as template. Reverse transcription and amplification are completed in a single tube without tube opening.Product Component ListU1492590Component100T1000T10000TStorageU1492590AHotstart HiTaq& Super M-MuLV Mix0.2 mL2 mL20 mL-20℃U1492590BBuffer Mix0.95 mL9.5 mL95 mL-20℃ Protocol:1.

The main component of the detection reagent is a redox indicator. In the oxidized stateProduct IntroductionAlamar Blue detection reagent provides a simple, rapid, reliable and safe method for cell proliferation and cytotoxicity detection, which is suitable for high-throughput detection experiments. The main component of the detection reagent is a redox indicator. In the oxidized state, it appears purple-blue and non-fluorescent, while in the reduced state, it turns into a reduction product with pink or red fluorescence, with an absorption peak of 530-560nm and an emission peak of 590nm.In the process of cell proliferation, the ratios of NADPH/NADP, FADH/FAD, FMNH/FMN and NADH/NAD in the cell increase and are in a reducing environment. The dye taken into the cell is reduced by these metabolic intermediates and cytochromes and then released outside the cell and dissolved in the culture medium, changing the culture medium from non-fluorescent indigo blue to fluorescent pink. Finally, use an ordinary spectrophotometer or fluorophotometer for detection, and the absorbance and fluorescence intensity are proportional to the number of active cells.Instructions1. Add 10µl of detection reagent to 100µl of cell suspension, and incubate in a cell incubator for 2-6 hours. The color of the medium changes from indigo blue to pink and you can proceed to the next step.2. It is recommended to use a fluorescence microplate reader for detection, the excitation light wavelength is between 530-560 nm, the emission light wavelength is 590 nm, and the relative fluorescence unit (RFU) is recorded.3. Draw a standard curve or cell growth curve: the ordinate (Y axis) is the relative fluorescence unit (RFU); the abscissa (X axis) is the cell number or time point or drug concentration.Precautions1. The appropriate density of cells can increase the detection sensitivity. For 96-well plates, we recommend seeding 100 microliters of cells per well. The cell concentration range is: 100-10,000/well for adherent cells, 2,000-50,000/well for suspension cells, and medium as a blank control. For 384-well plates, the cell concentration and seeding volume are both halved.2. The whole process should be aseptic operation, because microbial contaminants can also reduce the detection reagents and affect the experimental results.3. Pay attention to the concentration of inoculated cells and the incubation time after adding detection reagents. If the cell concentration is too high or the incubation time is too long, it will cause a secondary reduction reaction, resulting in colorlessness and disappearance of fluorescence.4. When incubating, avoid light.5. This product can use fluorescence or spectrophotometric detection, but the sensitivity of fluorescence is high, and the experimental error is small. Fluorescence detection is recommended...

Due to the high sensitivity of eukaryotic cells to endotoxins, the presence of endotoxins in plasmids can greatly reduce the transfection efficiency of eukaryotic cells. This reagent kit provides a simple, fast, and efficient new method for extracting endotoxin free plasmids. The extracted plasmids can remove endotoxins to the maximum extent possible and effectively remove contamination of genomic DNA, RNA, proteins, and other substances. This reagent kit is suitable for extracting 5-15mL of bacterial solution. On the basis of alkaline lysis of cells, it efficiently and specifically binds plasmid DNA through a new silicon-based membrane. Each adsorption column can adsorb up to 100 µ The plasmid DNA of g is effectively removed using a special buffer system and endotoxin removal filter column, effectively removing impurities such as endotoxins and proteins. The plasmid obtained from this kit has high purity and stable quality, making it particularly suitable for cell transfection. It can also be used for downstream experiments such as DNA sequencing, PCR, PCR based mutations, in vitro transcription, transformed bacteria, and endonuclease digestion.Self prepared reagents: anhydrous ethanol, isopropanol.Preparation and important precautions before the experiment:1. All components can be stably stored in a dry, room temperature (15-30 ℃) environment for 1 year, and can be stored at 2-8 ℃ for longer periods of time. Buffer P1 with RNase A added can be stably stored at 2-8 ℃ for 6 months.2. Before the first use, add all RNase A solution to Buffer P1, mix well, and store at 2-8 ℃. Before use, let it sit at room temperature for a period of time. After returning to room temperature, use.3.Before the first use, anhydrous ethanol should be added to the Buffer PW according to the instructions on the reagent bottle label.4. Before use, please check if there is any crystallization or precipitation in Buffer P2 and Buffer E3. If there is any crystallization or precipitation, you can take a water bath at 37 ℃ for a few minutes to restore clarity.5. Be careful not to come into direct contact with Buffer P2 and Buffer E3, and immediately cover them tightly after use.6.The amount and purity of plasmid extraction are related to factors such as bacterial culture concentration, strain type, plasmid size, and plasmid copy number.Operation steps:1. Take 5-15 mL of overnight cultured bacterial solution and add it to a centrifuge tube (self provided). Centrifuge at 13000 rpm (~16200 × g) for 1 minute to collect bacteria, and try to discard all the supernatant as much as possible.2.
