This is achieved by (1) spiking a complex Internal Standard (WORKFLOW-A) into a biological sample to a) quantify all the biochemicals in the sample relative to their counterparts in the Internal Standard, b) suppression-correct each compound and c) normalize sample to sample variances; and (2) injecting the same well characterized Long-Term Reference Standard (WORKFLOW-B) to create a daily retention time (RT) library of all compounds to be found in the Internal Standard for reproducible ID, and to measure day-to-day (QA/QC) to assure reproducible instrument performance. The system is completely automated using IROA ClusterFinder™software.IROA TruQuant IQQ Workflow Kit contains the materials and tools for the analysis of 90 experimental samples. The kit is intended to be used for mass spectrometry metabolomics applications... Read More | Product content:M665754Component25 TStorageM665754ATris-HCl, 1 mM, PH 8.01 mL-20℃.

Avoid freeze/thaw cycle Product Introduction:This kit uses the method of adding a poly (A) tail at the 3 'end of miRNA to give miRNA a Poly (A) tail, followed by reverse transcription using Oligo (dT) - Universal tag universal reverse transcription primers to synthesize the first stranded cDNA corresponding to miRNA. The miRNA cDNA first strand synthesis kit contains all the reagents required for the miRNA 3 'end Poly (A) tail modification process and the reverse transcription process after modification. This kit has a very high Poly (A) modification and reverse transcription efficiency, which can range from 1 ng-2 µ The first strand of cDNA corresponding to miRNA was effectively obtained from the total RNA of g. And the operation is simple and fast, which can be used to simultaneously detect multiple miRNAs from a synthesized cDNA reaction. This not only reduces errors and saves samples, but also achieves high-throughput detection.Note: This kit must be used in conjunction with the miRNA fluorescence quantitative detection kit.Self prepared experimental materials: 1 ng-2 µ Total RNA of g, or 0.1 ng-1 µ Small molecule RNA of g.Notes:To prevent RNase pollution, attention should be paid to the following aspects:1. Use plastic products and gun heads without RNase to avoid cross contamination.2. Glassware should be dry baked at a high temperature of 180 ℃ for 4 hours before use. Plastic containers can be soaked in 0.5 M NaOH for 10 minutes, thoroughly rinsed with water, and then sterilized under high pressure.3. The solution should be prepared using water without RNase.4. Operators should wear disposable masks and gloves, and change gloves frequently during the experiment.Usage:A. The process of miRNA adding Poly (A) tail:1.based on the amount of RNA used, dilute the total RNA of 10 mM ATP with 1 mM Tris (pH 8.0) according to the following formula: ATP dilution coefficient=5000/__ ngExample: If the initial amount of total RNA is 100 ng, then the ATP dilution coefficient is 5000/100=50. About to dilute ATP 50 times (1 µ 10 mM ATP plus 49 for l µ 1 mM Tris at pH 8.0.2.

Please determine the amount added based on the abundance of the target miRNA.3. Gently mix the above reaction solution and briefly centrifuge to collect the liquid at the bottom of the tube. Incubate at 37 ℃ for 15 minutes. After this process is completed, immediately proceed with the synthesis of the first strand cDNA or temporarily store it at -20 ℃.

Avoid freeze/thaw cycle.ProductsThe Nc-Nucleus/Plasma Protein Extraction Kit is a simple and rapid method for extracting nucleus and plasma proteins from mammalian cells and tissues, and the extracted proteins remain biologically active. The kit first cleaves the cell membrane and releases plasma proteins using the plasma protein extraction reagent, and then centrifuges the nucleus to obtain a nucleus precipitate. Finally, the nuclear proteins are extracted by the nuclear protein extraction reagent. The extracted nuclear and plasma proteins are of high purity, effectively avoiding cross-contamination of nuclear and plasma proteins, and can be used for subsequent operations such as Western, Gel Shift, reporter gene detection and enzyme activity determination.Caveat1. If phosphorylated proteins are to be extracted, add a phosphatase inhibitor to the extraction reagent.2. All sample handling should be done on ice.3. The amount of reagents can be adjusted according to the specific experimental situation to ensure that the ratio of each reagent used is Nc-Buffer A:Nc-Buffer B:Nc-Buffer C = 100:5.5:50.4. Higher speeds can be used for centrifugation.ProcedureI Extraction of cytoplasmic and cytosolic proteins from cells1. Please remove the extraction reagents Nc-Buffer A and Nc-Buffer C for pre-cooling before protein extraction.2. Collect the cells and count them. Centrifuge to remove supernatant.3. 1×107 cells were added with 1 ml of Nc-Buffer A (added to Protease Inhibitor Cocktail at a ratio of 1:99 within 2-3 minutes prior to protein pumping), vortexed for 5 seconds to mix well, and incubated on ice for 20 minutes.Note: The characteristics of various cells are different, and the amount of Nc-Buffer A needs to be adjusted according to the characteristics of different cells. If the protein concentration is small, reduce the amount of Nc-Buffer A and subsequent Nc-Buffer B and Nc-Buffer C proportionally.4. Add 55 µl of Nc-Buffer B, vortex for 5 seconds to mix thoroughly, and incubate on ice for 1 minute.5. Centrifuge at 12,000 rpm (~13,400 x g) for 15 minutes at 4°C, collect the supernatant (as clean as possible) into a new centrifuge tube and store at -20°C (this extract is cytoplasmic protein).6. Add 500 µl of Nc-Buffer C (add Protease Inhibitor Cocktail at a ratio of 1:99 before use) to the precipitate obtained in the previous step, vortex for 5 seconds to mix thoroughly, resuspend the precipitate and incubate on ice for 40 minutes, vortexing and mixing at 10-minute intervals for about 15-30 seconds each time.7. Centrifuge at 12,000 rpm for 15 minutes at 4°C, collect the supernatant (as clean as possible) into a new centrifuge tube and store at -20°C (this extract is for cytosolic proteins).II Extraction of cytoplasmic and cytosolic proteins from tissues1. Sampling and preservation of tissues.2. Remove the extraction reagents Nc-Buffer A and Nc-Buffer C for pre-cooling before protein extraction.3. Weigh the tissue and add 1 ml of Nc-Buffer A per 100 mg of tissue (add Protease Inhibitor Cocktail 2-3 minutes before protein extraction at a ratio of 1:99), homogenize well on ice with a homogenizer, and incubate on ice for 20 minutes.Note: The characteristics of various tissues are different, and the amount of Nc-Buffer A needs to be adjusted according to different tissues. If the protein concentration is small, reduce the amount of Nc-Buffer A and subsequent Nc-Buffer B and Nc-Buffer C proportionally.4. Add 55 µl of Nc-Buffer B, vortex for 5 seconds to mix thoroughly, and place on ice for 1 minute of incubation.5.

It is the only kit that allows users to select and couple their choice of carboxylated particle with their chosen protein.Employing a unique mechanism to immobilise proteins, Anteo′s advantages outweigh those of conventional covalent chemistries such as NHS/EDC or passive binding. This facilitates coupling of antibodies with ease, improved functionality and reproducibility, leading to better uniformity between experiments.Anteo′s Activation Reagent is water-based and replaces the dry chemicals you would use with the traditional NHS/EDC method. Our One-Step-Activation only takes one hour, and improves efficiency in terms of both time and cost. It also provides the ability to either store activated particles up to 12 months for later use, or to immediately couple proteins.Particle-Based Immunoassays, Lateral Flow, Bioseparations and Immunoprecipitation...
