By using this product, a wider linear range can be obtained, which is beneficial for the target base Due to more accurate quantification, good repeatability, and high reliability.ROX dye is used to correct the fluorescence signal error generated between wells in quantitative PCR instruments, and is generally used for ABIReal Time PCR amplification equipment from companies such as Stratagene. The excitation optical systems of different instruments vary, thereforeThe concentration of ROX dye must be matched with the corresponding fluorescence quantitative PCR instrument.matters needing attention：1. Before using the reagents in this reagent kit, please gently mix them upside down to avoid foaming as much as possible, and use them after brief centrifugation. 2. This product uses RNA as a template for one-step RT-PCR experiments, and RNase contamination should be avoided during the operation process,2.It is recommended to perform RNA operations in a dedicated area, using specialized instruments and consumables. Operators should wear masks and disposable gloves and frequently change gloves. Experimental consumables should be treated with a 0.1% DEPC (diethyl pyrocarbonate) aqueous solution at 37 ℃ for 12 hours and sterilized under high pressure for 30 minutes before use.3. Each reagent in this kit should avoid repeated freezing and thawing as much as possible, as repeated freezing and thawing may lead to a decrease in product performance.4. This reagent kit must use specific primers, and the selection of primers can be based on specific experiments. The quality of primer design directly affects the results of RT qPCR reaction. When designing primers, GC content, primer length, and primer should be considered Due to factors such as location, secondary structure of PCR products, it is recommended to use professional primer design software for design.5. It is recommended to use specific probes in this reagent kit and use professional design software for design. Usage: The following examples are typical reaction systems and conditions. In practical operation, corresponding improvements and optimizations should be made based on the differences in template, primer structure, and target fragment size. (Please prepare the reaction solution on ice)1. Dissolve the RNA template, primers, 2xGoldStar Probe One Step Buffer, GoldStar Probe One Step EnzymeMix, and RNase Free Water and place them on ice for later use.2.

Please refer to the instrument manual or the specific usage requirements of each fluorescent probe for concentration adjustment during actual use.3) The amount of RNA templates is usually based on 10 pg-100 ng as a reference. Due to the different copy numbers of target genes contained in templates of different species, gradient dilution can be applied to the templates to determine the optimal template usage.4) The excitation optical systems of different instruments vary, and depending on the instrument used for fluorescence quantification, 50 x Low ROX or 50 x High ROX can be added.3. Mix well, centrifuge briefly, and collect the solution to the bottom of the tube.4.

If good experimental results cannot be obtained due to the use of primers with lower Tm values, a three-step PCR amplification can be attempted. The annealing temperature should be set within the range of 56 ℃ -64 ℃ as a reference...

Under the catalysis of alkaline phosphatase, BCIP will be hydrolyzed to produce a highly reactive product, which reacts with NBT to form an insoluble dark blue to blue-violet compound. This kit can be used for the enzymatic color development of IHC and Western Blot experiments of the AP system. Under AP catalysis, a dark blue precipitate is produced where AP conjugates are combined on tissue sections or blotting membranes. The location and expression of the target protein can be determined based on the color reaction.Product Components40×BCIP: 1 ml40×NBT: 1 mlBCIP/NBT Buffer: 40 mlPrecautions1. The working fluid should be prepared for immediate use, and the prepared working fluid will be effective within 1 hour.2. The amount of working fluid must be sufficient to ensure complete coverage of the tissue sheet or blotting membrane. To3. In order to obtain the best experimental results, be sure to optimize the experimental conditions.4. NBT is poisonous, please take necessary protective measures when using it.5. This product is only used for scientific research, not for human experiments or human treatment.Instructions1. BCIP/NBT color developing working solution preparation:According to the required amount, mix 40×BCIP, 40×NBT and BCIP/NBT Buffer in a volume ratio of 1:1:38 to form the BCIP/NBT color developing working solution.2. Color rendering:1) Blotting membrane color development: Drop the prepared working solution on the blotting membrane (or pour the blotting membrane into the BCIP/NBT color developing working solution), and incubate for 3-10 minutes at room temperature and dark. After the color development is completed, the film is immersed in water to terminate the reaction.2) Color development of tissue sections or cell slides: Drop an appropriate amount of BCIP/NBT color developing working solution on the tissue sections or cell slides that need color development, and incubate at room temperature for 3-10 minutes in the dark. Observe under the microscope to control the color development time. When the best color development effect is reached, rinse with tap water to stop the color development. After color development, the slices are counter-stained, dehydrated and transparent, and can be stored for a long time after mounting...
