Polyunsaturated lipids are susceptible to an oxidative attack, typically by reactive oxygen species, resulting in a well-defined chain reaction with the productionLipid peroxidation is the degradation of lipids that occurs as a result of oxidative damage and is a useful marker for oxidative stress. Polyunsaturated lipids are susceptible to an oxidative attack, typically by reactive oxygen species, resulting in a well-defined chain reaction with the production of end products such as malondialdehyde (MDA). Lipid peroxidation may contribute to the pathology of many diseases including atherosclerosis, diabetes, and Alzheimer′s.Lipid peroxidation (MDA) assay kit has been used to determine the levels of malondialdehyde (MDA).Suitability: Suitable for the measurement of malondialdehyde (MDA) in a variety of samples including tissue, cells and plasmaPrinciple: In this kit, lipid peroxidation is determined by the reaction of MDA with thiobarbituric acid (TBA) to form a colorimetric (532 nm)/fluorometric (λex= 532/λem= 553 nm) product, proportional to the MDA present...

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...
