The ExcelRT™ One-Step RT-qPCR kit (TaqMan, no ROX) is designed for reverse transcription and quantitative real-time analysis of a specific target RNA by one-step reaction. The ExcelRT™ One-Step RT-qPCR kit (TaqMan, no ROX), consisting of One-Step RT Enzyme Mix and 2X One-Step Master Mix, is a convenient kit designed for highly efficient cDNA synthesis and highly specific real-time PCR in a single tube. The One-Step RT Enzyme Mix contains a thermostable ExcelRT™ Reverse Transcriptase and a RNAok™ RNase inhibitor. Consequently, One-Step RT Enzyme Mix can reverse transcribe RNA to cDNA at a wide temperature range from 42 to 60°C and active against RNase A, RNase B and RNase C. By containing specialized hot-start Taq DNA polymerase, which greatly reduce primer-dimer formation and can be activated within 2 minutes, the 2X One-Step Master Mix features high specificity and is suitable for fast cycle program.

Introduction
Usages： Determination of coliform and fecal coliform for multiple tube fermentation.
Principle: Tryptone provide carbon and nitrogen sources to meet the needs of bacterial growth; sodium chloride osmotic pressure balance can be maintained; Lactose is a coliform fermentable sugars; potassium dihydrogen phosphate and dipotassium phosphate is a buffer; lauryl sodium can inhibit the growth of non-coliform bacteria.
How to use: 1. Suspend 35.6g of the product, adding 1 L of distilled or deionized water, heated to boiling stirring until completely dissolved, packed in a test tube with a small down tube, 121 ℃ autoclave 15min, leave to cool to room temperature, standby . 2.Sample handling and dilution. 3.Selected three consecutive dilution, each dilution was inoculated three LST broth tubes, each tube was inoculated 1mL. 4. Put the tubes in an incubator 36 ± 1 ℃ cultured for 48 ± 2h. 5. Observe the results. if all LST broth don’t pruduse gas, can be reported as negative for E. coli, if gas production then will have to make further confirmed by experiments.
Quality control: Quality control strains were inoculated and culuture at 36 ± 1 ℃ for 24h ,results are as follows: Bacterial Name Bacterial No. Growth Status Gassing Escherichia coli ATCC25922 good +
Salmonella typhimurium CMCC (B) 50115 good —
Staphylococcus aureus ATCC6538 inhibited —
Storage: Store in a dark, cool and dry place, tighten the cap immediately after use. Storage period of three years.
T4 DNA Ligase is an ATP and Mg2+ dependent dsDNA ligase which catalyses the formation of a phosphodiester bond between 3’-hydroxyl and 5’-phosphate termini in duplex DNA, duplex RNA and some DNA/RNA hybrids. T4 DNA Ligase is active on both blunt-end and cohesive-end substrates. It is also completely inactivated by incubating at 70°C for 10 minutes.
This is a high-quality (commercial grade) version of the T4 DNA Ligase. T4 DNA Ligase is recombinantly produced in E. coli. ArcticZymes’ T4 DNA Ligase is extensively tested for contaminating DNase and RNase activities as well as residual host-cell gDNA.
Key Features
ATP and Mg2+ dependent dsDNA ligase
Easily heat-inactivated at 70°C for 10 minutes
Extensively tested for contaminating DNase and RNase activities as well as residual host-cell gDNA
Applications
Ligation of dsDNA

The BK virus is a member of the polyomavirus family. It has been suggested that this virus may be transmitted through respiratory fluids or urine, since infected individuals periodically excrete virus in the urine. BK viral infections are typically asymptomatic in healthy individuals, however very mild symptoms may appear including mild respiratory infections and fever. Infections with BK virus in immunocompromised or immunosupressed patients are much more severe and may involve renal dysfunction. In fact, in kidney transplant patients the immunosupressive drugs required for the transplant may allow the virus to replicate within the graft, resulting in a disease called BK virus nephropathy (BKVN). The JC virus is a type of human polyomavirus and is very common in the general population, infecting 70 to 90% of humans. Most people acquire JCV in childhood or adolescence. Typically the infection is subclinical and no of consequence in individuals with healthy immune systems. The initial site of infection may be the tonsils or the gastrointestinal tract, and the virus then remains latent in the gastrointestinal tract. JCV can also infect the tubular epithelial cells in the kidneys, where it continues to reproduce, shedding virus particles in the urine. Also, JCV can cross the blood-brain barrier into the central nervous system. JCV is known to cause the usually fatal progressive multifocal leukoencephalopathy (PML) by destroying oligodendrocytes in the brain in immunodeficient or immunosuppressed individuals. The JC and BK viruses are very similar, with their genomes sharing 75% homology. It is however important to differentiate between the viruses due to the differences in pathology and especially the invariably fatal outcome of PML which is only caused by the JC virus.

Storage Conditions and Product Stability All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
