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.

Read More | CFDASE cell proliferation and tracking detection kit is a kit for cell proliferation and tracking detection based on CFDA se. This kit is composed of CFDASE powder, solvent and staining buffer. CFDASE is a derivative of fluorescein diacetate (FDA), which has cell membrane permeability and CFDASE cell proliferation and tracking detection kit is a kit for cell proliferation and tracking detection based on CFDA se. This kit is composed of CFDASE powder, solvent and staining buffer. CFDASE is a derivative of fluorescein diacetate (FDA), which has cell membrane permeability and does not have fluorescence luminescence. When CFDASE penetrates the cell membrane into living cells, it can be catalysed by esterases in the cytosol to produce carboxyfluorescein succinimidyl ester (CFSE), which can emit strong green fluorescence, cannot penetrate the cell membrane, and can remain intact in the cell. CFSE can also spontaneously and irreversibly covalently bind to intracellular amino groups to couple to cellular proteins. Meanwhile, the excess and uncoupled CFDASE returned to the extracellular medium by passive diffusion and was cleared by subsequent washing steps. The fluorescence of non dividing cells labeled by CFDASE is very stable, and the stable labeling time can reach several months, so it is very suitable for cell community analysis. The fluorescence of CFDASE labeled cells is very homogeneous, which is superior to other cell tracking fluorescent probes used previously, such as PKH26, and the fluorescence distribution of the divided progeny cells is also very uniform. In the process of cell division and proliferation, CFSE labeled fluorescence can be evenly distributed to the two progeny cells, and the fluorescence intensity becomes half of the parental cells. According to the fluorescence intensity, flow cytometer (FL1 channel) can detect undivided cells, cells that divide once (1 / 2 of the fluorescence intensity), twice (1 / 4 of the fluorescence intensity), three times (1 / 8 of the fluorescence intensity), and cells that divide more times. CFDASE can detect up to eight or more cleavages. CFDASE labeled cells can be used for proliferation studies in vitro and in vivo, and have the function of not staining adjacent cells. CFDASE is most commonly used to detect the proliferation of lymphocytes, and can also be used to detect the proliferation of fibroblasts, NK cells and other cells. CFDASE labeled cells showed green fluorescence. In addition to flow cytometry to detect cell proliferation, fluorescence microscopy can also be used for homogeneous staining of cell tracking observation.Components:ComponentsC598182-20TC598182-500TA. CFDA SE1 tube1 tubex5B.CFDA SE solvent20 µL500 µLC.10x CFDA SE Buffer1 mL x250 mLMatters needing attention：1. please centrifuge the product to the bottom of the tube immediately before use, and then conduct subsequent experiments. 2. CFDA and Se are easily hydrolyzed and will deteriorate quickly in aqueous solution. Please avoid contact with water during use. Contact with water during the process of labeling cells is within the permitted range. 3. CFDA se solvent will solidify at lower temperatures such as 4 º C and ice bath and stick to the bottom, wall or cover of the centrifugal tube. It can be used after incubating in a 20-25 º C water bath for a while until it is completely dissolved. 4. this kit optimizes the CFDA se staining system, but users are advised to explore the optimal working concentration and staining time according to their own cell type, culture conditions and application direction. Different cells have different lactonase activities, so the staining effect is different. 5. fluorescent dyes have quenching problems. Please avoid light during operation to slow down fluorescence quenching. 6. for your safety and health, please wear experimental clothes and disposable gloves.Usage method:1. Preparation of reagents(1) Preparation of CFDA SE storage solution: Take one tube of CFDA SE provided in the reagent kit and restore it to room temperature. Instantly centrifuge to allow the powder to fully settle to the bottom of the tube. Add 100 µ L CFDA SE solvent (add 20 µ L CFDA SE solvent) to it and dissolve it thoroughly to prepare CFDA SE storage solution (1000 ×). Prepared CFDA SE storage solution, stored at -20 ℃ in the dark, with a shelf life of two months- Storing at 70 ℃ in the dark can extend the usage time appropriately.(2) Preparation of CFDA SE Buffer: Dilute 10 x CFDA SE Buffer to 1 x with sterile cell culture grade water as needed. The prepared 1 × CFDA SE Buffer can be stored at 4 ℃ and can be stored at -20 ℃ if not in use for a long time.2. Marking and detection(1) Centrifuge the collected cells, use 1 mL 1 × CFDA SE Buffer to re suspend the cells in a 15 mL centrifuge tube, and adjust the cell concentration to 1-5 × 106 cells/mL.(2) Preparation of CFDA SE working solution: Dilute the CFDA SE storage solution (1000 ×) with 1 × CFDA SE Buffer to 2 ×.(3) Staining: Add 1 mL of CFDA SE working solution (2 x) to 1 mL of cell suspension to be labeled, invert and mix well, and incubate at 37 ℃ for 10 minutes.(4) Immediately add 5 times the volume of preheated complete culture medium (including serum) to the centrifuge tube, invert and mix well to terminate the labeling reaction.(5) Centrifuge at 1000 rpm for 5 minutes at room temperature to remove the supernatant, then wash once with 5-10 mL of complete culture medium.(6) Add 5-10 mL of complete culture medium and incubate at 37 ℃ for 5 minutes to promote the residence of CFDA SE in the cells and the entry of unreacted CFDA SE into the complete cell culture medium. Centrifuge at 1000 rpm for 5 minutes at room temperature to remove the supernatant and complete the final wash.(7) Subsequently, the cells can be cultured using the normal cultivation method. The labeling effect can be directly observed under a fluorescence microscope, or cell proliferation can be detected by flow cytometry after appropriate cultivation time, showing green fluorescence. The labeled cells can also be used for transplantation in live animals and for fluorescence tracing.Note: a If cell fixation is required, use aldehyde fixatives such as 4% paraformaldehyde to fix at room temperature for 15 minutes; If additional labeling such as antibody labeling is required afterwards, please permeabilize the cells with ice acetone for 10 minutes. b. The optimal labeling concentration and incubation time for CFDA SE vary for different cells. The initial experiment can be conducted according to the experimental steps. If the effect is not satisfactory, it is recommended to adjust the staining concentration and incubation time to achieve the best labeling effect.Scope of application：Cell proliferation assay...
